The Age of Myth – Chapter Three

In review, since discussing the development of language, speech and social progress waylaid the timeline of the evolution of humans somewhat, hundreds of thousands of years before such things as Homo sapiens, Homo erectus had gradually made their way up the Great Rift Valley and out of Africa. Around 400,000 years ago they would be joined by another group of humanoids slowly making their way out of Africa, Homo neanderthalensis, who instead of spreading out through the Middle East and Southeast Asia as Erectus had done, the Neanderthal would make their way their more northwards, in the direction of North Africa, Europe and central Asia.

The Neanderthal’s adaptations were a low brow skull, which was much larger than Homo erectus, and were slightly taller, shorter limbed, barrel-chested, strong, thick bodied and possessing incredible endurance. The reasons for such adaptations were because the Neanderthal became a cold-adapted people, surviving, often times, in a harsh and brutal environment upon an extremely cold landscape.

With no material comforts to speak of, they travelled in small bands of perhaps a dozen in number and were scavengers, hunters and gatherers. And though early humanoids are deemed by our present society as dim-witted cavemen, the realities of a hunter-gatherer lifestyle is the punishment for stupidity was more often than not death.

With the land used jointly with other bands, they never really had any permanent place of residence and would move about seasonally. There was no economic specialization except by age and sex for everyone had to help out and forage for food. They survived with no laws, police or treaties to resolve conflict, were egalitarian, with no formalized or hereditary leadership and no distinction of a lower or upper class. Leadership was informal, based on character, personality, strength, intelligence and hunting skills. Indeed they fought, but there was no such thing as war. If fighting ever did break out, very rarely did anyone die. It was all about showing threat signals like posturing, yelling, and basically creating a scene, much like most all other animals, and as soon as the enemy has been subdued or has walked away it ceases to be a threat.

Considering the dangerous world in which early species of humans lived in, their social world existed entirely on the relationships within their family, indeed most all small bands of early humans would only encounter perhaps a couple dozen or less fellow humans over their entire lifetimes, with each band living in solitude for sometimes hundreds of generations. And though they had no slavery, luxury goods, architecture, nor real language, they were highly resourceful, organized, social and intelligent humans. For indeed what has truly driven human, and primate, brain evolution more than other norms is the complexity of our social world. It still does, though today at a much quicker pace than the normal rate of evolution of our social worlds, which was tens of thousands of years.

Tens of thousands of years, time which is hard to fathom and incomprehensible in its vastness. Especially to us today when we think we have advanced, and evolved, so incredibly much in the past 100 years. There are many I’m sure who believe they and their world around them have advanced and evolved in leaps and bounds just in their own generation, on many levels perhaps. But then there are also many humans today still living in hunger and a dirt shack or cave, if they are lucky. It is hard to get perspective when talking about eons of years, especially when a human generation, the average period between the birth of parents and the birth of their offspring, is about 35 years. So to further confuse, ten thousand years represents over 285 generations.

Though having no formal speech yet, the Neanderthal communicated using eye contact, body language, tone and other forms of non verbal communication, and most specifically and important to their survival, by being intuitive and acting by instinct. They might have been able to sense the energy levels of all living things for all we know. Perhaps squat in the forest or upon the tundra and sense things on the wind, listening for a distant sound, smelling the air, the feel of the ground, looking up and studying the sky, clouds, and the position of the sun and moon, noting the behaviour of their fellow humans and the animals around them, sensing the differences and changes in the earth’s energy levels and of each other. Which we can still do today, but such senses are now controlled by others, numbed and dumbed down, or taught to be ignored and not trusted.

But even with such senses, life was still very brutal. Most all Neanderthals never made it past thirty years of age. They hunted large, dangerous animals so they had to work as a group and have a plan, especially since this was before the bow and arrow, and since they had not yet grasped the concept of projectiles, thrusting was the norm, not throwing. Their injuries seem to point this out, with most being to their arms, torso and head, because they had to get up real close to their prey en mass and start stabbing. Four out of every six Neanderthal skeletons found show many of the bones deformed by disease and injury, and perhaps exhibiting that the Neanderthal possessed empathy, many of the skeletons found had injuries that showed signs of healing, which means the lame and crippled would have had to have been taken care of, fed, protected and helped to move by others. They also gave special treatment to their dead in their burial, with the earliest known burial sites dating back 100,000 years.

About 170,000 years ago, anatomically modern humans, Homo sapiens sapiens would begin to drift out of Ethiopia. With a straighter forehead and smaller brow ridges than Neanderthal, they were equally robust, strong, solid and slightly taller, with the oldest fossils of anatomically modern humans found in Ethiopia and dated from 196,000 years ago. Homo sapiens would slowly spread out and as they migrated out of Africa, like all the others before them they would encounter previous human species and rather than destroying them into extinction, most times they were simply assimilated into the newer species.

The warmest time before the last ice age was 125,000 years ago and is known as the Marine Isotope Stage 6.  The planet was covered with coniferous, temperate, deciduous, and rain forests, but also, especially in Africa, much larger deserts. The sea levels were 6-9 m (20-30 ft) higher than modern times while the world’s conditions had begun to deteriorate. Much the land became uninhabitable, forcing the humanoid species still in Africa to migrate. The Neanderthal would settle in Central Asia and Europe, the Archaic Homo sapiens and remaining Homo erectus in Asia, around 90,000 years ago, and after taking over 35,000 years to accomplish it, Homo sapiens sapiens would also finally make their way out of Africa. They would move into the Nile valley, Sinai and the Middle East, with Homo sapiens fossils found in the Middle East and dated from 92,000 years ago.

Ninety thousand years ago the planet began to cool and over the next thousands of years, with the temperature continually dropping and the environment changing, the evolvement of humans continued its snail’s pace advancement. As with social progress, most evolutionary advancements took tens, and in many cases hundreds of thousands of years. The planet Earth also continued to evolve and change, though it had not a care in the world for social progress, the life forms living on its surface or their feelings. And as it often happens, nature makes itself known in not as so subtle means but with changes that are more dramatic, instant, and many times, having a much more profound effect on all things on its surface than anything we humans could ever come up with, though today that could be debated.

According to a theory proposed in 1998 by Stanley H. Ambrose of the University of Illinois, and which today is a much respected explanation for many of the paradoxes of the evolvement of all living things, the super-volcanic eruption 71,000 years ago of Mount Toba, in present day Sumatra, Indonesia, would alter the dynamics of human evolution drastically.

Mount Toba is accepted today as being the earth’s largest volcanic eruption. For context, when Krakatoa, also in Indonesia, erupted in 1883, 11,000-12,000 people were killed instantly; eventually an estimated 36,417 people would also die. With an ash cloud covering about 200 cubic kilometres, the explosion immediately destroyed over two-thirds of Krakatoa Island, sent out an enormous tsunami, and caused the worst global famine of the 19th century.

Sixty-eight years earlier in 1815, and also in the Indonesian archipelago, Mount Tambora exploded with four times the energy of the eruption of Krakatoa. Its explosion could be heard over 2600 km (1600 miles) away. If it had erupted in Vancouver, British Columbia it would have been heard in Mexico. Killing 71,000 people, Tambora is the deadliest volcano to date. A ring of smoke and ash 600 km (370 miles) outwards from the mountain’s summit cloaked the land in total darkness for over two days. The pyroclastic flows travelled 20 km (12 mi). The eruption column reached the stratosphere. Thick ash fell for a couple of weeks while the finer ash stayed in the atmosphere from a few months up to a few years. Before the explosion, Mount Tambora was approximately 4,300 m (14,100 ft) high, after the explosion it was only 2,851 m (9,354 ft) high. Tambora is the largest observed eruption in recorded history.

About 70,000 years before Tambora, Mount Toba erupted, instantly hurling up a sulphuric ash cloud which covered at least 800 cubic kilometres (500 cubic miles). It spread northwest across India blanketing some places by as much as 6m (18ft) deep, and because its location was only two degrees north of the equator; it would have made the dispersion more global. For an eruption’s plume to reach the stratosphere and blanket the entire world with its ash, it would have to be at least 10 km (6 mi) to 50 km (30 mi) high. Mount Toba’s plume reached twice this height. A highly reflective sulphuric acid haze enveloped the earth for six years and a volcanic winter descended over the earth. Sea temperatures cooled, with the global temperature dropping by at least 6C (9F) in the first few years. This cooling period lasted for perhaps a thousand years, with the temperatures colder than even at the peak of the next ice age that was to follow. It likely caused the complete deforestation of SE Asia. How much of Mount Toba disappeared in the explosion? Mount Toba is now called Lake Toba, 100 km (62 mi) long and 30 km (18 mi) wide, 505 m (1666 ft) deep at its deepest and at a surface elevation of 900 m (2953 ft), it is the largest volcanic lake in the world.

The populations of Europe and Northern China were nearly completely eliminated. It is estimated that the planet lost 60-75% of its populations, with the extinction of all human species except for Neanderthal and Homo sapiens. Survivors found relatively safe havens in isolated pockets, mostly in tropical, equatorial Africa and Northern Europe. The human species, as well as many other species of animals, were decimated. Supported theory and genetic evidence suggests that only perhaps 10,000 adult humans survived, maybe less; this is an estimate of ancestors, not of total human population. Isolated human populations that eventually died out without descendants may have also existed in numbers but cannot be estimated by geneticists. Wherever on the planet early humans and other animals lived dictated if they would perish or survive, and rather quickly humanity was thrown into a population bottleneck, which is perhaps the reason people look so different today. A population bottleneck is when a large population is broken up into smaller groups, and causes a “founder effect”, where small, new populations begin to appear and through genetic drift, inbreeding, and local adaptations produces rapid changes to that group’s gene pool, creating similarities only amongst that particular group, with low genetic variation. This is followed by an eventual rapid population increase, innovation, progress and migration. Genetic evidence suggests that all humans alive today, despite apparent variety, are descended from these small populations that survived the eruption of Mount Toba, estimated to be anywhere from 1,000 to 10,000 breeding pairs of humans.

As genetic studies have proven, all humans today are descendants of a woman in SE Africa, called Mitochondrial Eve, around 140,000 years ago; mitochondrial DNA is inherited only from one’s mother, with Y-chromosomal Adam, (from one’s father), added to the gene pool about 60,000 years ago. This can be seen in the native population of North America, in that of all the thousands of humans that had migrated there more than 15,000 years ago, only 72 descendants’ lineage has moved on into modern times.

As with all biological bottlenecks, the remaining, separated and isolated group’s development would bring about significant changes which enhanced human fitness, the ability to survive and reproduce. The survivors of Mount Toba’s eruption, once the climate and other factors permitted, began to fan out from Africa and elsewhere. Travelling in small groups they became ever more isolated from one another and would evolve separately. Some would cross the Red Sea, which was not much of a sea at the time, into the near-East, and from there moving along the exposed areas of the continental shelves. With an ice age underway glaciers had formed, crushing the forests and all that lay before them as they slowly crept along. While both, the temperature and the sea levels continued to drop. Obstacles such as the Mediterranean Sea and the English Channel would be easier to cross because they were valleys, with perhaps a river running through them and scattered lakes strewn about the valley floor, same for the Black Sea.

By 65,000 years ago the glaciers had covered about 17 million square miles, with the polar ice caps expanding over the globe, covering much of present day Europe, Britain, Canada, and parts of Asia, including the Himalayas. By 60,000 years ago bands of humans had made their way along the shorelines of Arabia, India and South-East Asia and by 40,000 years ago, some of them had made their way to Australia, others into North-East Asia and China. With Australia and New Guinea always having been isolated by water, even during an ice age, evidence suggests early Australoids were the first to develop some form of boat building.

By the time before or after peak glaciations of the last ice age, 18,000 years ago, other groups had finally made their way into the American continents, and as the ice melted would become separated from the main race and develop in geographical isolation as well, becoming American Indians. These groups of people would eventually spread southward to South America reaching the last place on the planet to be colonized by humans, Cape Horn, around 8,000 years ago.

When the first explorers reached this most southerly point of South America and the islands of Isla Grande de Tierra del Fuego, which is separated from the continent by the Strait of Magellan, they were shocked to find that there were four separate peoples that inhabited these islands and that each group looked different from one another and that they spoke two different languages. It is still a mystery how these original peoples had got there, and from where.

Besides the original Negroid race of human species, the people that had made their way to the north would become the Caucasoid and the ones who ventured into Asia would become the Mongoloid. By 45,000 years ago these three races could be defined as the main races of humans and would attain nearly complete specialization in their respective environments. The early inhabitants of Australia had developed from an earlier, less developed race in isolation from this specialization of the main races and became the Australoids. Thus, from human variation through physical adaptation to their climatic conditions, the races of mankind would form.

In the northern regions, with less and weaker sunlight, humans would eventually become more pale, though the actual process would take about 20,000 years. Our biological body takes vitamin D from the sun’s energy to aid in the proper growth of bones. Living in the northern latitudes where there is less sunshine the skin has to lighten to let more sunshine through. Just like people in equatorial latitudes who get sunshine nearly all the time and whose bodies, needing protection from UV rays, secrete melanin, the body’s natural sun screen, and which we all have, into the skin to darken it. The differences between the races are very much “skin deep”, with the most recent adaptations to our species occurring about 20,000 years ago, and include the parts of us that interact with the world around us; skin colour, immune system, and metabolic changes due to the digestion of unique foods, amongst each race. And because we are one species, originally evolving in Africa, this ensured that racial and ethnic groups were and are biologically equivalent, no matter where they ended up on the planet.

Human genetics prove that any racial superiority is a myth, because intelligence is not a single trait; it’s a huge entourage of abilities. Each race has an ancestral environment that favoured a different set of talents, with each race best adapted to their unique environment. We are all fundamentally different, thank god, and regardless of where one is born, each and all individuals are deserving of the same rights and opportunities. Every one of us brings different strengths and talents to the table, and this is why the most democratic, invigorating, and creative places on the planet are multi-racial cultures.

Some 40,000 years ago, a more complex human culture had spread and sustained itself in Africa, then Europe and Western Asia, and by 30,000 years ago social change had reached south east Asia and Australia. It was the dawn of consciousness, with modern human behaviour slowly emerging, in different regions at different times. Besides changes in human behaviour within a more complex culture, one of the more significant things to alter human history also emerged about 40,000 years ago; now having a larger size brain, the human mind, along with its ego, began to unfold itself.

According to Austrian neurologist, Sigmund Freud (1856-1939), there are two functions of our brain that make up our unconscious mind, the Id and the super-ego, and along with the ego, which is our consciousness, are the three divisions of the mind. Though some of Freud’s psychoanalytic theories have largely been marginalized today, mostly because most of his subjects were rich, middle-aged, aristocratic, pent up women, his concepts of libido, drives, the unconscious, and his ideas that we repress or bottle up our feelings, and that our family relationships when we are children determine our adult relationships, have made important contributions to neuroscience. Though the actual benefits of intensive psycho-therapy have been controversial in the past; seeking clues into the unconscious roots of disorders today experts report that such therapy can be effective against chronic mental problems such as anxiety and depression.

Freud believed the Id is the uncoordinated, instinctual structure of our ego and includes selfishness and the need for instant self gratification. It is unconscious and represents the mind of a newborn. It consists of our basic drives, such as food, water, and basic impulses. It is where our libido, the instinctive drive to create comes from. It is amoral, egocentric and ruled by the pleasure-pain principle. It does not have a sense of time, is completely illogical and infantile in its development.

The super-ego is also mostly unconscious and is the organized part of our personalities. It contains our individual ideals, spiritual goals and our conscience. It always strives to act in socially appropriate behaviour. It is what controls our sense of right and wrong and guilt, and allows us to fit into our society in socially acceptable ways. Through symbolic internalization of the father figure, male or female, and cultural regulations, it becomes a part of our personality and conditions us to conform to society’s expectations. The super-ego maintains our sense of morality and prohibits us from cultural taboos.

The super-ego and the ego are the products of the state of helplessness of childhood; for we are born ego-less and have no distinct being, apart from the world around ourselves. This lasts until we are about five years old. At which time our ego and libido begin to develop. What Freud would call the Oedipus complex, the unconsciousness, repressed feelings and ideas we have that are centered around the desire to please the parent of the opposite sex and ignore the parent of the same sex is either, rapidly repressed or not, by how powerful the Oedipus complex was. From about five years onward, by the influence of authority, religious teaching, schooling, and reading, as well as how deeply the repression of the Oedipus complex is, the stricter the super-ego will be over the ego, in the form of having a conscience or an unconscious sense of guilt.

The ego acts according to the reality principle. Its task is to find a balance between primitive drives and reality. Because the Id’s drives are usually unrealistic, instant and short-term, and most times filled with grief, the ego seeks to please these drives of the Id in realistic ways that will benefit long term instead. The ego separates what is real and organizes our thoughts and tries to make sense of them. It also tries to make sense of the world around us and is modified by influence of the external world, reason and common sense. The ego will become defensive if the Id’s behaviour conflicts with reality, society’s morals, norms and taboos, or other individuals who believe in these rules of a culture and expectations.

Many of our problems today are because everything is moving too fast. Where once changes in our social worlds would take thousands of years, generations or decades, today there is simply no time to reflect and ponder. As to our minds, our self-gratification via consumer culture is travelling at an ever quickening pace which is not a problem for the Id. It can easily keep for it does not understand time, while the super-ego is being ignored and left behind in the dust, with the ego simply along for the ride.

After 40,000 years the ego has decided today to be more loyal to the Id than the super-ego, which makes it dysfunctional. Thus, here lies our current state of affairs. The norm has become instant self-gratification of all our desires. We are completely defined by our culture, while early humankind’s culture was the family and there was no time other than the present. Early humans might not have had much of a personality, but they were living in the moment, emotionally, like a child in many ways with nearly no ego to speak of. But as time marched on and became civilized, the ego began to gloss over the fine details of reality to minimize conflicts with the Id, while only pretending to have any regard for reality. Because the super-ego is always watching the ego, it has been punishing it with feelings of guilt, anxiety, and inferiority. To overcome the beating it is taking the ego fights back using denial and displacement; transferring the focus of an emotion to something else, intellectualisation; where reason is used to block out any emotional stress or conflict, regression, fantasy, control, or dissociation; splitting off from main body of consciousness, and in some cases; hysteria, suppression and substitution.

The main two functions of our brain, the duality of the id and the super-ego and their interactions, could have been the basis for religion being invented a few thousand years ago. The sum total of all the sacred scriptures, of all the organized religions combined, is basically about two gods, good versus evil, though in reality and hidden behind some bushes, they are really talking about the two sides of who we are, our nature and the mechanics of the mind; the representations of the human soul.

Within most organized religions there are usually two gods, one being a benevolent, pure in thought, righteous, just, honest, who possesses grace and is humane, kind, and compassionate, promises hope and an afterlife, and is capable of establishing a new heaven and earth. This god is usually all-knowing, an infinite spirit, without limitations, eternal yet everywhere and all-powerful, in other words, a human of good character.

The flip side is of a malevolent god, who is filled with intense, often vicious ill-will, spite and hatred and is selfish, highly jealous and immoral, who grows proud, and desires to be God, who has a flawed ambition, is greedy, egotistical, self-satisfying, who is known as a tempter, accuser, murderer, liar, and a enemy and who is related to inhabitants of bottomless pits, dragons, destruction, ruin, fire, violence, racism and hell; basically a hindrance on society, and an asshole.

Both of these gods are not dwelling in a heaven or in an underworld, or standing towering over us, they are not supernatural beings to be feared and to worship, they are actually residing within each one of us and are the functions of our minds. Earlier humans inherently knew the authority to create and destroy, to either reject or punish, to demonstrate both ecstasy and terror, love, and hate was theirs alone, and understood the responsibility of it and how one’s actions affected others in their group. Organized religions would take this authority and responsibility away from humanity and would become the authority itself, to dictate its own perceived morality and beliefs.

What has changed the most since organized religions took power over us, within the formation of civilizations, is in our personal and collective unconsciousness. Our collective unconscious is the deepest level of who we are and is the accumulation of inherited experiences, while our personal unconscious is the reservoir of material that was once conscious but has been forgotten or suppressed over the millennium, meaning we now live almost totally embedded within our mentally constructed realities, our minds filled with continuous streams of thought and fantasy. It is interesting that of the world’s religions and their concern over our hearts and minds, Eastern religions such as Buddhism, Taoism, Hinduism, Sufism and Zen, all place much importance on getting past such mental behaviours of the ego and its refusal to live in the present moment and instead try to understand the truths behind them through meditation and reflection, while Western religions and cultures believe that a state of continual mental distraction is just the natural order of things. But before we get too carried away yet once again, we must return to the discernability of 40,000 years ago, and the birth of modern man.

The Age of Myth – Chapter Two

The Great Rift Valley of Africa runs 5,600km (3,500miles), from the Red Sea and Ethiopia in the north, south to Lake Victoria where it splits off, and from Uganda continues south as far down as present day Mozambique. The Great Rift is where two plates of the earth’s crust are separating and is also where our human ancestry seems to have begun.

The earliest traces of man have been found in the valleys of Lake Turkana in Kenya and the Olduvai Gorge in Tanzania, between Mount Kilimanjaro and the Serengeti Plain. The Olduvai Gorge itself is a 30-mile long gash in Tanzania’s Serengeti Plain. The area is considered the primary host of all other cultures. Why this is so will be explained as we go.

Evidence of the earliest Humanoids has been found and dated from 4 to 1.6 million years ago in Tanzania, 700,000 years ago in Java, and 420,000 years ago in China. From sites found in the Olduvai Gorge in Africa and elsewhere, these early peoples favoured lakeside camps, rock overhangs and caves for protection from predators and the weather. Their camps were most always near water availability, like rivers and lakes, and close to herds of game and vegetable foods. They would stay in each camp for a few days or weeks before moving on to better land. Many of these sites also contain bones of smaller animals, species less powerful than these early humanoids.

Hunting seems to have been more running down and grappling their quarry to the ground, with scavenging the more important means of getting food, with their weapons most often being made out of wood. These early humanoids were opportunistic hunters, picking over carcasses from predator kills and gathering wild vegetables. At the time, the larger animals were kept at a distance and avoided, for they were not afraid of man yet, indeed to many of the larger predators, early man was inconsequential and often the prey.

These early humans were bipedal, had an upright posture, a high vertical forehead and rounded skull, were about 1.5m tall, and became the species, Homo erectus. For when earlier species had first moved out of the trees and the forests and onto the grasslands they had begun to walk upright, to see over the grass. By about two million years ago, Homo erectus had spread out over Africa, Asia and Europe, with their descendants thought to be the first humans to use fire.

From watching fellow creatures they would eventually develop memory and foresight, and by mimicking the behaviour of the other living things around them they would assimilate such things as trapping; from the spider, basketry; from birds, burrowing from rabbits, dam building from the beaver and the art of poisons from snakes. These early peoples did not think themselves as being different from the rest of the animal world. With no language, they grunted and squawked like everyone else. From copying the other creature’s diets, mostly fruits and vegetables, to watching how they would get their food and how they would store it, they became very adept at exploring their surroundings and keeping a memory of which plants, insects and small animals one could eat and which ones were to be avoided. Their reality was a world of animal, vegetable and human spirits interacting with each other. They could not tell the difference between material and immaterial, imaginary or real, animate or inanimate. With no idea of self, there was little difference of skills, and having no idea about the concept of surplus there wasn’t much difference in status distinction between each other. The sensations that bombarded them daily needed an immediate response, so life was lived very much in the moment with not much thought about past or future. One’s life was determined by one’s actions to what was happening at that moment, at that time.

Because of their intimate connection with the earth, they expressed great care for its well being, for they believed that they were simply one part of the earth’s body and did not distinguish themselves from everything less in nature, thus they did not possess the sense of self, only the concept of their groups survival. Their culture consisted of a father, mother, siblings and extended family members, perhaps a dozen individuals, whose only concern was each day’s survival as a group.

Everything in nature represented a spirit or demon, depending on whether looked at as friend or foe, with animals and trees considered human but simply in another form. And because they did not see themselves as finite mortal beings they did not believe that people died, but rather they went to sleep and their spirit entered a netherworld and/or parallel existence. As to birth they also had no idea, they did not make the connection that sex had anything to do with the birth of a child, instead believing a spirit would enter a female’s body and then be brought forth, with a baby thought of as being half spirit and half human, who remained in contact with the world it came from until which time it grew up and then, sometimes over years, would have to pass through various rites of passage to become a part of the community. Because having too many babies would prove to be a hindrance to the tribe’s survival of having to be always on the move, a woman could only carry one child at a time and until that child could keep up on its own to have another was no doubt forbidden. Biology took care of this issue; women would breast feed their child for two full years, thus enabling suckling to be the contraceptive technique that it is, by repressing the menstrual cycle. The average reproductive cycle of most of the women, over an average life span of about thirty years, was perhaps 10-15 children, though of course we do not know an actual fertility rate.

The evolution of all species is all about natural selection, with many similarities in all living things. For example, creatures known as vertebrates – having a backbone – all share the five digits, skeletal structure of a hand. This appears not only in humans but also in apes, raccoons, cats, bats, porpoise, whales, lizards, turtles and a plethora of other creatures. Dolphins are able, as we are, to call each other by name. At the same time it is curious why many male mammals, including humans, have nipples. All animals share the same basic bodily functions and feelings, such as pleasure, pain, breathing, eating, drinking, defecating, sleeping, the drives to find a mate and procreate, birth, and death. For humans especially, history has followed different courses for different peoples because of different environments, not because of any biological differences between the peoples themselves.

The fact of the matter is, all humans have the same facial grammar; everyone smiles the same, frown the same, uses the eyes to convey cognition or flirtatiousness the same. A laugh is a laugh, anywhere on the planet and when one is angry, everyone knows they are. Don’t you find that human beings are very good looking people when they smile, and so disgustingly ugly when angry? But it’s much more than that, for instance, when people smile, the mouth doesn’t convey the whole truth. A true smile appears in the eyes and it’s no wonder the majority of a human’s muscles are in our faces, which seems to prove how important expression is in inter-personal communication. Then there is the tilt of the head, arch of the eyebrow or where the eyes are looking when communicating that further convey what one is thinking and trying to say or feel. Without eye contact we never truly know what someone is saying because we are not getting the whole story. The eyes are truly the windows into our soul. Even people that don’t understand what each other are saying can look at each other and communicate more than words could possibly describe. In Donald E. Brown’s excellent “Human Universals” he finds that there are about 400 specific behaviours that are invariant among all humans, with the facial expressions of basic emotions truly universal, and shared by many other animals besides humans, whether it is anger, happiness, sadness, disgust, fear, surprise or contempt.

About 150,000 years ago the evolutionary pace quickened when our skull and its contents evolved to the point where we became able to plan more for specific projects or definite purposes. At about the same time the development of speech and a symbolic system of language began, which allowed future cultures a much quicker way to share ideas that enabled them to cope with their environment. As language became more complex it allowed the ability to remember, transmit, and exchange information much more quickly and it allowed for such knowledge to be passed on through the ages, where myths through oral traditions would form, though it would not be until 50,000 years ago that language and culture would really begin to change who we were and who we would become.

Language would eventually give us the ability to create worlds of memories and life histories, and unfortunately, it would make us self-conscious. Before language we could only live in the moment and react to the shifting patterns of our environment, but language brought us the awareness of oneself, in terms of what others expect; humans who sense they are being evaluated and perhaps sensing a negative attitude towards themselves become self-conscious. While being conscious is being aware of oneself and subjectively experiencing each moment and having memory control; where we can think of something and then replay it in our head to examine what we had just thought. Yet we cannot both, think of something and also be self-consciously aware of what we are thinking. Conscious experiences also include inner feelings and thoughts as well as being aware of self and others. Other animals are simply conscious and not self-conscious at all. Yes they are highly intelligent and very aware of the world around them, but they do not look inward and observe the process of consciousness at work. They are not self aware, nor have imaginations, independent will or a conscience, because they are programmed by instinct, genetics and/or training.

There are many views on the origin of language. While it is true that all animals communicate in some way, human language would eventually become associated with the human way of using symbols and speech, while human nature is thinking, feeling and acting, which all humans have in common. Some views state that language is an extension of speech, which all humans have within themselves, with reason the most primary characteristic of human nature. Some believe language developed first, before reason, perhaps explaining many of the negative aspects of human communication. Others believe language and reason co-evolved. While still others believe that reason was developed out of the need for more complex communication, when more sophisticated social structures came about by the gains made by language and/or reason. It is surmised that more sophisticated human behaviour and basic speech both appeared about 164,000 years ago in southeast Africa, beginning with grunts and clicks, with language then evolving at a pace with cultural growth.

Speech evolved from non-verbal mood vocalization signals such as a cry of pain, a scream or a laugh. Other nonverbal forms include the expression of silence, hugging, touching and looking into someone’s eyes. Non-verbal communication is all about tone. While the tone of one’s voice is how the earliest humans signalled one another, speech brought cooperative exchange of information and allowed early humans to refer to objects in their environment. Non-verbal vocalization signals are still very important to us in being able to communicate; in fact they are everything, no matter what the media technology toys of our age tells us. When we cry out in pain, anyone listening can usually tell how severe it is; though with speech we now also add a few choice words along with the cry of pain, adding expression to the experience. Tone of voice is also the reason one can travel to another land and not knowing the language of that part of the world, can still get a reaction and communicate with other animals, even pets, which live there.

The evolution of speech was also connected to the development of the human vocal tract; it’s development allowed a far larger range of sound and the ability to speak more quickly. Our speaking rate has always been connected to the brain, which needs the body to take a breath about every five seconds. The earliest humans that began to speak could say maybe four to five words in five seconds. Today we can get off twenty to thirty-five words in five seconds, in fact a typical human today has a speaking rate of more than two hundred words a minute; three girlfriends chatting could raise this rate exponentially.

Language and speech would alter our brains. In order to operate, the brain needs to understand the inside world of the body and a view of the world outside, to act intelligently and make decisions. Before speech and language the brain relied on the senses. The sense organs would see, feel, hear, and taste to build a consciously experienced picture of the outside world. Sensations such as hunger, pain, and thirst told the brain what it should do to satisfy the demands of the body and because early humans operated on mostly instinct and intuition, the brain allowed rich areas of knowledge to surface in the conscious plane, which early humans would envision, and then do the images that were presented.

Among all animal species we are the only ones who tell stories. Living by the narrative in our communication is important to us because by listening to each other’s stories we are given to needing each other’s companionship and inclined to intimacy, affection, relationships and sociability. Language and speech would indeed change the way we lived and how we were to evolve socially, but at the same time it was when, ever so slowly, we would begin to lose focus on the present moment.

An animal’s mind operates by perception, recognition, simple thought association and environment, and is led by being aware of the moment, much like early humanoids but with language the human mind began operating not only by perception but also with memory, imagination, and more complex habits of thought such as inner-driven attention and self awareness. As humans we are responsible for our own lives, with our behaviour a function of our decisions, not our conditions. The traits of behaviour which sets humans apart from other animals’ starts with self awareness and the ability to think about our thought process, and possessing an imagination, where in our minds we can create other realities. We also have independent will; the ability to act based on our self awareness, and finally we have a conscience, an inner awareness of right or wrong, which we gain from internalizing the moral standards of behaviour of the social group we live in.

Meanwhile, the original groups of perhaps a dozen humans eventually became nomadic bands, basically large family groups of about 25-30 people. Living as hunters, gatherers and foragers, each group would need about 250 square miles (400 sq. km) to support itself. A small band would only have to travel a few miles every couple of weeks, or maybe led by the full moon, move to a new campsite about every four weeks. Most of their travels were just moving back and forth to familiar areas according to the season. In fact for over 95% of our human existence we have lived this way, as foragers and on occasion, hunters. We lived off of what the earth gave us, within daily and annual routines that matched the rhythms of the changing seasons and progressions of each day. Time would be measured only by the sun, the seasons, and the generations.

Most of these early hunters and gatherers diet was made up of nuts, fruits, edible roots, shellfish, insects and eggs, and were dependant on knowing which ones could be eaten and where to find them. To survive they had to depend on their intelligence and knowledge of the land and nature. When available, meat was a welcome addition to their diet whether by spearing big game, snaring small animals, scavenging carcasses left by bigger predators or from fishing. At first they would have had an easy time living off the land; most groups would have been able to gather the food they needed that day in only a few hours.

Beginning with simple wooden clubs, hunting and tool kit technologies would develop further when small game could not sustain the growing populations. These advancements in technologies allowed early humans to go after bigger game. Like the earliest tools, they were still often made from stone, but now would become finer and lighter, with the sharp flakes, broken and chipped from stone, and being used not only for hunting but also for cutting and sawing. As far as hunting, early man found that they could literally walk up to many of the larger animals, for they were not afraid of man. Though during the first million years of our evolvement, early humans were nowhere near being the predator they would one day become. It would take thousands of generations for the larger animals to develop the sense to run or attack when they see or sense a human. As early humans found ever more lethal ways to kill, scavenging was less needed and with the advancement of their tool technologies they were able to start processing the meat and using more of the carcasses such as the skin and bones, to further their advancement along even more and ensure their survival.

Instead of being centred on and preoccupied with oneself and the gratification of one’s own egotistical desires, early humans were more altruistic, where they were unselfishly concerned for and devoted to the welfare of their family. The group needed to be organized and work as a group; even in the pairing up of certain men and women into stable and perhaps loving couples for the better survivability of the child. But then most all animals possess this trait, where the behaviour of an animal, though it might not be exactly to its advantage and perhaps is life-threatening, benefits others of its kind, most often its family. While making up simple tools took a great deal of thought, testing and refinement and was a turning point for human’s evolvement, learning how to get along with our fellow human beings would prove more difficult.

With language and speech, the human ego began to develop and time began to take over our lives. Our thoughts eventually became only concerned with the past and the future. We would begin to rely on our past for our identity and sense of self, while we looked to the future for our fulfilment. This state of consciousness brought forth fear, anxiety, expectation, regret, guilt, and anger into our lives, while our cultures and environments would form whom we have become today, shaped personalities, with our brains filled with a continuous stream of thought. But we should not get too far ahead of ourselves.

Early humans were formed from interaction between only a few people, mostly all family members, the surrounding environment, and their unconscious mind; where the mental phenomena of feelings, perceptions, intuitions, thoughts, habits, and desires, exist. Being an exploratory species by nature, as their populations grew and enough room to forage became intruded upon they would have to move more often, with generation upon generation slowly making their way farther out of Africa.

By about 400,000 years ago, Homo erectus had been joined by another species of humanoid, Homo neanderthalensis and between them had spread throughout Africa, Asia and Europe. Around this time another species would also evolve and enter the mix, Archaic Homo sapiens. Then about 170,000 years ago, anatomically modern humans, Homo sapiens sapiens would arrive on the scene.

First appearing in Ethiopia, these more modern humans slowly replaced all the other populations, while language, speech and more sophisticated human behaviour began to appear, and evolution, brain size and myth would take another slow step forward, though self awareness, lives filled with an almost constant state of mental distraction, and such things as an ego, were still thousands of years away.
