What all mammalian animals have in common is that they share the workings of a spinal column topped by a brainstem. Fundamentally, these are essentially the same in all of us animals. The brainstem contains the pathways to where all brain activity passes through to the rest of the body and is structurally connected to and a continuation of the spinal column.
Humans have the largest brain in the animal world compared to body size. In any animal that has the remarkable features of having a large brain that works in tandem with an equally remarkable anatomical tool such as the human hands you will likely see extraordinary strides in their evolution. When this brain and its hands are components of a bipedal, upright creature, it suggests that freeing the hands and arms from the job of forelimbs added to the evolutionary development of hominids that is unmatched on this planet.
We tend to describe early humans as hunter-gatherers but in fact, all animals are hunter-gatherers of sorts. It was the progressively efficient hunting skills of humans, however, that enabled them to enjoy a regular diet of meat and fish. As the human brain grew larger so did humans acquire more meat in their diet which led to increasing brain size.
Hunting led to the development of tool-making, which in turn led to cooperative teamwork, the teamwork led to the necessity of communication, the communication led to the need for verbal skills, all of which contributed to communal forethought and planning. While the brain was evolving, the natural selection of both our hands and feet occurred along similar lines that contributed to our increasing manual dexterity and foot balance for walking and running.
Unfortunately, it’s when we turned the development of the hunting tools of our hands, cleverness and communicative skills into weapons that the human species began to cannibalize itself on a large scale.
The primitive evolution of our consciousness was and is trapped inside of a body too advanced for its own good.
Even today, fear, ignorance and superstition dominate the mental evolution of Mother Nature’s quintessential fighting machine. We live in a death culture where our magnificent tools of precision and beauty are conjoined with a never-ending nightmare of self-inflicted predator and prey.
We are, indeed, our worst enemy.
Therein lays the paradox of human evolution.
