Basically, it warmed up pretty good in the interior of Africa millions of years ago, so our forebears headed “to the beach”—to the ocean shores, swamps, and lakes—where it was more bearable. We foraged for food in the shallow waters and found it beneficial to stand upright, for it allowed us to go into deeper waters and gather more, and for longer periods. Naturally over time bipedalism traits were the ones that won out through natural selection.
But when we became a standing species, it added birth trauma and premature birth to our “species set.” For with this rearrangement of our posture, we created a narrower pelvic opening and our prenates no longer hung loosely below us but pressed down upon the arteries below to create fetal malnutrition. The prematurity of birth was caused by the narrower pelvic opening, as the baby needed to leave the womb earlier than other species in order to make it out. This meant that we would do a great deal of our early life’s learning and development—much more than any other species—outside of the womb and in the context of society, not Nature; this is called secondary altriciality, which is something unique about humans.
With all of these developments — prenatal fetal malnutrition, premature birth, and secondary altriciality—we had greater pain and trauma at the beginning of our lives than any other species. We needed to grow a bigger brain—with an additional brain structure, vastly multiplied neural pathways, and a split brain—to deal with this pain in order to survive. The larger skull added further to birth trauma; it was even more difficult to get through the pelvic opening, and so it required even more prematurity of birth.
All this development outside the womb and increased brain size resulted in language and culture, with all its complexities. Split off from horrible early pains and discomforts, our minds created substitute reflections of our early memories in our cultural products. We created an artificial consciousness construct—an Ego—as an intermediary between the impulses from our insides, emanating from early discomforts, and the stimulus and information coming to us from our current reality.
Its egoic product — that is, what we end up thinking is real — would be the distorted amalgamation of the past — early pain and the learning built on early discomforts — and the present—our present-time situational reality, including the twisted cultural products within and without. So what the Ego came up with would not be true, for its purpose would be to allow us to survive, regardless of bothersome early imprints.
We called the accumulation of cultural product the “advance of man,” and patted ourselves on the back for our Promethean achievements, deeming ourselves superior to Nature. To congratulate ourselves, we needed to ignore all the evidence of savagery on a scale not seen in the rest of our world, which we perpetrated on each other and on the world of Nature.
In all this abominable acting out, we were manifesting aspects of our early pain that we were clueless about, and so created a mirror image of our early experience and its horrific pain and trauma in Reality itself. So it is that, all our early trauma has led us to unthinkingly plod to the edge of oblivion, as we re-create war, fascism, class war, racism and bigotry, environmental pollution, nuclear radiation, loss of ozone layer, threat of nuclear war, and all the rest of the dire threats I’ve been discussing as being act outs of our early prenatal discomforts—crowdedness, deprivation, disgust, and irritation/burning.
So, we stood upright; and now, unless something radical happens, it will lead to the end of life for ourselves and possibly everything else on this planet in short order.
