As many of you know, I am interested in a wide variety of subjects besides law.
One of those subjects is the development of modern man, Homo sapiens sapiens. According to current thinking, our earliest ancestors emerged in South Africa approximately 200,000 years ago and nearly died out due to severe climate change. A small group managed to survive quite well in a temperate climate living in caves along the coast of South Africa with easy access to the sea to harvest fish and shellfish and just short distances inland to dig up various nutritious roots and gourds. Kind of a Garden of Eden, if you will.
In an article just published in Nature, we find out that by approximately 71,000 years ago, modern man had developed a technology to produce thin sharp stone blades by heating a certain type of rock to a certain temperature and sustaining that temperature for a definite period of time. This process changed the character of the rock so that it could be struck at an angle producing the thin sharp blades that they used to create arrow points and spear points that they could launch long distances accurately with a sling called an atlatl.
Until this recent find, scientists believed the earliest appearance of this technology was approximately 60-65,000 years ago.
Here is a link to the article which contains additional information that I think you will find interesting.
In case you were wondering, the answer is “Yes.” Every human alive today is descended from that small group of early humans.
Therefore, there is no basis and there never was any to believe that one race is superior to another. We are all genetically the same with only minor, mostly cosmetic differences.
The human love affair with psychedelic substances probably was well underway when this discovery was made and who knows — maybe the idea to heat and treat that particular type of rock came to one of our ancestors during a psychedelic experience. Certainly psychedelic experiences with psilocybin mushrooms must have played a role in the human development of cosmology and religion.
Is there a reason why our brains have chemical receptor sites for psychotropic substances?
