Again, this is a minor detail, but anyhow a good argument for the hypothesis of the hereditary defect of the human psyche. It is obvious that stone tool making tells quite directly about a very old, more than 2 million year old genetic defect that became much later the core of all humanity.
The pivotal point in interpreting the early human evolution in my hypothesis is to understand how the stone tool making begun in the first place. For some reason, this question seems to be completely ignored in the studies. Instead, the first question is “who were the first stone tool makers”. This sounds like we wanted to find this “mystery species”. But how a single species can be the explanation for making tools?? Species as such do not explain anything, it means just asking the question in different way. I’m positive new features like making stone tools did not appear to everyone at the same time. This is evidenced by the rather small number of finds; if each and everyone could have made stone tools, there would be many more to be found.
So how did the stone tools come from then?
According to my hypothesis, they came by few individuals who carried a special feature in their psyche. Most likely it was a genetic defect (and could have spread like colour blindness) affecting the behaviour by not allowing one to grow psychically into full adulthood. When these affected growing individuals were deprived of mental adulthood, unlike other members they were unable to adapt to their environment but, instead, wanted to modify it to make their life easier. For this they created stone tools.
In this video there are clearly right and interesting notions, including the fact that tool making changed the physical appearance of the offspring over time. That is very plausible. However, the most important question still remains here unanswered: why did early humans start making tools in the first place?
