In the ancient times, out in the middle of Russia....there was this 'hybrid' of man called the Denisovans. To be honest, other than one single bone so far.....they haven't really found much to lay out this story.
So from the bone business, they've come to this interesting DNA situation. These were the people who were all built up to be natural autism 'carriers'. Yeah, they were the star-counters, and consumed with passion over anything they thought about.
I saw a podcast this week, and the topic came up over their autism angle.
So you imagine this valley in the heart of Russia....where fifty-odd folks lived 40,000 years ago, and every single one of them are some stone-age 'Sheldon Cooper' type individual. They probably had 15,000 words in their vocabulary in a short amount of time. They probably charted more than 3,000 stars. They probably had more than 1,000 food items to be prepared over a open fire.
Freaks of nature? Well...it just makes you wonder. And what happened to them? That's another thing you have to wonder about.
Footnote: Austism folks are three times more likely to have paranoid schizophrenia. So this tribal unit might not have had a long span of time.
