A Study Says You Owe Your Existence to Just 1,280 Humans Who Almost Went Extinct

A Study Says You Owe Your Existence to Just 1,280 Humans Who Almost Went Extinct


Well, if you ever wanted to go back in time to fix something.

" ...were down to about 1,280 breeding individuals 930,000 years ago."

A small population to be sure. But still big enough to produce a viable gene pool.
 
Neanderthals didn't emerge until 400,000 years ago.

The bottleneck is 117,000 years long.

A million years ago is the end of the second golden age, could 1,280 have survived it? Or is this realm protected from all that development? I've seen rock walls from the era, the regolith doesn't look recent.
 
The coming bottleneck is going to be 1,280 rich guys.

But if the study's conclusions are valid, then it would seem that we were very nearly on the losing end of the gene wars. Surviving with such a low population at a time when we were just as likely to be a hyena's or lion's next meal took some adaptivity, and probably some luck as well.

There was another, much more recent, genetic bottleneck about 74,000 years ago. Mount Toba, a supervolcano in Indonesia, erupted and is believed to have killed all but 3,000-10,000 humans alive at the time. It would have caused a volcanic winter lasting several years, and global cooling lasting nearly a thousand years. This is the closest that modern Homo Sapiens ever came to extinction.

But if you fix it, how does the time machine ever get built?

It got built in the other continuum.

After you fixed the problem, the continuums merged and no-more need.

And it finally did in those little Australopithicus bastards.
