Where did you get those "1,000 human alive"?

What I read on that page is:

According to the genetic bottleneck theory, between 50,000 and 100,000 years ago, human populations sharply decreased to 3,000–10,000 surviving individuals. It is supported by some genetic evidence suggesting that today's humans are descended from a very small population of between 1,000 and 10,000 breeding pairs that existed about 70,000 years ago.

I was wondering that myself

This event is always good to point out when people discuss anything about race. Humans have very little genetic diversity. Height and color features are nothing, we're basically all the same around the world

But 2/3 of the genetic diversity we have is in Africa

Yes but the point is even that so called diversity is nothing, it's fractions of a percent, mainly certain disease resistances/weaknesses like malaria and genetic disorders IIRC. In the overall human genome the differences are extremely small.

Separating humans by race is ridiculous the more you dive into genetics

Imagine alien species that didn't have this bottleneck. It might just be warfare along racial lines all of the time.

Truly the stars had to align for us to exist like this, I think.

If it wasn't for the Toba eruption, there would be vastly more genetic diversity among the human population and we might have evolved X-Men by now.

X-Men: Emo fictional characters driven by the need for episodic sales with scientifically impossible abilities. Sure!

Sorry. Traumatized by my childhood best friend’s Marvel obsession.
