Specifically, this affects the entire human population.
The other 2 bottlenecks were specifically the humans which moved out of Africa - with one being as humans crossed into the Middle East and a second as humans crossed the Bering Strait.
No this is different, actually. The other event is the hypothesized genetic bottleneck triggered by the Toba supervolcano eruption only 74,000 years ago as opposed to 900,000 years ago for this newly proposed event.
I feel like we knew this years ago. Is this another way of confirming it?
This is a third bottleneck, earlier than the 2 we already knew about.

This third one was earlier, and covers all humans, even the ones which never left Africa. These are separate from the more localized “founder events” that we see all over the world.
Ooh thanks, I did not know this!

Fascinating!
