This is a third bottleneck, earlier than the 2 we already knew about.

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.

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.
