@unit5421 Beavers have a more diverse gene pool than humans. Humans almost became extinct about 70,000 years ago due to a massive volcanic eruption. Only about 5,000 people survived it is thought. Then 40,000 years ago only a few thousand migrated out of Africa. 98% of the genetic diversity is in Africa, only 2% in the rest of the world. As people spread out, each group had less diversity than the parent group. By the time you get to the edges of the Eurasian world island, places like Norway, you are a tiny splinter of a splinter of humanity.
