One more is that some people in the Himalayas (Nepalese, Tibetans, etc.) have some pretty recent adaptations for living at extremely high altitudes where there’s less oxygen. This Wikipedia article has more examples of recent adaptations: https://en.m.wikipedia.org/wiki/Recent_human_evolution
Another interesting factoid is that Africa has more genetic diversity than the rest of the world. So, don’t sleep on the fact that that Homo sapiens spent more time radiating throughout Africa than radiating out of Africa.
I've read that people in Colorado have far more blood carrying capacity from the high altitude. Seems something one can develop.
Super cool, thanks!
