After 300k years ago people are called anatomically modern humans, not “final copy” humans. Evolution never stopped. And even if evolution did stop, consider that developing primitive technology, language, and culture (eg wearing of clothes, a notion of “fairness” or “justice” so conflicts can be resolved without killing people) into something that’d allow humans to be as environmentally adaptable as they are today could itself take a long time. Humans didn’t “stay in Africa” and early Homo sapiens certainly didn’t wait until 10k years ago to spread across the planet. Going off memory here but pretty sure the current theory is early Homo sapiens started to spread out of Africa about ~70-60k years ago. 10k years ago is around when agriculture and “civilization” began. Also other hominids, arguably a kind of human, like Neanderthals and homo erectus had left Africa well before 100k years ago - considering they were probably more adapted to their environment in many cases it’s not that far fetched to think their presence generally made it harder for early Homo sapiens to displace them or coexist with them, given they’d occupy similar ecological niches.
