I’ve never understood that number. I’ve read that modern humans have been around for 200k years, but I’m supposed to believe that for 3/4 of that time they stayed in Africa? BS. Maybe proof hasn’t been found, yet. But we know from our own experience that modern humans love to explore. I don’t believe that love of travel and adventure and exploration is cultural. Our modern ancestors would’ve been exploring out of Africa long before 50kya.
