Anatomically correct humans are designed to run an average 50+ miles a day over a short (2-4 weeks) period and jog an average of at least 20+ miles a day over an extended (near permanent) period. Based on Darwin, bipedal (4 million years ago) ape-like humans wouldn't have evolved into long distance running/jogging machines unless such long distance running was long established as an essential to their survival. Do the math. An entire tribe of humans is quite capable of jogging from Africa to China or vice-versa in a single season with 4 million seasons to beat the path. There was never any reason for humans to come out of any particular place. Their kin were already all over the planet before Oppenheimer's Eve was born
All Oppenheimer is doing is tracing one family line over 160,000 years. Ghengis Kahn is well on the way to accomplishing that same task in a fraction of the time.
"Anatomically correct humans are designed to run an average 50+ miles a day over a short (2-4 weeks) period and jog an average of at least 20+ miles a day over an extended (near permanent) period." Humans have the best endurance of any land mammal. If a human can track and keep an animal on the move, the animal will drop dead of exhaustion before the human does.
Bushmen in Africa (still) shoot an animal with a poison dart and track it for days before the animal dies.
