Here is my question. How much did continental drift play in the movements of ancient peoples. For example: the new topic is populating the Americas, was it 20000 years ago or was it 140000 years ago. Did the continents get closer to each other or farther apart. Did this effect Sea travel. Were ancient man able to travel these distances because the continents were closer together at a certain time. What was the distance between "OlD" world and the"New world" at the younger dryes period, or slightly before. And could have the cosmic event changed that an any way, speeding process up, slowing process down.
