Why did people from Beringia move south when they did?


New member
People are curious and push on to explore what is around them. What's over the next hill or around the bend? Not so long ago we all "knew" that they moved down as soon as they could through the ice free corridor, but today we have reason to believe people were in North and South America long (How long??) before there was an ice free corridor. With the corridor relegated to a much later, secondary conduit, they must have come over water or the ice, or some combination, and we can no longer restrict the first colonizers to a particular time frame: They could have come at almost any time. Regardless of when they actually did come (unless some just kept coming and never stopped in Beringia at all [evidence, anybody]), why didn't they come before then?
Please help.Thanks!
I didn't find the right solution from the Internet.
