So, like, let me get this straight...

There was a way to walk between the two continents? And the weather was cold enough that ice was walkable between the two countries? Then it was warm enough for people to actually live in those areas? But it was cold enough to walk?

And none of this was caused by SUVs and coal-fired power plants?

During the glacial period the sea levels were much lower, perhaps by some 400 feet. That left a lot more land available for walking.

It was cold, but areas that are now under water were then dry.
