How did human get to the western hemisphere?
Years passed by and eventually the bridge slowly broke away and decaded. Many of the animals and humans that had crossed the bridge earlier had no means of getting back to the eastern hemisphere and made their homeland on the western hemisphere. Eventually they were forgotten about until they were rediscovered by explorers from the eastern hemisphere who seemed to advance much faster than their brothers on the other side. This lead to the West becoming settled by the East.
