It Is Now Below The Sea
It goes without saying that human migration patterns have always been complex. Scientists still do not everything for sure. While it is thought that humans stayed at Beringia for an extended period, others believe that successive migration waves crossed the bridge and went south. Sadly, there is not much evidence to support the claims or otherwise. After all, Beringia is lying below the sea right now.
Successive Waves Of Migration
The Native Americans generally support the theory of successive migration waves. They belong to five distinct genetic bands called A, B, C, D, and X. The standstill theory goes that the diversity did not come from various groups from Siberia but from Beringia. It is said that a wave of people stayed at the land bridge so long that they developed a unique gene pool before future generations went to the Americas.
