The timing of human migration into North America from Asia remains unresolved, but genetic studies tell us that ancestral Native American populations diverged from Asian populations about 36,000 years ago, the same time that Farmer and colleagues found that the Bering Land B...
The Bering Land Bridge was made of land. During the Ice Age, sea levels dropped, exposing land in some areas. The Bering Land Bridge was located where the Bering Strait is now, a shallow area whose water levels dropped and exposed the land bridge during the Ice Age. When did humans cros...
Contrary to previous hypotheses, we found no evidence of steppe-tundra on the land bridge. New accelerator mass spectrometer (AMS) 14 C dates show that much of the land bridge was above sea level and thus available for human and animal migration until as late as 11,000 yr BP....
The Bering Land Bridge theory is important because it is one of the most coherent explanations for human migration to the Americas. Although it is compelling, it is not necessarily the only correct theory for early humans' arrival in the Americas. What is the problem with the Land Bridge theo...

reflecting high territoriality. This runs counter to the trend expected with an overabundant food source. We assume that the combination of the super small size of the home ranges and their exclusivity may be a feature of the island fox land tenure system, which prevents inbreeding and deters ...
