The onset of the Last Glacial Maximum after 30,000 years BP saw the expansion of alpine glaciers and continental ice sheets that blocked migration routes out of Beringia.

By 21,000 years BP, and possibly thousands of years earlier, the Cordilleran and Laurentide ice sheets coalesced east of the Rocky Mountains, closing off a potential migration route into the center of North America.

Models of molecular evolution rates are used to estimate the ages at which Native American DNA lineages branched off from their parent lineages in Asia and to deduce the ages of demographic events.

One model based on Native American mt DNA Haplotypes (Figure 2) proposes that migration into Beringia occurred between 30k and 25k cal years BP, with migration into the Americas occurring around 10k to 15k years after isolation of the small founding population.

Available scientific evidence indicates that modern humans emerged from Africa over 100,000 years ago, yet did not arrive in the Americas until less than 20,000 years ago.Modern biochemical techniques, as well as the accumulation of archaeological and geological evidence, have shed progressively more light on the subject; however, significant questions remain unresolved.During the Wisconsin Glaciation, varying portions of the Earth's water were stored as glacier ice.The archeological evidence suggests that the Paleo-Indians' first dispersal into the Americas occurred near the end of the last glacial period or, more specifically, what is known as the Last Glacial Maximum (LGM), around 16,500–13,000 years ago.The settlement of the Americas from Asia is of intense interest to archaeologists and anthropologists.
