Prehistoire There are currently several models of the peopling process differing with respect to timing, routes, and affiliation with modern (and ancient) populations in asia and the americas . one perspective that has become prominent in the last decade is of an early entry (~25,000 to 15,000 years ago) into the americas via a pacific coastal migration. By the way, at monday’s press conference, the authors acknowledged that beringia and the kelp highway are not the only two models for the peopling of the americas. a few others are bandied about, most typically in sketchy videos that are light on sourcing. there has been speculation, for example, that oceanic populations sailed. Here is the evidence for three theories explaining how the first humans arrived in america: the land bridge theory, the trans pacific migration theory and the controversial solutrean hypothesis. For decades, that time frame was widely considered to mark the earliest possible date of initial entry, until data from sites more than 13,000 years old in north and south america, first reported.

A subsequent theory, known as the “kelp highway,” came closer to the mark: as the massive ice sheets covering western north america retreated, the first humans arrived on the continent not.
