Examples of Clovis and other Paleoindian point forms, markers of archaeological cultures in North America. The Solutrean hypothesis on the peopling of the Americas is the claim that the earliest human migration to the Americas began from Europe during the Solutrean Period, with Europeans traveling along pack ice in the Atlantic Ocean.
According to the authors Green et al. (2010), the observed excess of genetic similarity is best explained by recent gene flow from Neanderthals to modern humans after the migration out of Africa. [11] They estimated the proportion of Neanderthal-derived ancestry to be 1–4% of the Eurasian genome. [11]
Other research supports a migration out of Africa between about 65,000 and 50,000 years ago. [60] [66] [62] The coastal migration between roughly 70,000 and 50,000 years ago is associated with mitochondrial haplogroups M and N, both derivative of L3.
Figure 2. Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia (long chronology, single source model). The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. [1]
Hibernation is a handy biological tool. If you can’t snowbird somewhere warmer in the winter, it’s best just to hunker down, conserve energy, and wait for the spring when resources are more ...
Southern Dispersal migration out of Africa, Proto-Australoid peopling of Oceania. [62] Archaic admixture from Neanderthals in Eurasia, [ 63 ] [ 64 ] from Denisovans in Oceania with trace amounts in Eastern Eurasia, [ 65 ] and from an unspecified African lineage of archaic humans in Sub-Saharan Africa as well as an interbred species of ...
Studies show that the pre-modern migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appeared to have occupied all of Africa about 150,000 years ago; some members of this species moved out of Africa 70,000 years ago (or, according to more recent studies, as early as 125,000 years ago into Asia, [1] [2 ...
