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]
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 ...
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

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.
The second wave of migration took a more northerly course, splitting somewhere in the area around what is now called Syria to sweep to interior Asia, where it split several more times in Central Asia, north of Afghanistan. The lineages that flowed into Central Asia carry M9 (Haplogroup K (Y-DNA)). Other markers were added after the migration ...
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.
Further research has shown that the back-migration into the region was a complex process, identifying multiple origins for the Eurasian component in Northeast African groups today. [ 20 ] [ 21 ] A report in November 2015 on a 4,500-year-old Ethiopian genome [ 22 ] [ 23 ] had originally overestimated the genetic influence of the Eurasian ...
[28] [25] According to Pamjav et al. (2019) and Fóthi et al. (2020), the distribution of ancestral subclades like of I-CTS10228 among contemporary carriers indicates a rapid expansion from Southeastern Poland, is mainly related to the Slavs and their medieval migration, and the "largest demographic explosion occurred in the Balkans".
