The genomes of most modern humans contain up to 4% Neanderthal DNA. Scientists have now figured out where that exchange happened.
A new study explores the genetic legacy of ancient trysts between Neanderthals and the ancestors of modern humans, with a focus on Western Asia, the region where the first relations may have occurred.
Neanderthals and Denisovans may have endowed modern humans with genetic variants that helped them thrive in new environments.

Regarding the last one: What the hell, Spain?
You might not of thought as certain appearances being primarily from a specific region. Just looking at those with natural blond hair, it appears at least 80% of the population of the nations of Norway, Finland and Sweden are fair-haired - blonds. That Scandinavian region has the great portion compared to any other region. If
In a class discussion format, students are presented with background information about basic human genetics.The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive alleles.

Sometimes we’ve been doing genetic genealogy for so long we forget what it’s like to be new. I’m reminded, sometimes humorously, by some of the questions I receive. When I do DNA Reports for clients, each person receives a form to complete with a few questions designed to give them the opportunity to tell me what…
Contemporary DNA evidence suggests that humans emerged from the interaction of multiple populations living across the continent. A new study in Nature challenges prevailing theories, suggesting that Homo sapiens evolved from multiple diverse populations across Africa, with the earliest detectable
Both the Levantine Corridor and the Horn of Africa route have figured prominently in early hominid migrations from Africa to Eurasia. To gauge the importance of these two African–Asian thoroughfares in the demic movements of modern man, we surveyed the mtDNA control region variation and coding polymorphisms of 739 individuals representing ten African and Middle Eastern populations. Two of these collections, Egypt and Yemen, are geographically close to the Levant and Horn of Africa, respectively. In this analysis, we uncover genetic evidence for the preferential use of the Levantine Corridor in the Upper Paleolithic to Neolithic dispersals of haplogroups H, J*, N1b, and T1, in contrast to an overwhelming preference in favor of the Horn of Africa for the intercontinental expansion of M1 during the Middle to Upper Paleolithic. Furthermore, we also observed a higher frequency of sub-Saharan mtDNA compared to NRY lineages in the Middle Eastern collections, a pattern also seen in previous studies. In short, the results of this study suggest that several migratory episodes of maternal lineages occurred across the African–Asian corridors since the first African exodus of modern Homo sapiens sapiens.
SCIENCE The Clovis culture, which developed in North America about 13,000 years ago from populations originally from eastern Asia, appears to be the ancestor of all Native Americans. Geneticists sequenced DNA of the only known Clovis skeleton and found markers shared with indigenous people from North, Central, and South America. (Reuters) Use our resources to…
