Direct genetic traces of the earliest Native Americans have been identified for the first time in a new study. The genetic evidence suggests that people may have entered the continent in a single migratory wave, perhaps arriving more than 20,000 years ago.
Early humans seem to have recognised the dangers of inbreeding at least 34,000 years ago, and developed surprisingly sophisticated social and mating networks to avoid it, new research has found.
Unprecedented study of Aboriginal Australians points to one shared Out of Africa migration for modern humans21 Sep 2016
The first significant investigation into the genomics of Aboriginal Australians has uncovered several major findings about early human populations. These include evidence of a single “Out of Africa” migration event, and of a previously unidentified, “ghost-like” population spread which provided a basis for the modern Aboriginal cultural landscape.
Using ancient DNA, researchers have created a unique picture of how a prehistoric migration route evolved over thousands of years – revealing that it could not have been used by the first people to enter the Americas, as traditionally thought.
New research dates plague back to the early Bronze Age, showing it had been endemic in humans across Eurasia for millennia prior to first recorded global outbreak, and that ancestral plague mutated into its bubonic, flea-borne form between the 2nd and 1st millennium BC.
