Scientists have embarked on a mission to discover how different races have been formed since the beginning of ages. The world is nevertheless connected and recent findings come to shed light on the highly debated matter. Human races are a mysterious combo between ancestral DNA that spread across the globe and gave birth to entire communities of people.
Recent statistics show that Native American ancestors have reached the Brave New World in a single migration that started in Siberia almost 23.000 years ago. Later on, as they mingled with other communities with different DNA structures, they differentiated into today’s distinct groups of people. Opinions of experts differentiate, when it comes to the roots of certain communities of inhabitants across the US but most scientists agree the Americans have risen from forefathers who crossed the Bering land and ice bridge that connected the territories known today as Russia and Alaska.
According to the latest research regarding the root DNA of populations, some people in the Brazilian Amazon are distant relatives to indigenous Australians and other Australasians. Researchers still debate the source of this distant ancestry so the results are yet unclear. The connection is very old indeed and attributed to Eurasian migrants to the American lands who sheltered some Australasian ancestry, as scientists reported.
Opinions are nevertheless differentiated, as one group of experts outlines the link between two distinct populations who came from Siberia to settle down in American lands more than 15.000 years ago. On the other hand, analysis could reveal that there was only one founding population from which all indigenous Americans descended, leading to the possibility that the Australasian DNA came a bit later.
The entire data pool was based on comparisons of patterns in the genomes of living individuals from different genetic groups and regions. Ancient skeletons were analyzed as well.
New evidence and more comprehensive analysis states that the first migration, which took place 15.000 years ago, consisted not only of the group known as The First Americans but also of a second group known as Population Y. Population Y could have come before, after or at the same time as the First Americans but carried ancestry much more closely linked to indigenous Australians than to any modern Eurasians or Native Americans. Genetic signature from Australasia appears in Native American Populations indeed, but it is unclear whether Australasians are more close to the root of Native Americans or they appeared later in the definitive development of American DNA.
