Many skulls from the earliest American Indians, such as the 9,500-year old Kennewick Man, have a head shape that is more similar to that of Eastern Europeans than East Asians.
And then there is the so-called haplotype X mystery, where some tribes of Native Americans today carry a large proportion of the mitochondrial lineage X, which is otherwise only known from Europe. This means that there is a big hole in Asia with no haplotype X, which has made it difficult to reconcile it with the idea that the Native Americans’ ancestors wandered in from Asia.
Together with the discovery of some stone points that resemble spikes that are only known from the Solutré region of France, these puzzles have given rise to some pretty wild theories that the first Americans actually reached America by crossing the Atlantic Ocean.
The Mal’ta find now puts an end to such speculation, and it appears that the researchers can now say with certainty that man entered America through Asia.
Our findings reveal that western Eurasian genetic signatures in modern-day Native Americans derive not only from post-Columbian admixture, as commonly thought, but also from a mixed ancestry of the First Americans.
