The international group of researchers studied the Lady Genom found in Wallace in Indonesia, and revealed previously unknown details about the connections between the ancient groups of people. This is reported in an article published in the journal Nature.
Archaeological finds show that Homo Sapiens ancestors lived on Wallas Islands another 47 thousand years ago. One of the brightest archaeological discoveries in this region is the Tali technological complex, dating from a much later period between 8,000 and 1500 years ago. Among the items manufactured by the people of Talian culture were discovered characteristic stone arrowheads, known as the Maos Isy. Talian culture was discovered only on a relatively small territory on the southern Peninsula of Sulawesi.
Researchers managed to refer to the burial in Leang Panning to this culture. For scientists, it was a serious problem, since the remains were strongly affected by the conditions of the tropical climate. The analysis showed that the man from Leang Panning was a relative of the first modern people who spread to Oceania from Eurasia about 50,000 years ago. Like the genome of the indigenous people of New Guinea and Australia, the man’s genome in Leang Panning contained traces of Denis DNA.
Denisovtsy is an extinct group of archaic people, known primarily by finds in Siberia and Tibet. This confirms the previous hypothesis that Denisovtsy occupied a much greater geographic area. Comparison with the genomic data of hunter-collectors who lived to the west of Wallace at the same time as a person in Leang Panning, did not reveal any traces of Denis DNA.
In the remains detected also revealed the share of DNA from an ancient Asian population. For scientists, it became a surprise because it is known about the spread of a modern person from East Asia to Wallas region, but it happened much later, about 3,500 years ago.
