| Archaeologists have discovered previously unknown human ancestry |
| Prove that the migration and integration of ancient humans has never stopped |
Recently, an international study conducted a genome analysis of ancient human skulls found in a cave in the Wallaceia region (the island region between western Indonesia and Papua New Guinea) and discovered a previously unknown ancient human lineage
.
The research was conducted by Professor Johannes Krause of the Max Planck Institute for Evolutionary Anthropology and the Institute of Human History Sciences in Germany, Cosimo Posth, Professor of the Center for Human Evolution and Paleoenvironment at Senkenberg University of Tübingen, Germany, and Professor of Griffith University in Australia Led by Adam Brumm, it was completed through close cooperation with Indonesian researchers.
The relevant research results were published in Nature on August 25
.
About 50,000 years ago, the first modern people passed through the Vallesia Islands when they traveled from Eurasia to Oceania
.
Archaeological findings show that as early as 47,000 years ago, our human ancestors lived in the Vallesia Islands
One of the most characteristic archaeological finds in the area is the Toalean tombs, dating back 8000 to 1500 years ago
.
Toalean culture is only found in a relatively small area on the southern peninsula of Sulawesi, Indonesia.
The study's first author, Selina Carlhoff, a doctoral student at the Max Planck Institute for Human History Sciences, isolated DNA from the rock bones of the skull
.
"This is a major challenge because these remains have been severely degraded due to the tropical climate,
Genomic analysis showed that this woman was related to the first modern people who traveled from Eurasia to Oceania about 50,000 years ago
.
Like the genomes of the indigenous peoples of New Guinea and Australia, this woman's genome also contains traces of Denisovan DNA
Denisovans are a kind of extinct ancient humans, mainly found in Siberia and Tibet
.
"The fact that their genes were found in women in Leang Panninge cave supports our previous hypothesis that Denisovans once occupied a larger geographic area
By comparing the genome data of hunter-gatherers who lived in the western part of the Vallesian Islands during the same period as this woman, it was found that the hunter-gatherers in the western part of the Vallesian Islands had no traces of Denisovan DNA
.
"The geographic distribution of Denisovans and modern people may overlap in the Vallesian Islands region.
This is likely to be the key place where
However, the female individual found in Leang Panninge cave also carried a large part of the genome from ancient Asians
.
"This is surprising.
In addition, the research team found no evidence that the Leang Panninge cave group belonged to the descendants of today's Wallaceian archipelago population
.
It is unclear what happened to the Toalean culture and its race
