Research on the remains first indicates that the mixing between early humans in Indonesia and Siberia occurred earlier than previously thought.
The genetic marker on the body of a young woman who died 7,000 years ago was the first indication that the mixing between the early people of Indonesia and people from distant Siberia occurred much earlier than previously thought.
After analyzing dexiribonucleic acid (DNA), or genetic fingerprint, of a woman buried religiously in a cave in Indonesia, a study published in the scientific journal Nature in August could transform theories about early human migration to Asia, according to Reuters news agency on Wednesday.
“There is a possibility that the Walesia region could be a meeting place for two human species,” said Basran Burhan, an archaeologist at Griffith University in Australia.
Burhan, a scientist who participated in the study, was referring to the region of Indonesia that included South Sulawesi, where the body was found with stones and buried in the pelvis, in the cave complex in Leung Panig.
The Denisovans were a group of ancient people named after a cave in Siberia, where their remains were first identified in 2010.
Based on DNA, researchers used the term for a newborn baby in the regional Bugis language as the name of an Indonesian young woman, one of the few well-preserved specimens found in the tropics.
It showed that when he came from the Austronesian population to Southeast Asia and Oceania, he also had the Denisovan genetic mark, scientists said.
“Genetic analysis shows that this pre-Neolithic Fraser … has most of the genetic drift and morphological similarities with the current Papuan and Indigenous Australian group,” they said in the paper.
The remains are currently preserved at a university in the town of Makassar in South Sulawesi.
Until recently, scientists thought that North Asian people, such as the Denisovans, came to Southeast Asia only 3,500 years ago.
Bases’ DNA changes theories about such patterns of early human migration and may also give an idea of the origin of the Papuan and Indigenous Australian peoples who share the Denisovan DNA.
Ivan Sumantri, a lecturer at Hassanuddin University in South Sulawesi involved in the project, said, “Theories about immigration will change, because theories about race will also change.”
The remains of the base provide the first sign of the Denisovans among the Austronesians, the oldest ethnic group in Indonesia.
“Now try to imagine how they spread and distribute their genes to reach Indonesia,” Sumantri said.
