The study of the remains provided the first clue that the mixing between early humans in Indonesia and Siberia occurred earlier than previously thought.
The genetic traces of a young woman who died 7,000 years ago provide the first clue that the mixing between early humans in Indonesia and humans in distant Siberia occurred much earlier than previously thought.
A study published in the scientific journal Nature in August, after analyzing the deoxyribonucleic acid (DNA) or genetic fingerprints of women who held ritual funerals in Indonesian caves, could change theories about early human migration in Asia, according to Reuters , Reported these findings on Wednesday.
“The Wallace area may be the intersection of the two human species between the Denisovans and the early Homo sapiens,” said Archaeologist Baslan Burhan of Griffith University in Australia.
Burhan was one of the scientists involved in the study. He was referring to the Indonesian region including South Sulawesi, where bodies were found in the Leang Pannige caves, with rocks buried in his hands and pelvis.
The Denisovans are a group of ancient humans named after a cave in Siberia, where their remains were first discovered in 2010. Scientists know very little about them, and even the details of their appearance are not known.
DNA from Besse, just as researchers named young women in Indonesia, using the term newborn girl in the language of the Bugis region, is one of the few well-preserved specimens found in the tropics.
Scientists say this shows that although she is a descendant of the Austronesian common in Southeast Asia and Oceania, she also has genetic traces of the Denisovan.
They said in the paper: “Genetic analysis shows that this pre-Neolithic forager…has most of the genetic drift and morphological similarity with today’s Papuans and Australian indigenous groups.”
The remains are currently stored in a university in Makassar, South Sulawesi.

Besse’s DNA changed theories about this pattern of early human migration, and may also provide insights into the origins of Papuans and Aboriginal Australians who shared Denisovan’s DNA.
“Theories about immigration will change because theories about race will also change,” said Iwan Sumantri, a lecturer at Hasanuddin University in South Sulawesi, who also participated in the project.
He added that the remains of Beth are the first sign of Denisovans among the oldest ethnic group of Austronesians in Indonesia.
“Now try to imagine how they spread and distribute genes to Indonesia,” Sumantri said.
