According to the British newspaper “The Guardian”, the tooth, which was found in one of the caves of the small Asian country, will help to learn more about those known as “Denisovans”, one of the extinct species of the genus. “Homo”.
The cave was first discovered in 2018, and then researchers found a human molar, believed to be from a girl, whose age ranged from 3 1/2 to 8 1/2 years.
Scientists believe that Denisova, a cousin of the Neanderthals, lived in a hot climate in Southeast Asia.
Earlier, scientists in the Russian Siberian region discovered a finger bone belonging to a “Denisova man,” according to the study published in the journal Nature Communications.
The scientists relied on the finger bone and wisdom tooth found in Laos to extract the entire genome of the “Denisovans.”
In 2019, researchers found a jawbone from a “Denisova man” in the Tibetan Plateau region, confirming that this species also lived in China.
With the exception of these limited fossils, only a few traces of Denisovans have survived, with the exception of genes present in the DNA of modern humans.
Since this “mysterious” species has interbred with Homo, remnants of “Denisovans” are still present in today’s population of Southeast Asia.
Traces of this ancient human’s DNA are estimated to be present in 5 percent of the indigenous population of Australia and Papua New Guinea.
Scientists say there was no evidence this ancient human lived in areas outside of the icy Himalayas or the Tibetan Plateau, but the start of research in one of the caves in Laos was a turning point.
