The old jaw bone, which was scived from the bottom of the Taiwanese sea, revealed new visions in the appearance and the sweeping geographical group of mysterious human species called Denisovan.
The fossils were discovered by the fishermen wandering on Penghu channel off Taiwan and is believed to be the most completely defined fossil that was genetically identified as Denisovan. The male individual, who lived at least 10,000 years ago, had a strong jaw and very large and very strong molars.
“From the teeth or a small part of the bones, there is the mystery of their appearance,” said Professor Enrico Capnene, from the University of Copenhagen, co -author of the newspaper. Denisovan Discover the jaw in Tibet He began filling this image, adding the latest discovery to evidence of a prominent jaw with huge teeth.
“Now we have a richer picture,” said Cable. “Of course it will be good to have a skull and the rest of the skeleton, but it is a step forward.”
Al -Ahfoura was dated to one of two ice cream, where it is known that the channel was higher than sea level, either between 10,000 and 70,000 years or between 130,000 and 190,000 years.
Scientists were unable to get the DNA from the sample but managed to extract proteins, which can be seen and used to put fossils with confidence on the Denisovan branch of the evolutionary tree.
This discovery reveals an impressive geographical group of ancient species, which lived at the same time – modern humans and humans.
The first Denisovan fossils, which were identified by ancient DNA analysis, came from a cave in Siberia and consisted of a finger and some teeth. Since then, additional discoveries have also shown that Denisovanz has survived incredibly harsh conditions in the high -height plateau, as temperatures can decrease to -30 ° C. In contrast, in Southeast Asia they lived next to the water buffalo in a quiet climate.
“These are the climatic and environmental conditions that are completely different,” Kapleini said. “The cold environment in Siberia, a high rise in Tibet. We cannot infer anything of their cognitive abilities … but they have the ability to adapt to very diverse environments.”
Professor Chris Strenger, a pioneer in human origin research at the London Natural History Museum, who did not participate in the latest research, said the latest discovery as well. Reinforce Denisovan belongs to a group called Homo LongiOr Dragon Man, a full skull was discovered in Harbin in northeastern China.
He said: “It is now clear that Denisovan should have had a broader environmental group of primitive human beings, from cold environments open in North Asia to the semi -tropical forests in Southeast Asia.” “The question for the future will be if we are eventually connected Homo Longi Denisovan, or eventually, call Denisovan Homo Longi“
The results are published in the magazine sciences.
