The archeology earth is abuzz today with tidings ofthe first Denisovan fossil bump outside of Siberia . The 160,000 - year - old jawbone was uncovered by a Buddhistic monk in a Chinese cave nigh 40 years ago — an facet of this story that ’s as intriguing as it is frustrating .
To quickly recapitulate this breaking news , a partial jaw pearl found in Baishiya Karst Cave on the Tibetan Plateau in Xiahe , China , has been identified as belonging to the mysterious Denisovan hominins , a sister species to the Neanderthals that went extinct about 50,000 years ago .

It ’s the first time that a Denisovan fossil has been found outside of Siberia , or even outside of Denisova Cave for that matter . The bearing of the fossil in the high - EL Tibetan Plateau finally explains why Denisovans had a transmitted variant associated with a resistance to altitude sickness . It also shows that Denisovans had retained some primitive forcible features , such as robust molars , and that they had traveled across Asia . In all , a very important archaeologic discovery , thedetailsof which were published today in Nature .
That said , the Denisovan jowl was not discovered by the authors of the new paper , a quislingism between the Max Planck Institute for Evolutionary Anthropology ( MPI - EA ) and Lanzhou University . Rather , the fossil was find in 1980 by an anon. Buddhist monk who stumble upon the keepsake after venturing into the cave to pray and contemplate , according to Jean - Jacques Hublin , an MPI - EA archaeologist and the lead writer of the new study .
This account could ’ve finish right there owing to a local custom . As Hublin pointed out , multitude from the nearby town of Xiahe used to grind the “ holy bones ” collected from this cave to produce medicament . The monk , however , resolve to hand the fossil over to the Sixth Gung - Thang Living Buddha , who in twist passed it on to scientists of Lanzhou University . It was n’t until 2010 that a research team from the Lanzhou University was allowed to enquire Baishiya Karst Cave , which is a protect religious sanctuary , pronounce Hublin . Researchers from MPI - EA joined the investigating in 2016 , a quislingism that eventually chair to the identification of the jawbone as belonging to a young Denisovan soul who occupied the cave some 160,000 years ago .

The discovery of this now - famous fossil by the monk is an interesting tale , but it presents some serious obstruction for the scientists .
As Hublin maneuver out at a press conference earlier this week , the relic was found “ outside of an archaeologic context . ” What he meant by this is that the lower jaw was not document in its original view in the cave . Consequently , archeologist ca n’t be sure about its original location , so it ’ll be difficult in the future to associate it with potential items of importance , such as stone peter , butchered brute bones , or even other yet - to - be discovered Denisovan bones . As Hublin pointed out , this will present a awful challenge for future archaeologists — assuming , of course , that other fogey or artefact will be find in Baishiya Karst Cave . gratefully , as Hublin explained to Gizmodo , a bed of carbonite incrustation on the jawbone allowed his squad to date the fossil , which means they might be able to link it with a particular stratigraphic layer .
Another problem with the nature of this breakthrough is the possibility that the mandible was fork up to the cave by the monk or someone else .

“ In possibility , yes , ” Hublin told Gizmodo when asked about this opening . He say many of the Xiahe local anesthetic remember the breakthrough made by the monk nearly four decades ago , and that it would be “ weird ” for a monk to find a mandible somewhere else and then take to have retrieve it in the Baishiya Karst Cave . During Monday ’s press conference , Dongju Zhang , an archaeologist at Lanzhou University and a atomic number 27 - author of the new study , enunciate , “ I do n’t consider the local multitude would lie down about this . ”
Hublin tell further archaeologic investigation in the cave will only serve to add further backing to the call that the submaxilla originated from this peculiar website . At least , once license are received from the local governance to explore this spiritual sanctuary — a task that Hublin aver wo n’t be soft .
