Oldest DNA extracted from Neanderthal who fell down sinkhole 150,000 years ago, starved to death, fused with walls
It was a gruesome death that is the stuff of most people's nightmares. Now scientists have identified the unfortunate individual whose bones were found fused to the walls of a cave in Lamalunga, near Altamura, in southern Italy.
Using analysis of DNA extracted from the bones sticking out from the limestone rock, researchers have found he was a Neanderthal who fell down a sinkhole around 150,000 years ago. Genetic analysis of the bones (above) of 'Altamura Man', found entombed in limestone in a cave in Altamura, Italy, has revealed that they belong to a Neanderthal who fell into the cave 128,000 to 187,000 years ago
Wedged in the narrow space and probably badly injured, he is thought to have starved to death.
Over the thousands of years that followed, the body decayed and the remaining bones gradually became incorporated into the stalactites left behind by water dribbling down the cave walls.
The DNA is the oldest to ever be extracted from a Neanderthal and the researchers now hope to further analyse the genetic information from the skeleton.
First discovered in 1993, the skeleton - nicknamed 'Altamura Man' - has provoked debate among anthropologists partly due to the difficulties in studying the skeleton as it had become part of the cave walls. Examination of those bones that were exposed suggested they belonged to an adult male.
However, few could agree on whether the skeleton belonged to a Neanderthal or a modern human, or how long it had been down there.
But after taking a tiny part of the skeleton's shoulder bone, researchers at the Sapienza University of Rome, University of Firenze and Newcastle University have been able to answer the questions.
They found mitochondrial DNA they extracted from the shoulder bone matched that of other Neanderthal skeletons. Uranium-thorium dating techniques has also revealed that the skeleton appeared there between 172,000 and 130,000 years ago, during a period when ice sheets were expanding significantly from out of Antarctica and Greenland.
Giorgio Manzi, one of the palaeoanthropologists leading the study from the Sapienza University of Rome, said: 'Altamura Man is an incredible treasure for the Alta Murgia territory. 'We hope that this fossil skeleton will become a key for a virtuous combination of scientific research, protection of our heritage and its promotion and development.'
The Altamura Neanderthal is thought to have come to rest in its unusual tomb after an adult male fell down a sinkhole into a limestone karst system. Wedged in the narrow rocks, he were unable to move and probably starved to death. However, it also means no predators were able to reach his body.
Over time, his bones fell where had died, with some still lodged in the cave gap and were eventually absorbed into the walls of the cave itself. Cave explorers then stumbled across the bones in 1993.
Researchers eventually obtained permission to take a fragment of the shoulder bone in 2009 and have spent six years studying it. Writing in the , the research team said: 'Even though a number of Neanderthal traits can be seen—particularly in the face and in the occipital bone—there are features that distinguish this specimen from the more typical morphology of, such as the shape of the brow ridges, the relative dimension of the mastoids, and the general architecture of the cranial vault.
'Overall, our results concur in indicating that it belongs to , with some phenetic peculiarities that appear consistent with a chronology ranging from 172 ± 15 ka to 130.1 ± 1.9 ka.
'Thus, the skeleton from Altamura represents the most ancient Neanderthal from which endogenous DNA has ever been extracted.'
If they manage to sequence the DNA, they hope it might reveal new details about the evolution of hominids in general and the early history of the Neanderthal. It could also help shed new light on their relationship with modern humans analysis of other Neanderthal DNA has shown they interbred with our own species.
Recent research has shown that Neanderthals suffered from a wide range of diseases that still plague us today - and this may be what killed them off. They have found evidence that suggests our prehistoric cousins would have been infected by diseases such as tuberculosis, typhoid, whooping cough, encephalitis and the common cold. But anthropologists from Cambridge University and Oxford Brookes University say that new diseases carried by modern humans may have led to the downfall of Neanderthals.
