Denisovan Leg Bones Reveal Remarkable Body Size for Ancient Humans
Two leg bones dredged from the Taiwan Strait suggest that at least some Denisovans were exceptionally tall, powerfully built, and reliant on terrestrial meat. The specimens, named Penghu 2 and Penghu 3, are a partial right femur and a right tibia. Ancient proteins recovered from both bones include a Denisovan-associated collagen variant, while broader protein comparisons place them alongside the previously identified Penghu mandible and a Denisovan from Denisova Cave. That molecular evidence is significant because Denisovan anatomy has previously been known mainly from a skull, jaws, teeth, a finger bone, and other fragments.
The findings, are yet to be peer reviewed, but have been released in two new bioRxiv preprints and covered by Science. They offer one of the clearest glimpses yet of the bodies and daily lives of this enigmatic human relative.
A long-awaited look at Denisovan bodies
The researchers estimate that Penghu 2 belonged to an individual about 180 centimeters tall and weighing roughly 83 kilograms, while Penghu 3 came from someone around 190 centimeters tall and weighing about 91 kilograms. Those estimates would have placed the two individuals above the average stature reported for Neanderthals and Late Pleistocene humans in the region. As archaeologist Ben Marwick told Science, “They were very tall!”
