The more we learn, the more questions emerge. New research methods are revealing fascinating information about how humans lived centuries ago…

In 2010, scientists discovered a new kind of human by sequencing DNA from a girl’s pinky finger found in Denisova Cave in Siberia. Ever since, researchers have wondered when the girl lived, and if her people, called Denisovans, lingered in the cave or just passed through. But the elusive Denisovans left almost no fossil record—only that bit of bone and a handful of teeth—and they came from a site that was notoriously difficult to date.

Now, state-of-the-art DNA analysis on the Denisovan molars and new dates on cave material show that Denisovans occupied the cave surprisingly early and came back repeatedly. The data suggest that the girl lived at least 50,000 years ago and that two other Denisovan individuals died in the cave at least 110,000 years ago and perhaps as early as 170,000 years ago, according to two talks here last week at the meeting of the European Society for the study of Human Evolution. Although the new age estimates have wide margins of error, they help solidify our murky view of Denisovans and …read more
