Little is known about the Denisovans, an ancient human species related to Neanderthals, but a new study co-authored by the ºüÀêÊÓƵ’s Bence Viola is helping anthropologists put a finger on the mysterious hominins’ place in human evolution.

Viola, an assistant professor in the department of anthropology, and researchers from France and Russia used a long-lost piece of Denisovan fossil to digitally reconstruct the species’ finger. The result was indistinguishable from modern humans’ slender fingers, and very different from the blunt, stubby digits of the Neanderthals, .

"Until now, all we knew was how their teeth looked," Viola told CBC News, referring to the Denisovans’ massive molars. “All these little pieces allow us to build a picture of who the Denisovans were.â€

The finding suggests that the Denisovans, who were identified less than a decade ago, may have been more similar to humans than previously postulated.
