Scientists have been digging up clues about the origins of humans for centuries, and remains of human species continue to come to light. But while fossilised skulls and bones are exciting, one of the greatest clues is right under our noses.

Nicola Davis speaks to Peter Ungar, distinguished professor of anthropology and director of environmental dynamics at the University of Arkansas in the US, about his new book Evolution’s Bite. His research into teeth helps us understand exactly what makes teeth so special for archaeologists.
