New research out of the University of Otago that looked at over 20,000 teeth may just debunk what we know about our ancestors' eating habits.
The study looked at the chipping patterns in the teeth of fossils and living primates, to find out whether they were likely to have eaten soft or hard foods.
Researcher Dr Ian Towle, an Otago biological anthropologist, explains the findings to Jesse.
