Ancient Teeth Just Changed Human History

Turns out, those ancient teeth we thought we had all figured out? Not so simple! Scientists cracked open the secrets of Paranthropus robustus tooth enamel and found protein clues that suggest there might have been more than one species hanging out in prehistoric Africa. Plus, they used these proteins to finally sort out which fossils were male or female—turns out, tooth size alone was super misleading. Human evolution just got a whole lot messier (and way more interesting)! #HumanEvolution #FossilFinds #ScienceNews #Science
