Some ancient human relatives had huge teeth with extra-thick enamel. This might have helped them chew tough underground plants when their usual food was hard to find.

Big, thick teeth in some ancient human relatives might have made it easier to chew tough foods like roots and tubers when their usual food wasn't available.
Big teeth in Paranthropus might have helped them survive tough times by letting them eat hard backup foods when their usual meals weren’t available — explaining why their teeth look worn in surprising ways.
Primates with thicker tooth enamel tend to eat harder, tougher foods — probably because thicker enamel helps their teeth survive the heavy crunching without cracking.
