The Study
FUNCTIONAL MORPHOLOGY, STABLE ISOTOPES, AND HUMAN EVOLUTION: A MODEL OF CONSILIENCE
This study is like a computer game that simulates how ancient human relatives might have eaten different foods based on their teeth. It doesn’t prove what they actually ate — it just shows what might make sense in the game. So we can’t say for sure that it’s true in real life.
Analysis score
Maximum 0 for a computational/algorithm study.
Where the score came from
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.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, it helps explain how early human ancestors adapted to eating different foods, especially in tough times.
- 2Thicker enamel helps resist damage when chewing stiff foods.
- 3USOs are tough and abundant, so they could be backup food.
- 4Megadontia likely helped Paranthropus survive when food was scarce.

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.
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.
Primates with thicker tooth enamel tend to eat harder, tougher foods — probably because thicker enamel helps their teeth survive the heavy crunching without cracking.
