Imagine that a biological anthropologist 10,000 years in the future is examining our fossil remains. The anthropologist notices that humans have broad incisors and molars with rounded cusps. How do you think the anthropologist would interpret these traits---what diet would these traits indicate

They were frugivores

Explanation:

Frugivores are animals that mainly eat raw fruits, vegetables, roots, seeds, shoots, etc. Frugivores need to eat diverse fruits and succulent fruit-like vegetables to fulfill their nutritional requirements, although they can supplement this diet with flowers, nectar, small insects, etc. Among their adaptations for fruit consumption, frugivore teeth are clearly distinct, having broad incisors to peel tough fruit rinds. Moreover, these animals generally have long small intestines to digest the fruit.
