A tiny tooth can disappear between your fingertips without much effort. Yet some of the earliest clues to our own ...

Without it, teeth this small can slip past standard collecting. “This discovery helps fill a gap in understanding the geography and evolution of our earliest primate relatives after dinosaur ...

Tiny fossil teeth discovered in Colorado reveal new clues about Purgatorius, the earliest known primate relative, reshaping ...

Fossils smaller than a fingertip are reshaping what scientists thought they knew about how primate relatives spread after the asteroid impact.

What we did To test these assumptions, we analyzed more than 500 teeth from 27 primate species, both extinct and living. The sample included gorillas, orangutans, macaques, colobus monkeys, fossil ...

Tooth fossils hint that size came before specialised feeding in early Asian mammals. The story of how mammals rose to ...

A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larger brain size—while ...
