Fossils are rare because their formation and discovery depend on chains of ecological and geological events that occur over deep time. Only a small fraction of the primates that have ever lived has ...

Adaptation and behavior in the primate fossil record / Callum F. Ross ... [et al.] -- Functional morphology and in vivo bone strain patterns in the craniofacial region of primates: beware of ...

Primates—the group of animals that includes monkeys, apes and humans—first evolved in cold, seasonal climates around 66 million years ago, not in the warm tropical forests scientists previously ...

For decades, paleoanthropologists pointed to tiny grooves between ancient hominin teeth as proof that early humans and ...

Great apes began to diverge from other primates about 25 million years ago, according to eastern African fossil records. Though it would take another 20 million or so years for upright-walking ...

Analysis of fossils found in the far north of Canada has revealed that two previously unknown species of ancient near-primates lived above the Arctic Circle some 52 million years ago, according to new ...

That places the fossils about 656,000 to 560,000 years after the boundary. A broader cast of “almost primates” Purgatorius matters because it sits near the base of a larger family tree. The paper ...

We found these grooves also appear naturally in wild primates, with little support for tooth-picking as the cause. Even more striking, in more than 500 wild primates, across 27 species both living and ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...
