The tree, the most complete of its kind, shows the evolutionary timescale of the whole order of primates, including monkeys, apes, lemurs, lorises, and galagos.

Reconstructing an evolutionary tree allows scientists to ask questions about how and why primates moved and changed. They can cross-reference information such as the climate that would have existed at ...

With a more complete tree in hand, scientists can ask deeper questions about primate evolution. One question they explored is whether certain primate groups evolve faster than others.

Most people imagine our early primate ancestors swinging through lush tropical forests. But new research shows that they were ...

A new dataset of genetic information collected from 233 primate species, the largest and most complete of its kind, promises to yield insights into primates’ evolutionary biology and how genetics ...

We have been researching the evolution of primate litter size – how many babies grow during each pregnancy – for the past several years. To study mammal evolution and reproductive life history, we use ...

Researchers have found a link between long thumbs and big brains, suggesting the two features evolved together ...

Further back in evolution, two babies at once was the norm. Our ancient primate ancestors gave birth to twins. So, when did this evolutionary change in primate litter size occur? The switch to ...

Study reveals a correlation between thumb and brain size in primates, indicating that as thumb dexterity improved, brain size ...
