It suggests that manual dexterity and brain evolution are connected across the entire primate lineage, from lemurs to humans. Notably, the correlation held even when human data were excluded, ...

Longer thumbs mean bigger brains and this is “pivotal” to human evolution, research has found. Scientists studied 94 fossils and living animals to understand how our ancestors developed their gripping ...

Primate evolution claim challenged An analysis of 37 million year old primate fossils is fueling a debate over the existence of an evolutionary link between lemur-like and monkey-like primates -- a ...

A large comparative study of primate teeth shows that grooves once linked to ancient human tooth-picking can form naturally, while some common modern dental problems appear uniquely human.

What events led to differences between humans and other primates? What changes throughout evolution underlie such a dramatic shift in how we socialize and process information? Although somewhat ...

Primate locomotion and evolution encompass the diverse adaptations that have enabled primates to negotiate complex arboreal environments. Throughout their evolutionary history, primates have acquired ...

Microbes supporting the production of more metabolic energy could be key to the evolution of large brains First study to show gut microbes from different animal species shape variations in their ...
