A monkey descending a tree trunk often keeps its head up, moving almost like a cautious climber backing down a ladder.

A new study explains how climbing down trees helped shape upright posture in early primates and changed the course of evolution.

Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their ...

“A 62-million-year-old skeleton of this quality and completeness offers novel insights into mixodectids, including a much clearer picture of their evolutionary relationships,” study co-author and Yale ...

A new study led by Michigan State University researcher Peter Williams sheds light on the profound influence of deep geographic isolation on the evolution of mammals. Published in Nature ...

If textbooks ever made you believe mammals like humans, cats, and kangaroos first evolved somewhere up north, think again. A remarkable discovery from Australia has flipped our understanding of mammal ...

Vertical locomotion in arboreal mammals is shaped by a complex interplay of body mass, limb proportions, grasping abilities, and head mass, and primates use distinct upright postures during descents.

More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research has revealed. More mammals were living on the ground several ...

A new look at a fossil mammal with powerful front legs for digging is clearing up questions about the origin of a group of strange and scaly modern-day creatures called pangolins. First excavated in ...
