The sprawling-upright transition across mammal evolution, showing changes in posture and limb bone shape. The transition from sprawling (reptile-like) to more upright (parasagittal) posture and ...

The shift from lizard-like sprawl to upright walking in mammals wasn’t a smooth climb up the evolutionary ladder. Instead, it was a messy saga full of unexpected detours. Using new bone-mapping tech, ...

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

For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition—from ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team showed that a group of highly divergent mammals known as Afrotheria and distantly ...

One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing. The middle ear of mammals, with an eardrum and several small bones, allows us to ...
