The new research is the first to look back at early mammals in full color. Using advanced fossil imaging methods and a thorough examination of the pigment-producing cells present in living mammals, ...

A new study shows cultural evolution helped humans expand across Earth far faster than genetic change alone could achieve.

Around 11 million years ago, a cooling climate fragmented warm, humid forests in Africa, Asia, and Europe, giving rise to savannas. Many mammals evolved to take advantage of these wide-open spaces, ...

Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every ...

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 ...

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 ...

Mammals, including humans, stand out with their distinctively upright posture, a key trait that fueled their spectacular evolutionary success. Yet, the earliest known ancestors of modern mammals more ...

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 ...

Mammals, including humans, stand out with their distinctively upright posture, a key trait that fueled their spectacular evolutionary success. Yet, the earliest known ancestors of modern mammals more ...

Men have nipples, mammary glands and the hormones required, but the ability for male lactation rarely turns on. Here’s why evolution mostly suppresses it.

South American mammals present a fascinating case study in evolutionary biology, shaped by a dynamic interplay of palaeoenvironmental shifts, adaptive radiations and biogeographic isolation. The ...
