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, ...

Most mammals wear coats of brown, black, and gray, while parrots flash brilliant reds, reef fish shimmer in electric blue, and chameleons shift between greens and golds. This disparity is not random.

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 ...

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, ...

From whale songs to lion roars, animals have evolved to stretch their voices across distances so that friends—and sometimes foes—can hear them. Each sound is coded with messages like "Come here!" ...

Take a mama salmon, for example. It lays thousands of eggs at a time which the males fertilize thoroughly. The salmon packs each egg with more yolk compared to an urchin, that means more proteins, ...

Evolution of life histories : theory and patterns from mammals / Mark S. Boyce -- Geographic variation in life history traits of the Hispid cotton rat (Sigmodon hispidus) / Guy N. Cameron and Polley A ...

The mammalian olfactory system has evolved a remarkable complexity, integrating specialisations in the nasal architecture that support diverse ecological roles. Central to this system are the turbinal ...
