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, ...

Why most mammals are less colorful than birds, fish, and reptiles?
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.
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!" ...
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, ...

Study reveals the surprising and twisty path our ancestors took to develop an upright stance
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 ...
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 ...
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, ...
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 ...
