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, ...

Newly discovered fossils, belonging to the mammal-precursor species Brasilodon quadrangularis and Riograndia guaibensis, offer critical insights into the development of the mammalian jaw and middle ...

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 ...

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

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 ...

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, ...

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

Twins have been rare in human history and for that reason can seem special. Many cultures associate twins with health and vitality, while others see them as a philosophical reminder of the duality of ...
