“A 62-million-year-old skeleton of this quality and completeness offers novel insights into mixodectids, including a much clearer picture of their evolutionary relationships,” study co-author and Yale ...

Properly deciphering the branching pathways of evolution could unlock the history of every component of natural biology.

Poposaurus comes from a group of extinct relatives of the crocodile known as Poposauroidea. Crocodiles and birds share an evolutionary heritage with dinosaurs and pterosaurs, despite there being ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have evolved testicles of all different sizes. In almost all these separate cases, ...

Molecular evolutionary trees show that elephant shrews are more closely related to elephants, than they are to shrews. Credit: Danny Ye New research led by scientists at the Milner Centre for ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

Mammals keep evolving into anteaters, eating only ants and termites, at least 12 times since the age the dinosaurs.

An updated evolutionary model shows that living systems evolve in a split-and-hit-the-gas dynamic, where new lineages appear in sudden bursts rather than during a long marathon of gradual changes.

Human evolution might be more "bizarre" than we once thought, according to a new study. In the past, scientists believed that hominin evolution was largely driven by changes in climate. But now, ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...
