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 ...

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

A diverse group of lizards known as the social skinks is helping scientists answer questions about some of the fundamental workings of evolution. Skinks are a large group of lizards that typically ...

Almost every plant we eat has a flower, and flowering plants populate every corner of the planet. But many questions remain about how and when this vast group emerged throughout the history of life on ...

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 ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

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.
