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 ...

Tree thinking is a pedagogical approach that emphasises the interpretation and construction of phylogenetic trees to elucidate evolutionary relationships. In the context of evolutionary biology ...

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

An international team has been able to reconstruct the evolutionary tree of a major group of snakes, Elapoidea, that has proved to be a significant step towards the construction of a complete Tree of ...

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 ...

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 ...

Revolutionary fossil evidence from Ethiopia is challenging decades of scientific consensus about human origins. New discoveries suggest that the famous Lucy fossil, long considered a direct ancestor ...

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, ...
