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 ...

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 ...

Butterflies closer to the equator have been shown to evolve shared wing patterns faster than their relatives at higher latitudes. That gradient reframes tropical diversity as an active process, shaped ...

The Cornell Lab of Ornithology today announced the release of a new online tool for studying biodiversity and the ...

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 ...

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 ...

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 ...

Some butterflies can smell others of the same species, allowing them to identify each other in areas where multiple species all look the same, new research finds. A large international team has ...

A groundbreaking study has traced the 66-million-year evolutionary history of primates and overturned conventional thought that our ancestors originally inhabited warm tropical forests. Using advanced ...
