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 ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

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 ...

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 ...

The scientists examined the lineages of two groups of bivalves—marine invertebrates that include clams, oysters, mussels, and scallops—that successfully inhabit the deep sea. They found that some ...

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 ...

We humans have long viewed ourselves as the pinnacle of evolution. People label other species as “primitive” or “ancient” and use terms like “higher” and “lower” animals. This anthropocentric ...

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 shows the “upside-down trees” originated in Madagascar and then caught a ride on ocean currents to reach mainland Africa and Australia. By Rachel Nuwer Baobabs are one of the most ...

Fri, May 2, 2025 at 12:00 PM UTC Those many millions of years have given birds time to evolve into some 11,000 species, and keeping track of all those species—not to mention their evolutionary history ...
