A research team, led by scientists at the University of York, mapped the family tree of the ferocious ambush-predators and their extinct relatives known as Pseudosuchia. They then compared this with ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

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 three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time ...

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.
