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 ...

From ancient algae to domestic dogs, scientists are uncovering surprising twists in evolution’s story. New research challenges long-held ideas about how species form, adapt, and branch off. These ...

An international team of scientists has created the largest and most detailed bird family tree ever, spanning 93 million years and representing 92% of bird families species, using cutting-edge ...

Phylogenetic tree analysis reconstructs the branching relationships among organisms or genes, revealing their shared ancestry and divergence over time. These tree structures are central to ...

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 ...
