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, ...

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 ...

Highly valued economically, ecologically and culturally, the white oak (Quercus alba) is a keystone forest species and is one of the most abundant trees across much of eastern North America. It also ...

The study found that bird species who nest in tree cavities have independently evolved heightened aggression across lineages, particularly in females. Scientists have long wondered whether evolution ...

In a world where evolutionary biology often gets boiled down to simplistic hierarchies of "primitive" and "advanced" species, a new book by University of Maryland, Baltimore County (UMBC) biologist ...

Scientists have identified the genetic changes that helped tree-dwelling snakes to evolve longer tails across multiple ...

The largest-ever study of bird genomes has produced a remarkably clear picture of the bird family tree. Published in the journal Nature today, our study shows that most of the modern groups of birds ...
