Properly deciphering the branching pathways of evolution could unlock the history of every component of natural biology.

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have evolved testicles of all different sizes. In almost all these separate cases, ...

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 ...

Artificial Christmas trees have been around since the 19th century, if not earlier. Trees made of dyed feathers originated in Germany and were introduced to the U.S. by the early 20th century. The mid ...

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, ...

A study has found evidence that the evolution of tree roots over 300 million years ago triggered mass extinction events through the same chemical processes created by pollution in modern oceans and ...

Researchers have run through near-perfect fossils of the world's first gliding reptile with a fine-toothed comb and untangled hitherto unknown facets to discover it was a change in tree canopy which ...
