Ever since Darwin, biologists have been drawing trees to attempt to capture the complexity of evolution in various domains.

Little is known about the early history of lizards, snakes and their kin. New fossil discoveries reveal a complex ...

A recent study dramatically pushes back the date for the emergence of our species, though some researchers call for further ...

Professor Emily Jane McTavish and colleagues at the Cornell Lab of Ornithology have mapped the evolution of every known bird species. They created a complete evolutionary tree of bird species by ...

In a new article published in Frontiers in Bioinformatics, biologists Dr. Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that ...

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 ...

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 ...

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 ...

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 ...

WASHINGTON (Reuters) - Since first appearing during the age of dinosaurs, snakes have authored an evolutionary success story - slithering into almost every habitat on Earth, from oceans to tree tops.

Why it's awesome: The hoatzin is often regarded as one of the world's strangest birds. Hatchlings are born with clawed wings — a rare, prehistoric trait — and adults give off a strong, unpleasant ...
