The origin of turtles has always been a bit of a puzzle for scientists who study the evolution of animals. To this day, where ...

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 ...

A new study unveils the most comprehensive understanding of the evolutionary history of flowering plants to date. The research analyzed 1.8 billion letters of genetic code from more than 9,500 species ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

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, ...

Evolution is perhaps the most extraordinary story ever told—a tale spanning billions of years that connects every living thing on Earth through an intricate web of shared ancestry. From the tiniest ...

How do scientists study and classify life-forms? How can we understand the complex evolutionary connections between living organisms? Woese's breakthrough was momentous for at least three reasons.

In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry.
