The tree of life is a massive framework that maps every living organism, showing how species evolved and branched over ...

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 origin of turtles has always been a bit of a puzzle for scientists who study the evolution of animals. To this day, where they fit in the tree of life remains a highly debated topic. The ...

Long before vertebrates walked on land, millipedes had the place to themselves. Hundreds of millions of years before ...

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 ...

Botanists have mapped the evolutionary relationships between flowering plants using genomic data from more than 9500 species. The newly compiled tree of life will help scientists piece together the ...

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, ...

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.

Most of us can imagine a tree of life; some can even sketch one out. Branches coming off branches coming off branches, each describing a turn in evolutionary history. Over here are the molluscs. Over ...

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 ...
