All species on Earth, both living and extinct, are related. We know this because of a biological tool called the tree of life. This "tree" takes the form of a diagram that maps the relationships ...

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 ...

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 ...

In a groundbreaking discovery, scientists at Trinity College Dublin have identified a "universal thermal performance curve" that governs how all living organisms respond to temperature. This finding ...

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 ...
