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

It seems that the evolutionary tree of life looks more like a giant swirling lollipop. Scientists have assembled the largest and most accurate timeline of life on Earth containing more than 50,000 ...

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 ...

There’s a whole new branch on the evolutionary tree of life, made up entirely of predators who “nibble their prey to death”. These are not the fearsome species we normally associate with predation, ...

A team of scientists led by the University of Bristol has provided new insights into the origins of the Archaea, the group of simple cellular organisms that are the ancestors of all complex life. The ...

A popular model of evolution concludes that it was incredibly unlikely for humanity to evolve on Earth, and that extraterrestrial intelligence is vanishingly rare. But as experts on the entangled ...

Human testicles are much smaller, in proportion, to some of our primate cousins. Evolution can tell us why. But the size of other body parts is a little bit more of a mystery. The human body is a ...

There are two million different species in the world - plants, bacteria, animals, everything. And what scientists call them has happened haphazardly - so for example if you say Anthrax, you could be ...
