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, ...

A glimmer of hope has emerged for Britain's beloved ash trees. According to a new study published in Science, some wild ash ...

An international team has remapped the evolutionary relationships of butterflies found across South and Central America to help monitor and support biodiversity.

Each branch on the tree signifies the splitting of a common ancestor into two or more descendants — a process powered by natural selection. Take Eukarya, for example.

Ben Crair on the hoatzin, the bird that is seemingly defying the concept behind the tree of life; B10K, a research group that is trying to sequence the genome of every species of bird; and DNA ...

Researchers from the Smithsonian’s National Museum of Natural History have identified the oldest decisive evidence of humans’ close evolutionary relatives butchering and likely eating one another. In ...

They are a major factor in evolution.” However, by using an evolutionary model that allows for budding instead of splitting, the scientists got a picture that much more closely matched the fossil ...

The story of evolution tells us how, starting from simple beginnings, each species was built – when each of the components that make a living creature was added to its blueprint. If we climb the ...
