Researchers at the University of Bristol have traced the genetic changes that allowed animals to colonize land not once but ...

Nearly 30 years ago, a research vessel off the southeast coast of Australia dragged up samples of the sea floor from depths of 400m and 1000m. Hidden away within the samples were a few unexpected gems ...

Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet ...

Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already ...

You’ve heard of a sea cucumber, but how about a sea mushroom? This week, scientists described a mushroom-shaped sea creature that may be in a phylum all its own. Two species of the newly described ...

The group with the world's simplest animals -- tiny blob-like life forms with no organs and just a few cell types -- finally has a fleshed-out family tree. The study comes more than 100 years after ...

At present there are many animal phyla that contain only a few species. The existence of these small phyla can be used to test assumptions about speciation and extinction in multicellular animals. We ...

Jordi Paps receives funding from the University of Essex, the Royal Society, and the Wellcome Trust. Whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a ...

The group with the world’s simplest animals—tiny blob-like life forms with no organs and just a few cell types—finally has a fleshed-out family tree built by a research group led by the American ...
