An obscure creature called Acanthostega was responsible for a momentous step in the evolution of life on Earth. Essentially a fish, it was nonetheless the first animal to emerge from the water and ...

The first 3-D reconstruction of the skull of a 360-million-year-old near-ancestor of land vertebrates has been created. The 3-D skull, which differs from earlier 2-D reconstructions, suggests such ...

Almost half a billion years ago, dry land was dominated by plants—at least until tetrapods (four-legged animals) crawled out of the water and onto the shore in one of life’s most vital evolutionary ...

It's a classic chicken-and-egg conundrum: Did the distant ancestors of land animals come ashore and then evolve legs, or did they evolve legs and then come ashore? This is a daunting question ...

DURHAM, N.C. -- New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to ...

Ancient aquatic amphibians developed the ability to feed on land before completing the transition to terrestrial life, researchers from Harvard University report this week in the Proceedings of the ...

A study of the jaws of one of the earliest known limbed vertebrates shows the species still fed underwater, not on land. Scientists from the University of Lincoln, University of Zurich, University of ...

Researchers have shown that fossils of the 360 million-year-old tetrapod Acanthostega, one of the iconic transitional forms between fishes and land animals, are not adults but all juveniles. This ...

The first 3D reconstruction of the skull of a 360 million-year-old near-ancestor of land vertebrates has been created by scientists from the Universities of Bristol and Cambridge. The 3D skull, which ...
