Palaeontology: Between water and land
Robert L. Carroll1
Abstract
The most informative examples of large-scale evolution are provided by major transitions between environments. Fresh research on an ancient amphibian shows how it adapted to locomotion both in water and on land.
One of the defining events in the history of life was the emergence of terrestrial vertebrates from early fish. The oldest known fossils that illustrate the transition to land are those of Ichthyostega from the Upper Devonian of East Greenland.
