Early amphibians bit first, walked later

Even before they walked on land, early amphibians dined differently from their fishy ancestors and may have chomped on prey at or near the water's edge.Primordial amphibians such as Acanthostega, which lived 370 million years ago, were better at eating like a land beast than walking like one, according to Harvard University researchers.The study sheds light on a key evolutionary change during a crucial time in the history of life, as vertebrates were first leaving the water and colonising dry land.This transition set the stage for the appearance of the later major groups of land vertebrates like reptiles, birds and mammals.
