Society for Experimental Biology Why did animals with limbs win the race to invade land over those with fins? A new study comparing the forces acting on fins of mudskipper fish and on the forelimbs of tiger salamanders can now be used to analyze early fossils that spanned the water-to-land transition in tetrapod evolution, and further understand their capability to move on land. Research conducted by Sandy Kawano and Richard Blob at Clemson University compared terrestrial locomotion in...

New research from Duke University suggests a reversal in the order in which two four-limbed creatures transitioned from water to land.The Ichthyostega and Acanthostega, lived some 360-370 million years ago in modern-day Greenland.Scientists had previously considered Acanthostega to be the first vertebrate animal to possess limbs with digits rather than fish fins, but Viviane Callier, a Duke University graduate student, found fossilized evidence to suggest that Acanthostega may have had a...

LONDON (Reuters) - The first four-limbed animals on land may not have hopped or waddled but rather shuffled like modern-day caterpillars, according to new research published in the science journal Nature. Scientists from Uppsala University in Sweden and McGill University in Canada came to these conclusions after studying the fossils of the Ichthyostega -- a four-legged fish that lived around 360 million years ago. They noted that the construction of the creature's backbone ruled out wriggling...
