"We also found evidence of a new, more simple path by which skeletal structures would have evolved.""The transition from ocean-dwelling to land-dwelling animals was a major event in the evolution of terrestrial animals, including humans, and an altered hip was an essential enabling step."Our research shows that what initially appeared to be a large change in morphology could be done with relatively few developmental steps," she said.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
