"Just one or two changes across a huge body of data can make the difference between an animal being on one side of this bird-dinosaur divide or the other."</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>
