And evolution wouldn't have selected it unless it conferred some sort of advantage."The advantage of better-gripping fingers and feet would help our early ancestors as they foraged for food along lakeshores and by rivers, the researchers said."If it's in many, many primates then my guess is that the original function might have been locomotion through wet vegetation or wet trees," Smulders said."Whereas,[url=http://www.ksacinc.com/cheapgucci/?]gucci outlet online[/url], if it's just in humans that we see this then we might consider something much more specific, such as foraging in and along rivers and the like."</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Aeolus/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
