"But that's simply not true."Sturgeon have been around more than 100 million years and today consist of 29 species worldwide, including the lake sturgeon found in the Great Lakes.While there are fewer sturgeon species as compared to other fish they show a great variety in body size, suggesting rapid evolution in at least that one characteristic, the researchers said"Our study shows that sturgeon are evolving very quickly in some ways,[url=http://www.christianelouboutinoutlet.com]Cheap Christian Louboutin Shoes[/url]," Rabosky said. "They have evolved a huge range of body sizes. There are dwarf sturgeon the size of a bass and several other species that are nearly as big as a Volkswagen."</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>
