A number of hypotheses propose that climate-driven environmental changes during the past 7 million years were responsible for hominin speciation, the morphological shift to bipedality, enlarged cranial capacity, behavioral adaptability, cultural innovations, and intercontinental immigration events. These hypotheses are based on correlations between global-scale climate shifts documented in oceanic deposits and events in hominin evolution recorded in continental fossil-bearing strata. <br> <br>For more information, please visit: <br><a href="http://scienceweek.com/2006/sw060217-4.htm " target="blank">scienceweek.com/2006/sw060217-4.htm </a> <br></font></td> </tr> </table> </td></tr> </table> <script type="text/javascript"></script> <script type="text/javascript" src="<http://pagead2.googlesyndication.com/pagead/show
