					<description><![CDATA[Many years ago, a sudden event occurred that changed everything. Or at least, that is what we think now. But in truth, the event took longer than many today believe, and many of the specific details, the exact order of events, the actual meaning of each detail, are not fully understood.

					<description><![CDATA[One of the most interesting and exciting stories in science is that of the Younger Dryas. The Younger Dryas was a climate event that had important effects on human history, and that has been reasonably linked to some of our most important cultural changes, and ultimately some evolutionary changes as well.

Climate warming in the Holocene might have driven the extinction of this cold-adapted species, yet the species had survived previous warming periods, suggesting that &#8230; <a href="https://gregladen.com/blog/2008/04/07/did-sexist-white-males-cause-t/" class="more-link">Continue reading <span class="screen-reader-text">Did sexist white males cause the extinction of the woolly mammoth, or was it climate change?</span> <span class="meta-nav">&#8594;</span></a>]]></description>
