The title of the clip itself is tempting: "Oh, well... What if... I mean how would it be... Okay, forget it."

Earwigs. Double penises. Who could ask for anything more?</p> <P>A Canadian researcher couldn't. In the journal Nature, he writes about how evolution may have conspired to rob some animals of their second penis -- and give precedence to the one on the right. </p> <P>The full study isn't available online (unless you pay), but Slate got a hold of it and has this summary:</P><BLOCKQUOTE><P>Differences among earwig species suggest males originally had two
penises, but as they increasingly favored the right one, "the
less-preferred (left) penis disappeared altogether." High-minded
conclusion: Behavioral changes can drive evolution, not just the other
way around. Translation: Use it or lose it.</P></BLOCKQUOTE><P>And in case you were wondering, "many spiders, dragonflies, shrimp, lizards and snakes have two penises."</p> <P><A href="http://www.nature.com/nature/journal/v444/n7120/abs/444689a.html">Caught right-handed</A> [Nature]</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/3AE74B89-F2BD-4A17-892B-E73313C3135D/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
