Plasma-friendly conditions are found in space and where lightning strikes on earth. It's another possible origin of life.

They can, for instance, divide, or bifurcate, to form two copies of the
original structure. These new structures can also interact to induce
changes in their neighbours and they can even evolve into yet more
structures as less stable ones break down, leaving behind only the
fittest structures in the plasma</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blog.wired.com/wiredscience/2007/08/space-dust-its-.html">
"These complex, self-organized plasma structures exhibit all the
necessary properties to qualify them as candidates for inorganic living
matter," says Tsytovich, "they are autonomous, they reproduce and they
evolve."</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/602F6126-5B4B-43F7-AF4F-D7370D12EFB7/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>
