Other than that it was a facinating article.

This reminds me of a radio show we recorded last week, about NASA's plan to search for <a href="http://www.earthsky.org/clear-voices/51756/steven-benner" rel="nofollow">"weird life"</a> on other planets. In other words, life on other planets might not look like anything we currently imagine. Granted, we imagine bacteria. But 600,000-year-old bacteria? I love it when we find out we don't know everything ... or even nearly everything. Deborah Dan, interesting discovery!
