Seems to me that bacteria are the ones at the top of the evolutionary pyramid. They're the survivors!

What a coincidence. I listened to this on Ira Flatow's Science Friday. Fascinating!

I heard about this on NPR today when I was driving. Very interesting. Good clip.

Apropos our shared life with bacteria, here is a beautiful TED talk on the subject (I think I clipped it once).

Fast T friend-Thanks for the link. Excellent video. "Bonnie Bassler" also seems quite interesting. I enjoy yhe way she talks with her hands and her body language to emphasize her subject of discussion. What a GREAT TEACHER!
