This Week’s Mtg on Cambrian Explosion (11/12/9)

I’ll just repeat the links I gave the first time we were going to give this topic, plus a new one I found the other day:

1.  Wiki/Cambrian explosion.

2.  Brief description from a U.K. university.

Also, I found this the other day: Scienceblogs.com.  It’s a group of about 40-50 blogs related to physical, life, other sciences.  Click on “choose a blog” and a list of some interesting sounding ones.  Two of the interesting-sounding ones to me are cognitive daily and  startswithabang.
