Your thoughts

I'm going to push your thinking from microbiological to a whole new area.  Can you take a look at Extinction event#Evolutionary importance of mass extinctions.  It makes a lot of references to extinction events and evolution.  I honestly have problems here, because extinction events are not a fundamental driver of evolution.  Speciation, ok, I can buy that.  I know you're busy and all, but maybe you can take a look and help reword it.  I haven't studied evolution in many many years, so maybe this section is accurate, although I don't believe it.  Thanks.
