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
