Every time evolutionary processes is mentioned, I get twinges.
A lot of people seem to fail to realize, that slow steady evolution is of course possible, but, most of the most significant changes in the course of life on this planet has happened as a result of massive global death in the realm of near total elimination.
Take for instance Toba erupting and it nearly wiped our species out. Most of the evolution up to that point was suddenly and violently altered. We are the decedents of a handful of survivors.
I am sure if Yellowstone were to erupt equally violently (as it has already done several times), it would sure set in motion a great deal of changes. There would be a great deal of us dealt out of the game and violently so.
Some days I wish it would blow too.
Changes to a species includes many different levels...not all of them are adaptations to natural disasters.
All domestic animals started out as wild, and over the 100,000 years +/- of man's era, we have modified all of them to fit various niches. Dogs, cats, horses, cows, chickens...all of them are the result of selective breeding (and exterminating the "unfit" ones)...so it is possible to "breed" a "new man", whether they are called Übermensch, Aryan, Jewish, Adamic, Superman, or even just Fred and Barney.
Perhaps "evolution" is too large a scale of a word, like "hurricane" is to "light breeze"...we may need a word that indicates a species change is manmade.
