I'm surprised you guys haven't discussed genetic mutation yet.
epigenetics involves genetic mutations...that is one of many reasons why it is so interesting to me...as more scientist get on board it will make for some interesting reading amongst other things...possibly breeding better animals and finding cures to diseases...
one of the most famous mutations I read about was when the flu virus that infected birds (avian flu)to be more specific geese and ducks...and the swine flu mutated...back in 1918 or so, neither of these would cause illness in humans...but over many years when feeding the hogs the geese and ducks would feed together and over many years of the avian flu and swine flu co-existing that one day they finally mutated and the new strain was able to infect many people...millions died all over the world with this new strain of flu virus...I am going way back before the internet on this one...
