Seems many factors change the DNA very quickly as opposed to thousands of years :
eg) red foxes caught from the wild within a couple of generations change colours and become docile
b) humans who snorkel with suntan lotion has some DNA effect on the corals nearby ( the corals have some DNA changes that would be detrimental to it )
c) the folks at AMI in austraila are trying to breed super corals that would be more resistant to the climatic changes going on in hopes of saving the natural brood stock out there... this can happen in relatively a short span of an years as opposed to the thousands of years of natural incremental changes
and the root of it is of course mankind. I am sure the feed the hatcheries get has weird medicines and steroids of some sort to keep the fish from getting sick and grow faster.
