10-20 years of trying to get groupers into freshwater water is a very short time period when talking about evolution. Evolution takes many years...
Also, with evolution, animals dont addapt. Living animals dont addapt to new changes. Their OFFSPRING do, Evolution is completely random. Those born with the random abilities to live better in the ever so new changing enviornment thrive, while the others die out. a single specimen wont just addapt.. its offspring are born with different abilities. If the enviornmental change is too derastic, the species will die out.
Its not a matter of a salterwater fish living in freshwater, its a matter of this species of fish changing from saltwater to freshwater.
evolution itself is constantly challenged, its a theory at best, not concrete itself.
