Thanx a lot for your follow-up. I think you are right that evolution
hasn't stopped, even if I do contradict my former attitude. I guess it is
evident that maybe Man is the only cause of the evolutionary processes now?
What I mean is, I feel that evolution that occurs now (such as the tuna
size) are through a result of artificial selection due to human influence.
Another example may be isolation of species after the construction of
highways, rather than the drifting apart of islands. Maybe this human
influenced evolution is a much faster process and so results in only
elementary changes like colour or size, rather than more radicle morphological
adaptations that have arisen over the millions of years. (?)
