"it's NOT evolutionary until the behaviour turns up in succeeding generations." Well, even then it might not be evolutionary: in the event that the particular species concerned actively teaches its young, it might not indicate a change in the species, but may simply be that one member has learned and decided to teach. I'm thinking of the gorillas who know how to destroy snares - and teach subsequent generations how to destroy them. The species hasn't changed because they've learned to destroy snares - they're merely learning something new and valuable to the tribe. -D ------------------------- Dr. David T.
