This is an absolute eye-opener for me, a sort of mental game changer; because I was under the impression that these near-human behaviours were to be found in a small subset of the non-human life forms including the ape family, elephants, dogs and dolphins.
I have never studied the subject in any depth; but over the years I got the impression that this special levl of intelligence was to be found just in those particular classes. So I am going to go back to Square One now to ponder the implications of this information.
Thanks again!
