These guys are barking up the wrong tree:
'Some researchers question whether dogs experience feelings like love and loyalty, or whether their winning ways are just a matter of instincts that evolved because being a hanger-on is an easier way to make a living than running down elk.'
I question whether these researchers really have 'questions' and 'findings,' or if they have just evolved to act as if they because being a hanger-on around grant-writing agencies is easier than working for a living.
'Raymond Coppinger, a professor emeritus of biology at Hampshire College, noted in his landmark 2001 book, “Dogs,” that “best friend” is not an “ecological definition.” And he suggested that “the domestic house dog may have evolved into a parasite.”'
You know what else is not an "ecological definition," Raymond? Professor emeritus. And I suggest that some intellectuals have evolved into parasites.
