Well, I don’t know about all this. I have to ask myself why some animals exhibit what sure looks an awful lot like loyalty and even affection bordering on love for their masters. Every once in a while I read a story about a dog (seems it is always a dog but maybe other animals too) saving the life of a human master - sometimes incurring injury or even death in doing so. How do the scientists explain that kind of behavior? It certainly makes no sense in terms of “instinct”.
But then I guess I shouldn’t be surprised. Scientists have so far utterly failed to explain honor, love, loyalty, faith, honesty or any of the higher ideals that humans express routinely. And scientists, so far as I am aware, are all humans. You would think that what with working with a human mind every day of their lives they would have developed some insight as to how and why it works the way it does. But they haven’t. Why should it be expected that they will do any better with the minds of non-human creatures?
Magpies remember when they leave a twig on my deck and will return to retrieve it. Even tho they have other bad habits, Magpies will not remove a twig belonging to another bird.
Obviously, you haven’t read The Moral Animal by Robert Wright.
You might find it thought provoking.
