Everyone goes on about the human/cat and human/dog relationship.
What about the human/chicken relationship?
Simply, put those bastard bustards are delicious. They’re tamable, foolish, and delicious. But if you as a paleolithic human have the patience to not simply eat every one you catch, they will make you endless protein in the form of eggs and more chickens.
I expect this was a major development in human awareness. When we attained the sense-knowledge that compassion and care lead to better outcomes than surrendering to base appetites.
I know from personal experience: you can cuddle chickens.
Perhaps we underestimate one of our most valuable animal companions.
After all, there is a certain humility to be found in the act of making friends with something you will eventually eat.
