Does this work in the other direction? Do other animals have ethics?
There is a LOT being written (and that has been written) on animal ethics.
They may not be thought out ethical codes, but there are certainly rules of conduct towards one own species.
Konrad Lorenz's "On Aggression" is an early writer on this. His thesis is, basically, that the more weapons an animal has and hence the more its ability to kill a member of its own species, the more likely it is that there will be "rules" about use of said weapons.
Eg...if one wolf in a fight "surrenders" (adopts a specific posture) the victorious wolf is inhibited from killing it, while confined turtle doves kill each other with no apparent inhibition.
Of course, you can argue that this has developed via evolutionary pressure...but so have many of our ethics, I say.
I just tried googling for you...but every search term I can find lands at more and more re human ethical obligations towards animals.
I have some books of my own which I will try and hunt up.
