It's a social construct created by Humans, whether you claim it was created by Religion or not. I do not think there was any divinity in it's origin, as other animals have been seen to behave morally, whereas Religions typically claim that their God only gave morals to humans.
(And i find it insulting to Humans as a species to claim that we could only come up with rules and morals by dint of Divine Intervention, but that's a whole other can of worms.)
Like Your Creepy Stalker said, morality is not unique to humans.
Besides that, we humans "created" our morality by ourselves. Religion and everything it contains is man-made too, don't forget that.
The focus is in the animals part. I find claiming that some animals have a morality too, like it seems by your words, is just somewhat of a "passing the boiling potato to the hands of others" rather than an answer. If humans and animals share this thing is not the issue, in my opinion, since it doesn't solve at all the problem of the source of the morality.
Said that, I'm now getting curious about the way you can prove that animals have a morality. I heard some people speaking about it before, but they felt to me like speculating on the bandwagoning ideas of veganism, specism and the others that are on trend thesedays.
I'm an animal lover and have a dog, and yes, sometimes I think it has somewhat of a "morality". But eventually realize that those feelings are no more than an impression of mine flowing from emotions. But I hope science denies me
the root of morality, right or wrong is a person perspective or popular agreements on certain topics. the mayan are great example.
they viewed blood as a potent source of nourishment for the maya deities, and the sacrifice of a living creature was a powerful blood offering. people blindly agreed to follow because it was taught as the "Right" thing to do.their refusal of offering would be considered an act of defiance. the "Wrong" thing to do.
in India it's considered wrong to eat cows, were as in the west it's a Sunday cookout. in the 1900s it was fashionable to wear fur. were as today it's frowned upon.
it's pretty much majority rules. 1000 years from now the word right and wrong will hold different values.
You indeed get a point proving that moral laws aren't equal and are subjected to changing between society and society. But if you think about it, even Mayan and the most cruel civilities that come to your mind share some common "fundamental" points. For example, stealing and killing, yet under certain measures, are condemned by every society we know.
