Moral law in Humans and other animals

[The Reality Salesman01]

Some people tend to think that we humans are special in that since we are "wired" to seek out that which is most advantageous to the survival of our species and that of our offspring, that on an "animal level" or an Atheistic level, there is no reason to explain why we are able to override those urges and act differently. Without being capable of recognizing some Divine Moral Law, how else can Atheists account for why we act one way when we are wired to act another? Why do we ignore our basic animalistic sense of eat or be eaten, and then behave in way that is in line with what we describe as "ought"?

If I brought a wild lion into my home, my family would be savagely torn to shreds in a short matter of time. There's not a single person that considers it murder if that were to happen because the Lion would simply be acting in a manner that is consistent with its nature. While it's true that dogs are capable of doing the same thing, I want to point out that one is inevitably going to occur while the other is quite scarce. Dogs are extremely common household pets while Lions are certainly not. My 135 lb beast of a dog is perfectly capable of shredding my family in a similar fashion and yet, I'm not in the least bit concerned of that being a likely event. My dog is an animal, just like me, and I too have an instinct that tells me that I ought not kill the members in the society in which I occupy. If killing out of instinct for survival is something that only humans are able to turn on and off, and this ability is a property given exclusively to humans in order to separate us from the "animals", then why is my dog so goddamned moral?
