Morals" has a pretty shifty definition. There is a lot of behavior that various religions consider moral that I consider wrong, misguided, or flat-out evil. We do have experimental proof that most vertebrates, including rats, crows and humans, have empathy and a sense of fairness enough to engage in sharing behavior or to help out a stranger at cost to themselves.
A rat, for example, will pass up a food reward to free a trapped rat that's a stranger.
