This is a partial answer to your question.
According to "Only Humans Have Morality, Not Animals", (Guldberg, 2011), claims that morality is something unique to humans. Basically the author concludes with:
Human beings are not perfect and never will be, but we are special and unique among the animal kingdom. We are capable of making judgements about our own and other people's behaviour, and have the capacity consciously to change the way we behave and society as whole.
A key argument made in the article is that there is a great difference between instinctual connections and actions and human empathy and morality.
Further, according to the article "Is Morality Innate?" (Prinz), proposes that:
Morality is a byproduct—accidental or invented—of faculties that evolved for other
and proposes a somewhat negative, yet true conclusion:
Nonhuman animals are often
violent, but their potential for bad behavior may be lower than ours. Because we can
reason, there is a great risk that human beings will recognize countless opportunities to
take advantage of our fellows.
Essentially, it seems that perhaps morality is unique to humans owing to our abilities to reflect, reason as well as react.
