I don't think it is obvious at all. It could all be down to instintive behaviour, put there by God as a survival strategy.
Humans and animals differ in as much that human being posses a part of them that survives death, the part we call the soul. Animals may well have a part of them that survives after death, but God has chosen not revealed it to us.
Humans and animals may well share certain characteristics and abilities but one ability animals do not posses is to be able to distinguish between right and wrong. They have no moral awareness as we humans have. Animals may well indulge in what appear to us to be human behavior, but I would say they are just following their instincts.

Would disagree that it is just instinct Saundy. A new topic has been started
here discussing this.

How do you know that they cannot distinguish between right and wrong or that they have no moral awareness?
