Dimensio: Yes. No scientific theory can define morality
Your answer is correct, scientific theories are amoral. However, the question is ambiguous - it can be interpreted as asking if morality evolved.
IMO, the answer to that is an unambiguous yes. Cooperation and respect for others and their property have obvious, very strong survival value for the group. Any genetic trait that makes morality easier will be selected for. One of these traits is the ability to imagine what someone else is thinking or feeling, and to imagine oneself in the pother person's shoes. IOW, empathy.
All societies, from hunter-gatherer bands to modern cities, have strongly disapproved of murder and theft (at least within the group) and rape of another's wife. This is independent of their religious beliefs and the source of their laws.
