That's an important part, yes. Morals are ideas, and as such evolve in an environment that makes them thrive, with the ones more adapted to the situation gaining more weight. If only because a population led by maladjusted ideas will disappear. Ideally, scientific facts thrive by surviving to experiments that fail to disprove them, but this does not exclude them entirely from that dynamic of social evolution. What experiments are performed is decided on the basis of what is desirable to investigate, according to the beliefs of the type of research that is deemed appropriate.
