The claim is that moral intuitions exist because they were selected for, and they must have been selected for because they increased reproductive fitness.
But morality isn’t just moral intuitions. It includes “eat fish on friday”
Similarly, we should expect moral behavior to the degree that morality is more rewarding than immorality.
That doens’t follow. Fitness-enahncing and gene-spreading behaviour don;t have to reward the organism concerned. What’t the reward for self sacrifice?
The picture is muddied by there being both genetic and memetic evolution,

Sure. We should expect such rules to be followed to the degree that they are prudent.
What’t the reward for self sacrifice?
There are several; kin selection, reciprocal altruism, and so on. In some cases, self-sacrifice is the result of a parasitic relationship. (Kin selection appears to have a memetic analog as well, but I’m not familiar with work that develops that concept rigorously, and distinguishes it from normal alliance behaviors; it might just be a subset of that.)
Sure. We should expect such rules to be followed to the degree that they are prudent.
Again, I have no idea what you mean. Morality does not predict self-centered prudence, since it enjoins self-sacrifice, and evolution doenst predict self-centered prudence in all cases. It is not selfishly prudent
for bees to to defend their colony, or for male praying mantises to mate.

If you pass on the idea that self-sacrifice is virtuous, in a persuasive sort of way (such as by believing it yourself), you’re marginally more likely to enjoy the benefits of having someone willing to sacrifice their own interests nearby when you particularly need such a person. Of course, sometimes that meme kills you. Some people are born with sickle-cell anemia and never get the opportunity to benefit from malaria resistance; evolution doesn’t play nice.

that’s a considerable understatement.
