Why not?
Which part?
'You can't derive an ought from an is.'
Hume famously proposed this, and I agree with him in the main.
Just because it would be an evolutionarily successful strategy for men to procreate as frequently as possible with as many women as possible, does not mean that it would be moral to do so.
First of all, I don't think very many men actually believe that frequent indiscriminate procreation is the moral path to virtue. (Some few may believe that frequent indiscriminate intercourse is the path to fun, but that's quite different.) If we were moral slaves to evolution, this would not be the case.
But more importantly, just because it is a successful way to spread your genes and increase your genetic fitness, does not in itself mean that one ought to act that way.
Just because it is a fact that things fall down when you drop them, does not mean one ought to drop everything. To morality, the facts of evolution are just as irrelevant as the facts of gravity.
Now one could adopt or assume a meta-ethical axiom as the foundation for your moral system, like.
One ought to act in a way to increase one's reproductive success.
This is not an is statement. So it can't be derived from other is statements. But if you made this assumption then it would be moral (in this system) to procreate indiscriminately. But nobody but the most backward scientismist (or creationist strawman of an evilutionist) does such a thing.
Most people adopt some other moral system.
One ought to increase the well-being of everyone.
One ought to never impose on others what you would not choose for yourself.
One ought to behave in a way that it could become a general rule.
One ought to seek pleasure, in moderation.
