See this is a strawman. Science doesn't suggest anything that we ought do. Science isn't in the business of building morality. We do this on an individual level. In fact we sometimes impose our sense of morality onto others.

What do you think we ought to do? Let the weak perish? Fight for territory and mating partners? There is an ethical dimension to many aspects of biological science.
What I personally think is one thing, what the collective human moral acceptance thinks is another. How you personally feel about it is also another.
Do I think we should keep those humans who are not healthy or providing to the human progress? I don't know. If I don't have to be personally responsible for them then it doesn't bother me.
Should we have to struggle for mating partners. Hell yes we should. I think people are not picky enough and make horrible decisions and choices in partners. This is just my opinion though, I shouldn't be able to dictate to others who they decide to copulate with. I don't think anyone else should have that right either. But fight, sure.

Is promoting evolution a good adaptation for the species from an evolutionary point of view?
Yes. Evolution is a fact. It is reality. It is a great basis for many medical and biological businesses. Understanding it is important to understanding humanity and life in general. Weather you accept it to be reality is your own choice but why anyone would actually reject something that is true just shows their ignorance.
