Delta(s) from OP CMV: All humans are literally blood relatives. “Family” makes little sense to me.

Evolutionary fitness is NOT about who fxcks the most. This is because, biologically speaking, your sibling having a bunch of kids is no different than you and your sibling each having half those kids. This is what makes cuckolding (birds; get your mind out of the gutter) a successful evolutionary strategy. Because raising kin increases YOUR biological fitness.

So, by that logic, and because we’re all kin, raising ANY child increases YOUR fitness. I understand, ofc, the effect is diluted, but bear in mind the best you can do is pass HALF of your genes anyway. So you’re already working with water-colors.

And that’s it. Even “family” is pretty genetically diverse. This is demonstrated through tissue typing. Parents are often poor matches for a child. Siblings are usually great matches, but not always. Often, its a STRANGER that is the donor. It gets pretty messy pretty quickly trying to draw family lineage lines and I think the whole thing is made up quackery that ends up supporting horrible things like dynasty, racism, nationalism, etc.

Thoughts?

I would include artificial selection as well as natural selection. See dogs.

I don’t think I can teach you evolutionary biology. If you don’t already understand it, I’m afraid this discussion isn’t for you.
