Genetic drift, which was mentioned previously. We have a very narrow view of human evolution because we’ve been around as sapiens for X amount of time, but we evolved from ancestors that survived because of some of those traits. Now some of those things aren’t as relevant, but because they don’t hurt our survival (and few things do with modern medicine) they happen to still be present in the majority of people.
One of the symptoms of not appreciating our entire evolutionary journey is not realizing we aren’t fully evolved and that there’s no end goal of evolution- it’s not heading in a specific direction, but more like all directions all at once because of variation. The directions that just survive long enough to reproduce have ‘suitable’ genes, which is how things become more prevalent without being ‘necessary for survival’.
