Evolution does not and cannot give a shit about you is why really. Elimination by evolution requires it to be both utterly nonviable and not tied to anything else. Look at sickle cell anemia - one copy protects against malaria via mild blood cell deformation. Two makes them concave.
There are plenty of non-optimal things kept around because there isn't sufficient pressure to ensure it dies out.
- robotresearcher 6y ago> Elimination by evolution requires it to be both utterly nonviable and not tied to anything else. Neither of those things are required. Any disadvantage to reproduction frequency of an allele can lead to its extinction. Even a 'good' allele can lose to a 'better' one. (The scare quotes are to acknowledge that these terms are just frequency re-stated)

If they reproduce less often, they pass their genes less often. I think they say the trait is regressive.
