Yes? I mean that happens all the time. Just because a trait isn't useful doesn't mean it will disappear. Sometimes it will stay even if it's harmful as long as it doesn't kill the individual before they reproduce.
- HeadsUpHigh 7y agoA harmful trait that appears in adolescence would disappear because it would kill you before reproductive age.
