Can’t an inherited trait be “neutral”? By that I mean it confers neither a benefit nor a detriment? It’s my understanding that the baby toe, for example, isn’t particularly useful anymore. But having or not having the baby toe(s) isn’t likely to help or hinder a person’s ability to reach adulthood and reproduce. There must be a lot of traits like that, right? Like eye color or maybe wisdom teeth. No one (as far as I know) is selecting a sex partner based on whether their wisdom teeth were impacted or not.
