Vestigial structures are remnants of features that were once functional in an organism's ancestors but are no longer needed in the current environment. Natural selection does not actively remove these structures because they do not typically have a negative impact on an organism's fitness. Since they do not hinder survival or reproduction, they are not actively selected against.
