It may have been a detrimental gene variant that although not terribly useful - it also didn't prevent the animal from surviving and reproducing.

Lots of animals including man have adaptations that aren't particularly help or the value of it is tied to some other benefit that doesn't show in the fossil record.

Its like vestigal legs in whales, doesn't help, doesn't hinder
