    I’m surprised that mammals evolved to not regrow teeth. You’d think it would be a significant advantage.

      I wouldn’t imagine it’d play a role in reproducing though. It may help ones ability to live longer, but they have probably procreated long before tooth loss has become a major issue of well being or mortality.
