Some geneticists did, and their discovery could spur work to help adults one day grow new teeth when their own wear out.A single gene appears to be in charge, preventing additional tooth formation in species destined for a limited set.When the scientists bred mice that lacked that gene, the rodents developed extra teeth next to their first molars – backups like sharks and other non-mammals grow, University of Rochester scientists reported Thursday.Read more ….
