Thanks to Janine for sending in this story about a VERY polydactyl cat. Last month I wrote about the evolution of five fingers and toes and the constraints on this arrangement. Though loss of digits is not an uncommon evolutionary change, gaining digits is very rare. It is a phenomenon seen in polydacyl cats; however, I don't think anyone understands why cats are able to increase the number of their digits without 'repercussions' to the rest of their patterning. Anyway, click here to read about the polydactyl cat who has 26 fingers and toes!
