By studying these animals, we might be able to “learn some of their tricks” and use them to improve medical science on an astronomical level. Some 250 million years ago, the ancestors of dinosaurs, alligators and birds split from each other. To put it simply, all we need to do now is find a way to “encourage” these genes to act in the same way they do in lizards’ tails. As it turns out, this seemingly magical power is based (at least partly) in scientific truth. According to Margaret Wissman, DVM, avian and exotic veterinary consultant, reptiles such as green iguanas and bearded dragons will drop and regrow their tails, while others, such as crested geckos, can lose their tails but will not regrow them. After analyzing the genetic makeup of various lizards, researchers were able to isolate a group of 326 genes that “lit up” when tail regeneration took place. Maybe some of them did. Depending on the genus and species of lizards, their tails can either rapidly grow back after being dropped several times, or not grow back at all. Though, unlike other lizards, they are not known to regenerate their tails. Researchers are also suggesting this genetic breakthrough could lead to a treatment for arthritis. "Not just lizards: Alligators can regrow their tails too, new study reveals." Small reptiles can rapidly regrow their tails.
