A guy gave chickens back their tails so they would walk like dinosaurs again

Modern birds, including chickens, are the only living dinosaurs. Their ancestors possessed a long, bony tail that shortened drastically and nearly disappeared over the course of evolution. Inventor Allen Pan decided to remedy this by creating a special cyber-tail for a chicken. Thanks to the device, the bird immediately began holding its body more upright—compensating for the shifted center of gravity—and moving almost like a dinosaur; remarkably, it didn't even seem to notice the tail's presence.
