Previous efforts to produce teeth in chickens had relied on introducing genetic information from mice, resulting in chickens growing mammalian molars. But a chicken's underlying ability to grow teeth derives from a common ancestor with alligators--archosaurs--that is more recent than the one linking birds and mammals.uring that time, the same two tissues from which teeth develop in mammals come together in the jaw of the mutant embryo--and this leads to nascent teeth, a structure birds have lacked for at least 70 million years. They don't make a molar, explains development biologist John Fallon, who oversaw Harris's work.
