Scientists are planning to hatch dinosaurs from chicken eggs by turning back the evolutionary clock to when birds were dinosaurs. They believe advances in DNA technology could make such a feat possible in 60 to 100 years.

Modern birds are the closest living relatives of dinosaurs like Tyrannosaurus rex, and some say that structurally birds are dinosaurs. Major differences between species can already be created or removed with surprising ease. Already one team at the University of Southern California in Los Angeles has succeeded in getting the beaks of chicken embryos to grow budding teeth. This is a feature bird ancestors lost 60 million years ago, soon after the death of the dinosaurs. Researchers have partially restored legs to snakes and eyes to eyeless cave fish. read more
