A serious project to revive dead Beatles songwriter John Lennon is underway.The project stems from a tooth that Lennon left to his housekeeping in the 1960s. Decades later, the tooth has appeared at auction several times for prices as high as $30,000, and its current owner is leading the way for a project to bring the rock icon back to life."If scientists think they can clone mammoths, then John Lennon could be next," said the current owner, dentist Michael Zuk.Zuk enthusiastically tours the tooth around the world and has released a photo book of "rot star" art (seriously) on it, according to Ultimate Classic Rock. Now he's made the new DNA project his life ambition."To potentially say I had a small part in bringing back one of rock's greatest stars would be mind-blowing," added Zuk. "I am nervous and excited at the possibility that we will be able to fully sequence John Lennon's DNA, very soon I hope. With researchers working on ways to clone mammoths, the same technology certainly could make human cloning a reality."If the project proves possible, do you think it would be moral or fair to bring the singer back to life? Could the clone ever be as talented as the original Lennon? Let us know below.
