Leonardo Da Vinci's DNA may be in his art, experts say

Scientists have wanted to study Leonardo da Vinci to see if his genetics hold the key to his genius for years. But there's a catch: Over 500 years since he died, his DNA has been impossible to find. He had no children, his grave was destroyed during the French Revolution, and while his bones were rumors to have been reburied, that's never been verified. Now scientists think the key may be in his art itself.
