Early risers may have inherited their habits from Neanderthal ancestors, according to a new study published in the journal Genome Biology and Evolution. Researchers analyzed archaic DNA from Neanderthals and the closely related Denisovans, and compared their findings to modern DNA in a medical database. Researchers found that people who described themselves as early risers were more likely to show traces of Neanderthal DNA in their genetic codes.
