Scientists find genes inherited from our prehistoric cousins increase tendency to rise early – useful in regions with short winter days
People who are early to bed and early to rise may have their ancient ancestors to thank for the habit – or at least the Neanderthals with whom their forebears procreated, scientists say.
DNA inherited from our thick-browed cousins may contribute to the tendency of some people to be larks, researchers found, making them more comfortable at getting up and going to bed earlier than others.
