Are you a morning person or a night owl? A new study shows people who thrive later in the day may be smarter than early risers.

Researchers claim it's the result of an evolutionary advancement which marks out more intelligent individuals, while those with lower IQs tend to restrict their activities primarily to daytime.

So can you train yourself to stay up later? Not likely.

Studies have shown your sleep preference is mostly genetic.
