summary - After humans and Neanderthals met many thousands of years ago, the two species began interbreeding. Recent studies have shown that some of those Neanderthal genes have contributed to human immunity and modern diseases. Now researchers have found that our Neanderthal inheritance has contributed to other characteristics, too, including skin tone, hair color, sleep patterns, mood, and even a person's smoking status.
