Punxsutawney Phil crawled out of his hole in Pennsylvania today and saw his shadow, meaning we’re in for at least six more decades of people thinking a furry gray rodent that’s also known as a woodchuck can predict the weather.

Scientists at the University of Copenhagen have found that a single genetic mutation causes people to have blue eyes. They say that until about 10,000 years ago, everyone had brown eyes. One day a person was born with a mutated OCA2 gene and — voila! — blue eyes. That means everyone walking around today with blue eyes is descended from that person. So if you have blue eyes, the next time you see someone else with blue eyes, walk up, give them a hug and kiss, and say, “Hi Cuz!” But don’t get too friendly, it wouldn’t be a good idea to get too close to a distant relative. After all, inbreeding can cause genetic mutations. Possibly even something gross like — gasp! — brown eyes.
