Big deal. Distant cousins. How distant? Does the author know their entire family tree, with all the distant branches? Everyone has 3rd, 4th, 5th and 6th cousins they've never heard of, let alone met. If the common ancestor is over 4 generations back it's no matter from a genetic standpoint. In California, it's legal for FIRST cousins to marry as long as they don't plan on offspring. The only creepy alert should be on the author.
There are often headlines which shouldn't be headlines, and usually I just ignore them. But this is just an idiotic excuse for journalism. First, report the entire story, you make it sound like their offspring should have extra toes when they may be cousins 200 time.....
