It turns out that if you look far enough back in time, you find that every single person with blue eyes who has ever lived in the history of ever is related to every single other person with blue eyes, however distantly, because of a single common ancestor from as far back as 10,000 years ago. Science is kind of awesome. So Tom Hiddleston and Michael Ealy (who are freaking beautiful*) are related to Franck Ribery and Alice Cooper (who are not) if you look far enough into it. Logistically, this means that half of Hollywood actors are related one to another.
Anyway, you can read all about it here.
*My deep love of Tom Hiddleston is well-documented. He’s pretty much the awesomest at life.
