I noticed an article on an interesting research on genetic similarities among friends, on Smithsonian.com (see HERE). It states that most friends “shared about one percent of their genome – about as related as fourth cousins. Most often, friends shared genes related to sense of smell, the authors found.” Wow, so friends really are family!! It’s a pretty interesting concept. I wonder how we would instinctively know, if these facts and figures are correct that is. Have you ever tried researching any of your friends’ genealogies? This could be a fun side project!
