Your closest friends often share similar DNA with you, just like distant relatives, according to research from Yale University and UC San Diego. A study published in Proceedings of the National Academy of Sciences (PNAS) found that close friends are genetically more alike than strangers—on average, sharing about 1% of their DNA, which is comparable to the genetic similarity between fourth cousins. Researchers Nicholas Christakis and James Fowler suggest that people may subconsciously form friendships with those who are biologically similar, influencing everything from shared interests to health patterns.
