Study: Friends share similarities in their DNA
NEW YORK (AP) — You may be more similar to your friends than you think: A study suggests that the DNA code tends to be more alike between friends than between strangers.
That's beyond the effect of shared ethnicity, researchers say. And it could be important for theories about human evolution, says James Fowler of the University of California, San Diego.
He and Yale researcher Nicholas Christakis present their results in a paper released Monday by the Proceedings of the National Academy of Sciences.
How much more alike are friends than strangers? Not much. Imagine the small similarity between fourth cousins, people who share a set of great-great-great grandparents.
The study included 1,932 participants in a long-running health study in Framingham, Massachusetts. Researchers knew who was close friends with whom from the 1970s to the early 2000s because of information gathered for the study.
