People often talk about how their friends feel like family. Well, there's some new research out that suggests there's more to that than just a feeling. People appear to be more like their friends genetically than they are to strangers, the research found.
"The striking thing here is that friends are actually significantly more similar to one another than we were expecting," says James Fowler, a professor of political science and medical genetics at the University of California, San Diego, who conducted the study with Dr. Nicholas Christakis, a social scientist at Yale University.
