  1. Friends Display Genetic Similarities

    Friends share 0.1 percent more DNA with one another than with strangers, a controversial new study suggests. The statistically significant figure is drawn from research based on 2,000 people in the small community of Framingham, Mass. The study may indicate that people are more likely to befriend those genetically similar to themselves, although it’s unclear how we identify genetic similarity. Critics emphasize that in a small pool, ethnicity, population stratification and shared interests could also explain the similarity.
