Humans Choose Friends With Similar DNA 204
KentuckyFC writes "The study of social networks has long shown that people tend to pick friends who are similar to them — birds of a feather stick together (PDF). Now a study of the genomes of almost 2000 Americans has found that those who are friends also share remarkable genetic similarities. 'Pairs of friends are, on average, as genetically similar to one another as fourth cousins,' the study concludes. By contrast, strangers share few genetic similarities. The result seems to confirm a 30-year-old theory that a person's genes causes them to seek out circumstances that are compatible with their phenotype. If that's the case, then people with similar genes should end up in similar environments and so be more likely to become friends."

No kidding. I'm thinking that the majority of people live, breed and die within a few hundred miles of where they were born and this goes on generation after generation. One would expect a certain homogeneity in the range of genes within that population.

I find this study to be extremely flawed, not to say elitist / racist.
Yes, rednecks who listen to country music and drink cheap beer and whisky like to have friends who are also rednecks who listen to country music and drink cheap beer and whisky.
If the study had been conducted with 2000 subjects from culturally diverse places, like NY or Tokyo, I'm sure the results would've been a lot diferent.
I was going to post AC, but fuck it, I got karma to burn...

Yes, people who fit a stereotype of those I dislike like to have friends who are similar.
If the study had been conducted with 2000 subjects from places with people like me, I'm sure the results would've been more comforting to me.

I dont get how everyone on here keeps making the equation: genetics = race. Thats not what this is about.
I'm an engineer. Since I was a kid, I've loved to take things apart and put them back together. The closest friends I have in life are all from different parts of the world but they tend to be like me in that they also grew up taking things apart and putting them back together. So whatever gene-grouping is responsible for that behavior is probably shared by my friends from India, Russia and Sweden.

I would think that this would be much more interesting in a more egalitarian and pan-racial society.
