Got great friends? It's in your genes!

The old saying goes that to have a friend you need to be a friend, but according to this new research, friendship may actually lie in the genes. By comparing the friendships of identical twins (who share identical genes) and fraternal twins (who don't), researchers found that genetic make up seems to play a part in choosing friends. Identical twins were much more likely to report choosing similar types of friends than fraternal twins. Between the ages of 8 and 11, genes seemed to influence friendships by about 30%, edging up to 50% as people near adulthood.

Is this information important? Probably not. I find, as an adult, I seek out people with whom I feel a connection; whether that's genetic or not doesn't make a difference to me. On the other hand, this study may add fuel to your teenager's fire when you argue over his or her choice of friends! What do you think?
