Friendship is something that comes naturally to most human beings. If we are lucky, we may have multiple close friends, or even someone in our life that we call a “best friend”—a companion, a partner in crime. It is something that most tend to take for granted, and often the science behind friendship is neglected to be considered. According to a study done at the University of Pennsylvania, friends are often chosen by how reliable we believe they will be to us in our times of need, like allies in a time of war. This is not completely selfish of us, as with true friendships we do not expect anything in return. It is simply the solace of knowing that your ally will be there for you if an enemy attacks.
Another study done by the National Academy of Science states that it is more than just our superficial need for a support system that drives us toward one another. They suggest that many of our closest friends will some genetic resemblance to us. We may carry similar genes associated with sense of smell, taste, etc.
