Why do we love people we're related to? Compared to strangers, why do we feel such a deep sense of connection with our family members? Sure, they're nice to us, we take care of each other, and we often live with them, but there has to be a deeper biological reason. That reason, unsurprisingly is evolution. In this video, I explain why taking care of our family, or even dying for them, makes sense in the eyes of evolution.
