Why We Love reveals the science behind all human bonds, not just romance. Evolutionary anthropologist Anna Machin explores how love - from parental to parasocial - shapes our health more than quitting smoking. Frans de Waal calls it "a lively guide" to our most complex emotion.

Have you ever wondered why heartbreak physically hurts? Why your chest aches when someone you love walks away? It turns out, love isn't just poetic metaphor-it's a sophisticated neurochemical system that hijacks your brain the same way cocaine does. We like to think of love as something mystical, beyond science's reach. But what if the poets got it backwards? What if love isn't a mystery at all, but rather evolution's most elegant solution to a uniquely human problem? Here's the evolutionary pickle we're in: humans are born ridiculously helpless. A newborn gazelle can run within hours. A human baby? Utterly useless for years. Our massive brains-the very thing that makes us special-created this vulnerability. Those big heads had to squeeze through narrow, upright-walking hips, forcing us to be born essentially premature. One parent alone couldn't possibly manage the burden of keeping such a dependent creature alive while also gathering food and staying safe. So evolution did something radical: it chemically bribed us into cooperation. That warm feeling when you hold your child, that euphoria when your partner walks through the door, that contentment sitting with your best friend-those aren't just nice feelings. They're biological rewards designed to keep you invested in relationships that literally determine whether you survive.
