O.K., let’s cut out all this nonsense about romantic love. Let’s bring some scientific precision to the party. Let’s put love under a microscope. When rigorous people with Ph.D.s after their names do that, what they see is not some silly, senseless thing. No, their probe reveals that love rests firmly on the foundations of evolution, biology and chemistry. What seems on the surface to be irrational, intoxicated behavior is in fact part of nature’s master strategy — a vital force that has helped humans survive, thrive and multiply through thousands of years. Says Michael Mills, a psychology professor at Loyola Marymount University in Los Angeles: “Love is our ancestors whispering in our ears.” It was on the plains of Africa about 4 million years ago, in the early days of the human species, that the notion of romantic love probably first began to blossom — or at least that the first cascades of neurochemicals began flowing from the brain to the bloodstream to produce goofy grins and sweaty palms as men and women gazed deeply into each other’s eyes. When mankind graduated from scuttling around on all fours to walking on two legs, this change made the whole person visible to fellow human beings for the first time. Sexual organs were in full display, as were other characteristics, from the color of eyes to the span of shoulders. As never before, each individual had a unique allure. When the sparks flew, new ways of making love enabled sex to become a romantic encounter, not just a reproductive act. Although mounting mates from the rear was, and still is, the method favored among most animals, humans began to enjoy face-to-face couplings; both looks and personal attraction became a much greater part of the equation. | Romance served the evolutionary purpose of pulling males and females into long-term partnership, which was essential to child rearing. On open grasslands, one parent would have a hard — and dangerous — time handling a child while foraging for food. “If a woman was carrying the equivalent of a 20-lb. bowling ball in one arm and a pile of sticks in the other, it was ecologically critical to pair up with a mate to rear the young,” explains anthropologist Helen Fisher, author of Anatomy of Love. While Western culture holds fast to the idea that true love flames forever
