I've got good news for all romantics

You know the saying "survival of the fittest"? It's usually used when describing aggression or some other negative human behavior. But the latest news from scientific journals is that human evolution may depend on three very surprising characteristics: monogamy, nurturing, and romance.
First - monogamy. Scientists at Kent State University say that our ancestors might have become monogamous earlier than we thought. Based on fossil skulls, they now believe that males and females were roughly the same size, which points to monogamy. When the male is much larger than the female, it indicates a harem-type of setup, like that of the gorilla. Since monogamous males spend less time fighting off other males, they don't need to be as big.
Nurturing. Ronald Lee, a professor of demography at the University of California, Berkeley, says those who care for their kids live longer. He believes that reproducing and populating isn't just about bearing offspring. It's about investing in them, too. Lee's research shows that species that spend the most time nurturing their young have the longest life spans.
And finally, "survival of the fittest" might have depended on romance. You wouldn't think a caveman would bring flowers to his cavewoman. But according to a study published in the journal Evolutionary Psychology, there's an evolutionary benefit to being a Don Juan. Research shows that as humans developed, the females chose the guys who were most willing to provide food and care for their children after they were born. The first gifts were more likely to be fresh killed meat than freshly picked flowers, but the idea was the same. Now you know!
