Nature programmed the neurobiological processes of early love to appear as something beyond the primitive sexual cravings of the genitals. So, from an evolutionary standpoint, it all leads to copulation and reproduction, but from the perspective of the individual who has recently fallen head over heels in love with someone, it is mostly about a sensation of warmth and delight, and rarely of sexual nature.

The lessons of relationship that our primordial ancestors learned are deeply encoded in the genetics of our neurobiological circuits of love. They are present from the moment we are born and activated at puberty by the cocktail of neurochemicals. It__ an elegant synchronized system. At first our brain weighs a potential partner, and if the person _s our ancestral wish list, we get a spike in the release of sex chemicals that makes us dizzy with a rush of unavoidable infatuation. It__ the _st step down the primeval path of pair-bonding.

Males of all species are made for wooing females, and females typically choose among their suitors. If you take a closer look, you can observe such behavior all around you. The beautiful bird chirping outside your window. It__ a mating call. That pretty little bird is trying to attract a potential mate, so that it can propagate its genes. Why does the peacock have such beautiful feathers? It is to attract a healthy female. He as well is trying to propagate his genes. Even we humans, are not much different from the rest of the animal kingdom when it comes to attracting potential mates. When women dress up for their night out at the club, they are doing so to look attractive. This is a subconscious evolutionary desire to attract as many potential mates as possible.... While women tend to grab attention with their looks, men on the other hand, tend to attract as many potential females as possible, by showing off their resources. When a man shows off with his fancy car, expensive gold watch and suit, or flexes his muscles and brags about how many credit cards he owns, he__ doing so to make himself desirable by healthy women, in order to propagate his genes. It is all in the pursuit of reproduction.

We live in an exciting time. We now know more than ever about our biology and about our history, allowing us to peer into the future with greater clarity than has previously been possible. But at the same time, the changes we are undergoing, brought about by our own advances in technology, medicine, transportation-- and by the growing impact we are having on the world around us-- mean that we live in a time in which the future looks increasingly less like the past. We have become an odd species, indeed, but our story is not yet over. Like all species, Homo sapiens continues to evolve, so there is one thing we can say with certainty: the people of tomorrow will not be the same as the people of today.
