How We Feel Love And Why We Love ?

It is widely believed by evolutionists that monogamy suppresses reproductive behavior. However, scientists acknowledge that reproductive behavior is not fully understood yet, and especially when it comes to romance which seems to play an important role in it.

” We have only a very little understanding of what romance is in a scientific sense ” — John Bancroft, M.D. director emeritus, Kinsley Institute

pair boding - loveAt a glance our mating rituals seem to serve two clashing purposes: on the one hand, we are driven to mate a lot; on the other hand, we appear to be hardwired to seek an emotional bond which interferes the former. Studies of the brain with functional magnetic resonance imagers (fMRIs) show what even three regions of human brain are contributing in love processing which turns it into a powerful feeling. The earliest fMRIs of brains in love, taken in 2000, revealed that the sensation of romance/love is down to dopamine which creates craving, motivation, goal-oriented behavior and ecstasy. Anthropologist Helen Fisher with the colleagues conducted fMRI scans of people who are newly in love and have found that their brain areas are working particularly hard in distributing dopamine. Thrill signals start via not just dopamine but also serotonin, which is popularly thought to be a contributor to feelings of well-being and happiness, and, importantly, vasopressin and oxytocin (OT) . The latter substance proves to have a direct impact on emotional bonding. When oxytocin in monogamous prairie voles was increased by scientists, they cuddled more and mated less. When it was blocked, they mated but didn’t cuddle. If anything that suggests that nature put quite an emphasis on emotional bonding and if so there must be a significant value to it.

Indeed recently new scientific evidence have emerged which challenges prevailing believe that sexual monogamy is limitation to reproduction. Conducting a research since 1996, anthropologist Eduardo Fernandez-Duque and colleagues published a paper in 2008 giving an insight into reproductive behavior of monogamous Owl monkeys. According to Fernandez-Duque under certain circumstances Owl monkeys were forced to change their partners, however if they managed to stay with the same partner they produced 25 percent more infants than if they had to change . The study results made anthropologists to agree that pairs-bonds must have played an important role in the origin of human societies.
