A playboy would desperately give a great impression during the first date. The goal, in order to make womanhood terpincut charm. Is the greatness that is displayed is honest or false, that's later, an important short-term plan are fulfilled.
But do not be happy first, if you are a playboy, beware! The reason is, you probably will die early. Once the researchers said.
A new study led by University of New South Wales claimed that the men who pursue multiple women typically focused its growth stunted and died young. The reason, they can ignore the primary needs such as food.
These findings indicate that the association of men are not more common, though it has evolved because of the potential benefits that follow the natural limitations. Similarly, reports the Journal of Evolutionary Biology who quoted from the Times of India.
Head researcher Alex Jordan said, "Maybe this is nature's way of telling men to be more loyal to their sexual partners. We wondered why the world is not a place that is more chaotic."
"For men, especially those who have been married to a woman having to reproduce with great success, so you would think that such a rule should be better. In fact, our research shows that men pay a significant cost to the association that puts limits their number of sexual partners throughout their lifetime. "
For this study, researchers tested the behavior of tropical fish, as well as examine the cost of male reproductive lifetime. This is the first study involving vertebrate animals.
Males of many species increase their reproductive effort with foreign friends, so that became a phenomenon known as the Coolidge effect.
When male fish regularly supplied with new foreign female fish throughout their lives, they spend less time looking for food and more time pursuing females. Men who live with foreign women also grow more slowly and to those who have grown smaller in size, and tend to die faster.
Conversely, men who live with a spouse usually eat on a regular basis, continues to grow, and live longer.
"Great cost to individuals involved free association reveals the natural limitations on the chaotic behavior, undescribed in vertebrates. Perhaps those who want a more chaotic existence will see this as a warning," said Jordan.
"Conditions that tells us scientifically that extreme social evolution seems to be limited by the physiological cost involved, although the association has its own advantages, but may be too great for the long term," lid Jordan.
