Science finds why men like big rear women......

Since Kim Kardashian's picture of "All About That Bass" songs, women's women are passing a glorious moment in the light.

The interests of the female format are not new, of course. Previous research has revealed that men's tastes have evolved towards women with thin, long wrists, signs of youth and fertility.

Now, a study adds a new nuance to the theory of evolution that stands behind the interest of men in bowels, or more precisely, for the curved backbones that create them.

"Women have to deal with the problem of relocating the center of the body during pregnancy," says one of the authors of the study, Eric Russell, a psychologist at the University of Texas at Arlington, for Huffington Post.

"Women who have the most arched backbone of the abdomen ... can redistribute the center of gravity of the body mass to reduce the relocation that occurs from pregnancy. Therefore, we hypothesize that men have a psychological adaptation that pleases these women as partners to pacify. "

In short, male preferences have evolved for this specific anatomical form because it makes women capable of withstanding some pregnancy without any harm and being in shape during pregnancy.

For the study in question, more than 300 men appreciated the attractive coefficient in feminine silhouettes that had a spinal curvature ranging from 26 to 61 degrees. Men seem to have a moderate bow, about 45.5 degrees, normal.

This bow would provide evolutionary advantages without displaying health problems such as back pain or sliding of spinal cord discs, according to researchers. They discovered that the key is exactly the structure of the spine, not just the fat and the muscles of the throat.

"Men can take their eyes off the hips and get information about the women's backbone without being aware of it," says Dr. David Lewis of the Bilkent University in Turkey and the lead study author for the Daily Mail. But it may be true that men also have the preference for the bow of the waist, and the size of the ribs.

The study was published on February 7 in the online Evolution and Human Behavior magazine. /@drt
