By Seriously Science April 30, 6: Compared to the noses of most other primates, the human nose is quite large and easily broken.
Why have we evolved such a risky appendage? They found that only the nose manipulations made the faces more or less attractive, with centered nose tips being the most preferred. How this relates to fitness remains unclear, but you should probably get one of the devices shown to the left…you know, just in case.

The spectacular human nose: They are cost free and advantageous to high quality individuals, but disadvantageous to low quality individuals, as poor quality is easier perceived because of the amplifier.
For an amplifier to evolve, the average fitness benefit to the high quality individuals should be higher than the average cost for the low quality individuals. The human nose is, compared to the nose of most other primates, extraordinary large, fragile and easily broken—especially in male—male interactions.
May it have evolved as an amplifier among high quality individuals, allowing easy assessment of individual quality and influencing the perception of attractiveness? We tested the latter by manipulating the position of the nose tip or, as a control, the mouth in facial pictures and had the pictures rated for attractiveness.
Our results show that facial attractiveness failed to be influenced by mouth manipulations. Yet, facial attractiveness increased when the nose tip was artificially centered according to other facial features. Conversely, attractiveness decreased when the nose tip was displaced away from its central position.
However, whether such centering is related to individual quality remains unclear. A set of pictures used for attractiveness evaluation. One set of pictures, in which the right side of the nose and the mouth were used to make the trait symmetric A unmanipulated face B right symmetric, centered mouth C right symmetric mouth, skewed 0.
The presence of an attractive woman elevates testosterone and physical risk taking in young men. What makes a sexy leg sexy? Why poor, hungry men prefer bigger breasts. The bottom row of pictures looks cartoonish.
The last picture looks like an obvious photoshop. This is so stupid stupid shallow world. Very few humans realize they are sexually biased more attracted towards symmetric individuals.
People seek out equally symmetric people as their partners. So you take a bunch of people from the same cultural background where symmetry is associated with beautyand you show them pictures of more-or-less symmetrical faces. When they find the symmetrical pictures more beautiful, you make up some hardly testable hypothesis about how this has Does my nose look like a penis do with mate selection, and evolution and blah blah blah.
I chalk it up to our narcissstic attraction to ourself, which means we seek out those who look similar to us. We highlight the funniest, oddest, and just plain craziest research from the PubMed research database and beyond.
