Men's noses are on average 10% more than women Bashny.Net

Because men need more oxygen for their myshts



Just imagine - in the world lives more than 7 billion people, and each of them has its own unique and unmistakable nose. Researchers from the United States found that the size of the nose is determined not only inherited genes, but also, for example, sex man - most men noses more than women.

Dr. Nathan Holton from Iowa State University and his colleagues studied the noses of 20 female and 18 male Caucasians. Scientists came to the conclusion that the size depends on the noses of human muscle, because the large amount of muscle requires more effective supply of oxygen, and this big noses do better.

From birth to about 11 years old noses boys and girls do not differ, but with the onset of puberty and, as a result, a set of muscle mass, men's noses are growing more intensively than women. On average, the difference in the amount of up to 10%.

Even if men and women are almost identical in weight and stature, his nose almost always greater than the first because of the structural features of the body: in the male body muscle percentage higher than in women.

Nathan Holton points out that during the evolution of the human nose has also changed in size: from Neanderthal noses were larger than the modern representatives of the species homo sapiens, the reason for that - all the same need for oxygen. Our ancestors because it has been developed muscles are much higher, and with a decrease in the volume of muscle nose becomes more compact.

Scientist believe that the size of the nose depends not only on gender, but also on ethnicity or race. To confirm this hypothesis, Holton and his colleagues continue to study the noses of different countries and continents.
