Is there something else driving the variation seen in nose shapes across the world? As far back as the s, Arthur Thomson — a British anatomist and anthropologist — pointed out that long, thin noses tended to occur in colder, drier regions, whereas shorter, wider noses more often appeared in hotter, more humid areas. Although the rule is well-established, it was not clear whether the differences arose as a response to selection pressures, or whether it was simply due to genetic drift — chance mutations, conserved without any particular survival benefits.
Researchers set out to uncover whether nose size evolved as an adaptation to climate. Once the 3-D data had been analyzed, the team concluded that the width of the nostrils and the base of nose measurements across these regions could not be explained by chance alone.
They also found that wider nostrils correlated with populations whose ancestors evolved in warmer, more humid regions. This suggests that climate was a driving factor in the evolution of nose shape. The theory is that narrower nostrils alter airflow in such a way that the mucus-covered nasal membrane can warm and humidify incoming air more efficiently.
This would help individuals with narrower noses to survive better in colder climes and, therefore, be more likely to reproduce. Over time, this would have slowly driven nose size down. Of course, climate is not the only factor that has had a large impact on the evolution of the nose. For instance, cultural preferences for nose shape are thought to play a part. If a certain culture finds larger noses attractive, then individuals with genes that prescribe a larger nose are more likely to breed and spread their large nose genes to the next generation.
This finding is in line with the consensus that most human variation is shared among populations and primarily due to genetic drift. Traits like skin pigmentation and nostril width are exceptions rather than the rule. The current findings are fascinating in their own right, but they could also have implications for medicine.
Their noses are featured with enlarged nostrils, wide and rounded tips and a lack of protruded nasal bridge. West Africans have the widest noses widest nostrils , while north Africans tend to have the smallest wide noses. Moreover; the distance between the nasal alare are significantly larger in west Africans as compared to individuals with European ancestry.
The cartilage might require extra support. African or American? African Americans have wide noses with wide or low nasal bridges, flared nostrils and puffy tip. Hispanics also have wide noses but with a hump or a dropping tip, they also have thicker oily skin and a small hump. Native American noses tend to have depressed root. The sizes are different from one person to another but they have a bit of short base and they are wide. America also have people of mixed races like American-Mexican who have low roots, drooping tips and normal bridges.
Other people who are Native Americans-Europeans have wide tip and thick skin. The Mediterranean race includes people from southern Europe to central Asia. They tend to have noses with a hump in the region between the tip and forehead and a slightly drooping tip. No matter what lies behind this, Arab noses are believed to be similar to African. A rounded fleshy tip is their common trait. Located in the center and in front of your face, your nose is the most noticeable facial element.
Accordingly, plotting your nose shape would help you find out what type of nasal surgery would fit you. With the details of the nasal shape for any particular ethnic group, surgeons will be able to offer patients to reach the most desirable cosmetic results.
Septoplasty and rhinoplasty are the two dominant nasal surgeries which can be done to give you a healthy aesthetic nose. Septoplasty refers to the surgical correction of defects and deformities of the nasal septum space existed between the nostrils , while rhinoplasty is the correction of nose shape including reshaping and resizing the nose.
So, to enhance your nasal shape, rhinoplasty seems to do the trick for different types of nose shapes in different races. Depending on your nose and the results you want to get out of your surgery, you may be recommended to go for natural, dolly, or semi-dolly nose surgery.

Do some research on Native Americans. This section seems to refer to African Americans. African Americans for the most part do have noses that are similar to Africans, but African Americans are not fully African, there are great variances in the types of noses that they can have.
So if you can imagine there is a side range of nose types within this community. You have brocken up Europeans into different races but lump Africa into one race under the Black banner. You have said nothing about East Africans , Aboriginal , koisan etc. Yes, we do have some wide noses, but so do many South and Southeast Asians…anyhow.
Then how does talking about Africans automatically warrant comparison to Europeans when this isnt done with any other group…? I think the Mediterranean race is bogus. Most Western Eurasians belong to the same broad racial group and nose shapes over lap.
The girl in the picture likely had plastic surgery. Also there are different types of Africans, not all have the same nose. A lot of people tell me that my nose is typical. Anybody can have any nose shape. So , why are people saying one type of nose belongs to this race or that race? You already have a category for Europeans and Africans, they are not American at all. Therefore, the technique here becomes radically different.
Just because a surgeon knows how to do a Caucasian nose, he may not necessarily know how to do an Asian nose. Only a select few plastic surgeons operate on Asian noses for this reason. When performing rhinoplasty on the Asian patient, the goal is not to reshape the nose to look completely Caucasian, but to reshape the Asian nose to fit in with surrounding facial features in a way that promotes harmony and balance.
Caucasian men and women, much of the time, seek to have the nose reduced, whereas the Asian patient often needs the nose to be built up in order to become more prominent on the face. In his more than eighteen years of experience performing rhinoplasties, Dr. Kwan has seen successful techniques, as well as those which miss the mark. The key is to treat the Asian nose differently than a Caucasian nose in order to avoid:.
The various characteristics of the Asian face are beautiful, and should remain so even after enhancement with an Asian nose job in our New York City facility.
