It may seem strange, but a recently-published study in the PLOS Genetics journal claims that whether your nose is long and narrow or short and wide, you may have your ancestors’ climate to thank.
Researchers from Ireland, Belgium and the U.S. used 3D facial imaging to collect nose measurements on nearly 500 participants of South Asian, East Asian, West African and Northern European descent. The researchers analyzed specific measures including nose height, nostril width, distance between nostrils, protrusion and total surface area of the nose and nostrils. Then, they compared these measurements with local temperatures and humidity in various geographical regions. The findings revealed that nostril width was strongly linked with climate. Wider nostrils were found in more hot and humid areas, and narrower noses were more common in cold and dry areas.
Personally, I’m blaming my nose on Uncle Albert. I seem to have inherited his nose.
