Why did southeast Asians evolved with flat nose?
The flat nose is a common facial feature among Southeast Asians. This physical trait is thought to have evolved as an adaptation to the region's hot and humid climate. A flat nose helps to cool the air as it passes through the nasal cavity, providing relief from the heat. Additionally, a flat nose may have provided an advantage in hunting and gathering, as it allowed individuals to breathe more easily while running or swimming.
Flat noses are not unique to Southeast Asians. They are also found in other parts of the world, such as Africa and Australia. In these regions, flat noses may have evolved for similar reasons, such as adaptation to heat or hunting and gathering.
While the flat nose is a common facial feature among Southeast Asians, there is still variation in the shape and size of noses within the region. This variation is likely due to a combination of genetic and environmental factors.
