Climate changed the shape of our nose

Why is everyone’s nose a different shape? A recent study says that the Earth’s climate could change the shape of our nose, in fact people with wider noses live in humid areas,  while people with narrower noses live in colder places, and so our nose is like a temperature controller. The scientists have obtained this answer analyzing the noses of Africans, Asians and Europeans and the research could help people with the heat or cold, and the humidity if they go to other countries.
