You probably believed that every part of your body is genetically inherited. Apparently, your nose shape is “designed” by climate, not by your parents. The nose shape is important for helping you condition the air you breathe. This might be the reason why it was made by climate and not genetically inherited.
A new study shows that the nose shape is made in such a way to help us adapt to climate. Despite the fact that sometimes people tell you that you have the same nose as your mother or your father, they are wrong. Your nose shape has an important job in your system and it is made this way to help you adapt to the environment.
This new research was conducted by a team of scientists from Pennsylvania State University. They discovered that the nose shape is different from place to place. People born in cold places have a different nose shape than people who live in warm places.
This is our way to adapt to the climate. The researchers discovered that people who live in warm and humid climates have a wider nose. On the contrary, those who live in cold and dry places have a narrower nose. The findings show that the climate we live in shapes us too, not only genetics do.
“The positive direction of the effects indicates that wider noses are more common in warm-humid climates, while narrower noses are more common in cold-dry climates,” said Mark D. Shriver, Professor at Pennsylvania State University.
The researchers observed that people in cold places need a narrower nose so that they could alter the airflow in order to become warmer and more humidified. Since the air is warmer and more humid there, people who live in warm climates can have a wider nose. They don’t need to alter the air.
Researchers also observed that people who had a narrower nose shape and lived in colder climates were more likely to have more children than those with wider noses. This shows, once again, that every creature on Earth has a way of adapting to the climate.
What is your opinion about this study? Did you know that climate was the one that shaped our noses?
