The curly hair that many people are born with may actually be a result of our evolution.
Appearing to be much less hairy compared to other primates, modern humans have the largest collection of hair on their heads. well, people why does he have a hair and what is the function of this hair? Scientists encountered very interesting results in a study that pursued this question.
New research by scientists from the US and UK shows that our hair is actually us. by keeping cold proved to be liable. Moreover, your hairstyle had a small impact on how successfully this task was accomplished.
- NOTE: The research is yet to be peer-reviewed and has not been published in a peer-reviewed journal.
Curly hair blocks the heat on the head more:
Scientists working with different wigs on a mannequin in a temperature-controlled room found that the heat in the scalp of the mannequins with hair was higher than the mannequins without hair. less than he saw it.
Comparisons were also made between different shapes, including straight, slightly curly and high curl hair. The shapes of the hair interfere with each other in blocking the heat. almost at the same level it was successful. But especially high curl hairwas better at keeping the mannequin cool. The difference has not been fully shared yet.
These results are also useful for the protection of curly hair in humans from heat. part of his evolution showed it could be. The fact that curly hair does not appear in other mammals is actually a sign that this shape may emerge to achieve higher productivity.
The current state of the research has been published in bioRxiv.
