Im sure you all know that if you get your hair wet on a cold day, and youre in a position where you cant get indoors, you might actually die if youre left long enough, if thats the case then why dont Europeans or and other cold weathered people have the hair that most Africans and other warm climate people do that doesnt really absorb and hold as much water as straight hair, this doesnt make sense to me. can anyone clarify this for me?How does evolution explain the need for hair dryers?
People solve this problem....by not bathing. Seriously, in areas where there is little heating and/or no hot water, people just stop bathing until the weather warms up again. It occurs in some remote areas in the mountains of Europe still, and did in the past; most notably, in my mind, during the siege of Leningrad.
Hygiene hasn't been that big of a deal until plumbing. In some ancient cultures (like Greece), people would only bathe twice a year; if that often. While our hair may get wet from rain, our heads can still be covered by what clothing we wear to protect us from the elements already, and it can be dried rather quickly in shelters with fire pits. As our species became skilled at making fires and clothing, hair wasn't much of a necessity anymore, which is one of the main reasons we lost it everywhere but a few select places. The hair on our head can do many things that are beneficial to us, like absorb sweat and protect our highest spot from sun damage, as well as be sexually attractive. These benefits outweighed your wet -hair conundrum, if it was much of a deal to begin with before we started bathing regularly.How does evolution explain the need for hair dryers?
Make sense, will clarify.
Humans have evolved intelegence/ common sence to tell them not to do stupid things like getting their hair wet and then going out into sub zero temperature, it would afterall only be under extreme conditions in which anyone would die, and they would probably have a disadvantage that lead to this. This fits in with survival of the fittest maintaining the population.
Europeans have dense fine hair for insulation, africans thick hair to allow for rapid evaporation which removes excess heat from the body.
Interesting what some people consider necessities. How did humans survive prior to the invention of electricity? Death by wet hair...O.M.G.
As much as evolution has being rammed down our collective throats, no missing link between one species to another has ever been found. As many people have asked, if man evolved from monkeys, why are there still monkeys? People are bigger now, mostly due to much improved medicines and diets. That's not going to change the type of hair you have, or the number of digits on your hands or feet.
Its not evolution, its vanity.
Such hygiene is a recent concern for humanity.
