@kawwaixw: Another requested video + Most people think straight hair only evolved to trap heat and repel freezing rain but that’s only half the story. If it's just for freezing climates, why do we see indigenous populations in hot, humid tropical rainforests with completely straight hair? The truth is, evolution isn't a perfect rule book. Watch the video to see how straight hair handles both freezing sleet and tropical humidity, and why genetic drift plays a massive role. The EDAR gene mutation didn't just affect hair. In genetics, this is called pleiotropy—when one single gene controls multiple, completely different traits. Harvard and Broad Institute studies found that the exact same genetic switch that gave East Asians thicker, straighter hair #evolution #humanbiology #straighthair #genetics #fypdongggggggg

It depends on your genetic and how you treat your hair.

Actually hot humidity favors tight curls which is seen in Africans who also live in hot humid climates. Then again natives from the Amazon have straight hair. Adaption never follows a pattern that's just simple black and white. There's no rule like "oh it's cold climate now evolution will give you straight hair"

Straight hair actually adapt to dry dark cold regions. sstraight hair give out more UV raise on your scalp and also distribute a good amount of natural oil easier. While keeping your neck more insulated.😁

Люди реально не знают что с прямыми волосами намного жарче летом чем с кудрявыми и наоборот. Африканцам например нужны настолько кудрявые волосы что б была вентиляция и защита от солнца. У меня прямые волосы и моя шея буквально горит с распущенными волосами. Более волнистые или пористые волосы больше нужны влажному климату
