What is the Real Purpose of Armpit Hair?
The other theory is that it's just a signal of maturity. I don't buy that one because you can begin puberty as early as six-years-old these days. Is that really mature? Is that an age that should be signified to people that you're ready for sexual intercourse? I DON'T THINK SO! So there goes that bullshit theory. So what's the evolutionary purpose? My personal theory is that it's extra hair that can be cut out and used as insulation or fire kindling in survival situations. If your underarm hair is as long as mine it can even be used to make ropes. Finally my "genetic defect" can be a benefit!
