What is the point of "goose bumps"? What is their purpose?

Similar questions: point goose bumps purpose.

Evolution and fur Back in the old (old, old, OLD) days, man's predecessors had fur. Goosebumps occur two times: a) in cold--the hair follicle (which is the goose bump) clenches and raises the hair, creating a small air space warmed by body heat trapped between the skin and the fur. This helped to warm 'us.' b) in fear--when the hair follicle raises the hair, it makes 'us' look bilkier, stronger, and--with luck--scraier to an enemy.

The enemy might be less likely to attack. That's all there is to goose bumps, at least as far as I know. They are simply one of many little 'proofs' of evolution.

No purpose any more In animals other than humans, the goose bumps make their fur stand on end. That keeps them warm (because it traps air against their skin, like fluffing up insulation) or makes them look bigger (by making all the fur stand out. ) We are mammals, but our "fur" is far too fine to really keep us warm or make us look terribly impressive.(Well, I've known some men...) But we haven't lost the goose-bump reflex: the muscles still contract, making our pitiful little hairs stand on end.(It might keep us a tiny, tiny bit warmer when we're cold, but it's sure not scaring anybody when we get stress goosebumps.) Since it's not doing us any harm, we keep it.

But since it's not doing us any good, we may some day lose it.("Some day" on evolutionary time scales, a million years from now. ) It's called a "vestigial reflex". Ccups may also be vestigial reflexes..

My understanding is that... goosebumps are actually a contraction of the skin, forcing the hairs to raise up, providing slightly more protection from the cold. This is why you get them when sitting under an air conditioning vent. en.wikipedia.org/wiki/Goose_bumps .

Goosebumps are normally related to sensing a decrease in temperature The goosebumps are actually the hair folical being pulled so that the hair is standing perpendicular to the skin. Normally hair lies relatively flat, very close to the skin. There is very little air between the skin and the tips of the hair.

Getting goosebumps causes the hair to stand straight up. Now there is a lot of air between the skin and the tips of the hair. This air is relatively trapped by the hair and will help retain the body’s heat.

The hair will diminish the amount of cold air from the outside from replacing the air near the skin that has been warmed by the body. Obviously it is not very effective in the wind without a jacket, but the body does what it can.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
