why is there no hair on the lip, or in the ear area? why is a human's fingernail flat? it's apparently genetically beneficial. many genetic traits are tied to other traits on chromosomes that were determined many generations ago. adaptiations take place throughout time. humans dont need fatty rear ends, nor hair on most of our bodies, but it's still there from the past. i could get really theoretical, but i'll keep it simple for now.

No Mammal Has hair on Palm as it is the only part which helps us for holding , gripping And many things. Palm's Structure is not capable for Hair growth as it is very grippe.

Probably a retained trait from when we had a common ape ancestor, and before. Imagine having hairy palms and trying to grip tree branches. I doubt whether you would last to adulthood, so the hairy palms were lost.

Some do and those that do have hair are usually insane. .....and those that look for hair in the palm are even more insane. Do you have any hair in your palm?

evolution, because man uses the hands and has to be dextrous and pliable in order to survive the men/women without hairy palms survived to produce young and the hairy palmed men/women had a more difficult time adapting

It is because the skin is very thick on our palms and soles.

It's an adaptation to help gripping, I suppose.
