why the hair of the arm of the mountain gorilla are epically long than other hair body ?

hair growth is primarily involved in protecting underlying structures, and for the purposes of keeping warm.  Gorilla's have hair all over and some maybe longer, if it is the arms this would indicated they are vulnerable parts exposed to trauma and cold.  we too are covered in hair but most of it is very short.  we have evolved our hair pattern to provide protection to our vulnerable areas...such as the head, the genitals, the arm pit, eyebrows.  however many men have hairy chests too, they dont need protection here anymore but evolution hasnt caught up with us yet...and maybe it serves as attaction feature for females.  Hairyness is related to high levels of testosterone so u should thinkabout that fact too...testosterone fueled males are more attractive to females

I think long. There's some people short hair just doesn't look good on...he's one of them.(so am I, so I can relate) He does resemble a caveman a bit when he grows it too long though... OH I KNOW! Grow it long but cut the facial hair... Then he's look like a actor or something! Lol

Did you ever notice the diameter of an Asian person's hair?  It is thicker than a Causcasians.  I am sure the sheer thickness has something to do with it.

thier unique adaptations..bacuse they dont ahve a long neck..god gave thema long trunk..

almost exectly half  a metre, some times a litle bit less .sometimes a little bit more.depending on the age and the region\nthe elephant is fatter and longer(one metre) even though the girafe is taller\nso this goes to prove that the lenth of the neck does not determine the length of the penis.

I think what you are referring to is "natural selection" aka "survival of the fittest"\n\nBasically the animal most suited to its environment due to mutation (the ones with genetic proclivity to have longer necks, stronger arms etc) will get more food/mates and will tend to, over a long period, tend to make the species move in that direction.\n\nBasic answer - if you need more drop me a line.

We have a horny (keratin) protection on our last phalanxes because we're mammals and almost all mammals have (except for whales and some others); it's something we probably inherited from our synapsid ancestors ("mammal-like reptiles"). \nAnd we have fingernails instead of claws or hooves because we're primates. All great apes have fingernails, whereas "lower" primates have claws. \n\nAt least, that's the evolutionary reason. I'm sorry if you were looking for something more philosophical!

wtf didn't jesus have long hair?

In contrast to most mammals, humans do not have an all-embracing intense hair on their body. Several theories have been advanced to explain the bareness of human body hair. One suggests that nature selected humans for shorter and thinner body hair as part of a set of adaptations including bipedal locomotion and an upright posture. There are several problems with this savanna theory, not least of which is that cursorial hunting is used by (other) animals that do not show any thinning of hair, and that hair similar to chimpanzees and gorillas also shades the skin from radiant heat and protects it from hot winds, and thus another mechanism for heat loss is not required. Another problem is that bipedal locomotion apparently now predates hominids moving from a forest environment to a savanna environment. A more recent theory for human hair loss has to do with a possible period of bipedal wading in a salt marsh in the Danakil region of Ethiopia, possibly occurring in the hominid lineage between 5 and 7 million years ago. As a wading animal, it was more efficient to develop short body hair and a layer of subcutaneous fat for streamlining and insulation in the aquatic environment; the eccrine sweat glands developed later after the hominids left the water; see Aquatic ape hypothesis. One problem with this theory is that both chimpanzees and gorillas have the same density and distribution of the eccrine glands, but that they have not been developed for sweat production.\n\nA third theory for the thin body hair on humans proposes that Fisherian runaway sexual selection played a role here (as well as in the selection of long head hair). Possibly this occurred in conjunction with neoteny, with the more juvenile appearing females being selected by males as more desirable; see types of hair and vellus hair. The human female body hair typically has more vellus hair (making the skin appear bare), while the male body typically has more terminal hair (especially on the chest, abdomen and back). Thus sexual selection can explain the sexual dimorphism in human body hair, with the results of selection being more evident (more extreme) in the female than in the male, a point which the other two theories cannot address without proposing substantially different behavior between males and females. Also, we see that artificially bare (shaved, etc.) legs, arms, etc. on women are seen as "sexy" even today, while body shaving is not nearly as common for men.

I'm not for sure but I think it is the way that it grows or maybe the fine little hairs that grow on them. This site might help you more than I could.

The palms have different kind of cells compared to those in the back of the hand. The palm has all these fine lines that make gripping an object easier, hair would not have helped that much I think.Plus I guess its an evolutionary thing - imagine the hair in your palms getting pulled at when you do thing! Oww.

do u mean the animal? an aye aye?  it lives in the trees in the rain forest and uses its hands to forage for insects and nectar in the tree tops.  it has huge eyes, it looks similar to an opposum.  but i think the external features which u are talking about are its unusal hand, it is either one hand or both which has a differently shaped finger in each place such as index, thumb, pinkie, each of its fingers are built for a different job ( poking in to get necat etc) , some of them are long and thin and the other short and fat etc..quite an interesting animal.

After looking at all the facts, there can only be one possible answer; let me share these with you. Fact 1:Tarzan grew up in the jungle. Fact 2: Because of Fact 1, Tarzan doesn't know how to use razors. Fact 3:Women dont grow breads Fact 4: Men grow breads. Now after anaylising all the facts, you must agree that the only answer to this question is TARZAN IS A WOMAN!!

Baboons are considered monkeys because they have tails.  Apes like gorillas and chimpanzees don't have tails and therefore are not considered monkeys.

Why do African-Americana's have a bigger twig and berries than Caucasians?\n\nSome questions are better left unanswered.

The hair folicle on our face don't have tiny muscles attached to them.\nOnly the hairs on our arms and legs have tiny muscles that pull on the hair to make bumps apprear on your arms or legs.

This is one of my daughters favorites (its generally funnier if told by a 4 yr old).\n\nWhy do gorillas have such big noses?\n\nBecause they have big fingers.
