Question about evolution?

Question

I was always curious as to why evolution gave us hair and eyebrows. Some say it was in response to the elements or the climate. How come different textures and colors then? How come evolution gave women a figure unlike men? It has no physical consequence, except cosmetic. was that important to the survival of the species?

sweat also runs down your leg and @ss sweety.

you must have really wide eyebrows.

why are you only focusing on the pelvis area?

men have bigger hips than women. women only appear to have bigger hips b/c of the small of the back. r u kidding me? its that curve that i am reffering to.

once again im not talking about the pelvis and breasts. im talking about the curves. mens hips are bigger. the pouty lips, the curvy legs, which have nothing to do with birth.

Answer 1

Exactly. Good question. But it's unanswerable if you want a logical explanation. The only possible thing to say is that it was a MAJOR coincidence. But it's not true- evolution, scientific as it may seem, actually is also proved wrong by science. Scientifically, the odds of every molecule of everything that's ever existed being put together so well... science says that those odds are impossible to achieve. So, in the case of evolution, science completely contradicts itself.

Answer 2

No physical consequence except cosmetic?? The purpose of breasts is to feed offspring. The purpose of wide hips is to provide enough space for the offspring to move through the pelvis enroute to being born. The body of a woman is all about survival of the species!

Answer 3

Each of the characteristics you mention has an evolutionary explanation. Cosmetic differences are highly selected. Human males like to breed with broad-hipped women because they give birth more easily, and eventually this gets built into the human mate selection process and guys start to think it looks good, too. Same for hair colors and textures -- there are initially survival advantages then they become used as cues in mate selection.

Eyebrows stop dirt and sweat getting in your eyes -- try shaving them off and you'll find out. Head hair keeps your head at a more even temperature in hot and cold weather.

Answer 4

It didn't. It reduced hair that covered our ancestors.

Why is a harder question because hair isn't preserved and so it is impossible to tell when humans started loosing hair. It may have allowed humans to shed heat more efficiently in the savanna (if the savanna was their primary hunting ground) or it may have allowed them to move more efficiently in the water (if lakes and streams were their primary hunting ground). Still, it's a open question that may never be answered definitively.

The female figure is an amalgamation of things. The pelvic area is designed for giving birth to large headed babies. The fatty accumulations are designed to store energy. The location of those fatty accumulations is the product of sexual selection.

If nothing else, it provides the ultimate excuse for all girl watchers - we can't change now, we've liked T&A for millions of years.

Answer 5

Actually, we've been losing our hair, for the most part. Check out other primates.

The differences in skin tone can be correlated with native latitude -- the amount of sun received.

The difference in women and men is vital -- women are the child-bearers, and as such need wider hips and (as mammals) large mammary glands. Since the female is somewhat incapacitated from her burden, muscle isn't so important -- she's vulnerable either way. The male, however, was a hunter and defender, and thus has a more powerful structure (in general).

Answer 6

im sure if you looked at the early human form... they were very course and unrefined....men or women... very brutish forms...short and stocky. nothing like we are today.
but your question... really reflects why all animals have differences between the sexes....most birds for example have differences in the plumage...male birds...bright and flashy to attract a mate...female birds... dull feathers to better hid in a nest. so im sure as the ages have passed...we have adapted to our envoirnments.... where there is alot of sun... we have darker skin to protect our skin... where there is little sun... we develop blond hair and pale skin because its not a needed protection..asians and eskimoes have thick eyelids to help save their eye from wind and snow and sand
so itsall around you

Answer 7

By physical consequences I'm assuming you mean for survival, by natural selection. Darwin recognized that another aspect of evolution was sexual selection - the preference expressed by one sex for characteristics of the other which offered no survival advantage (the peacock's tail, for example). There are arguable survival advantages to the characteristics you mention but they're as likely to be sexually selected than naturally. Other sexually selected human characteristics - that is, they were chosen in mates for breeding for purely "cosmetic" reasons rather than anything else would include breasts (no other ape has them as large as humans) and penises (likewise - the silverback gorilla packs an un-mean one inch). See, size does matter!

Answer 8

Why is not the right question. Evolution is a reflection of mutation in a competitive environment. Changes often survive because the offer an advantage, but sometimes simply because the offer no disadvantage to the passing on of a gene.

Answer 9

Err...lots of animals have different color hair. Evolution DOES favor cosmetic things. You are more likely to breed and pass on your traits if the other sex thinks you are hot. I think you can figure out the rest from there.

Answer 10

I'll ask God when I see him. I don't think the theory of evolution answers questions. I think it make more. Which was first male or female. How did lungs come about? How did a microbe become more complex?
