did you also know that my skeletal structure is different to a dwarf. by time they do change but not from a crouching position walking an all 4's to standing up and walking on 2 legs.
as for the neanderthal, i'll just quote what prominent authority has said
"Detailed comparisons of Neanderthal skeletal remains with those of modern humans have shown that there is nothing in Neanderthal anatomy that conclusively indicates locomotor, manipulative or linguistic abilities inferior to those of modern man."
While their anatomy does not conclude that their abilities were different from modern man, their anatomy was different.
I mean, look at this:
Surely you can see the difference there.
It is a proven scientific fact human bodies adapt to best suit their environments.
I mean, look at all of the races on earth. People with darker skin generally appear closer to the equator, and this simply because people are more exposed to the sun in those areas.
Melanin is the chemical responsible for black skin in your body, right? When the melanocytes (melanin cells) in the epidermal layers of the skin are exposed to greater levels of UV light, this stimulates their nucleolus to produce greater amounts of melanin-producing RNA. The melanin excreted by the cell as it dies in the latter layers of the epidermis protects against the sun as a natural sunscreen. The more sun you're exposed to, the more melanin your skin-cells produce and the darker the skin you have.
Eventually, your need for melanin becomes recorded in your DNA and gets passed on to later generations, so that eventually, they will naturally have black, melanin rich skin.
Conversely, people near the northern hemisphere have white skin which is more proned to flushing. The red colour comes from the oxygenated hemoglobin proteins in your blood, and the lack of black skin is because of the lack of sunlight exposure in those areas.
Skin colour is just one way by which human beings naturally adapt to their environment. If you need proof of it, just look to Asians, Africans, Europeans and note down the obvious differences that do exist. All of these races adapted, they evolved.
From homo-erectus, to homo-habilis, to homo ergaster, to homo-sapien and homo-neanderthalis to modern man, the same adaptions were happening, just on a much larger and broader scale. Humans were gradually adapting from an ape-like, primitive level to more sophisticated, complex and intelligent beings.

were have i admited it? in which of my previous posts have i mentioned the Neanderthals. i was just using the ice age as an example. and how do you know that Neanderthals lived during the ice age, did some evolutionists scetch up an environment just because they found a pigs tooth.
No... it's called carbon dating.
Usually you allow for an error of around 5000 or 10,000 years when going back as far as the last ice-age (50,000 years ago).
You know how carbon-dating works, right?

are you farmiliar with Henry Fairfield Osborne.
Didn't he advocate evolution?
eselam said:
yes i know this. that is true.
well just why is it that arabs are nor white nor black. no one is closer to the equator than them, and thay have been around for millions or years. just as the africans have been.
Diet also plays a role, not just sun exposure. If you eat a lot of red to orange foods, you will have a high exposure to carotene, which is the protein responsible for yellow-ish skin pigmentation. As generations pass, the need for carotene will be recorded in your DNA, and the RNA produced in the nucleolus of cell membranes will come to produce it.
And also, didn't Africans used to cover their bodies a lot less than those people in the Middle East? They were exposed to more sun, so naturally, their race became darker in order to cope.
