I think we have grown into what we are today, I dont believe we evolved from apes but I do believe there is simply a very strong resemblence. our brain might have been at a similar level but then so is a cats to a dogs, a whale to a shark and a rat to a mouse.
No-one is claiming that humans evolved from modern apes. That's a strawman from some creationists. The idea is that modern apes and humans evolved from a common ancestor, a very long time ago.
I think we have always been humans, even as cavemen we was never described as apes, the person to have invented the wheel certainly wasnt an ape.
Humans (and pre-human hominids) never really were "cavemen", but that's besides the point. The hominids you refer to existed long after the split I refer to above and the wheel was invented long after that.
when a species evolves, the whole species evolves, not a segment of it.
Why?
in argument though you can compare the sub catagories to seperate, compare a black man to a white man and you can easily see different features. this is the equivelant of comparing types of horse, there are types of human of which are by coincidence seem to originate from particular parts of the world.
Which subcategories are you refering to? Minor variations in features are just that - minor. Skin colour is an obvious adaptation to local enviromental conditions by varying melanin production - less melanin provides a slight advantage in conditions of less sunlight, more melanin provides a slight advantage in conditions of more sunlight (UV exposure rather than sunlight, to be accurate).
whether evolution depends on where you are in the world or not I do not know
It does, because that determines enviromental conditions. Melanin is an easy example - it's a UV filter. Ideally, a certain amount of UV should penetrate the skin - it's good for you. So in parts of the world which commonly have relatively high levels of UV exposure, it's beneficial for people to have very high levels of melanin in their skin, to try to filter UV down to optimum levels, but in parts of the world which commonly have relatively low levels of UV exposure, it's beneficial for people to have very low levels of melanin in their skin, to make the most of the small amount of UV. It's also beneficial to be able to vary melanin production in response to seasonable variations in UV exposure - a suntan.
but it does bring up new questions. apparently all life is meant to have originated from africa. and yet to the north of this is the sahara desert, the most dead of all deadlands.
It's there now, but it wasn't back then. Even in recorded history, it was far less harsh than it was now. Even if it had been as bad, some people would still have striven to find out what, if anything, was on the other side. People are like that.
to answer the evolution of ourselves - I would like to think we are getting more evolved over time but I highly doubt it as what proof is there?
Archeological remains. Genetics. It's all evidence, not proof.
I cant see us changing thinking about it. look at the apes, gorrillas, dolphins, seaguls, the platupus, penguin and many other creatures we dont so much have data on. admittedly we havent studied long enough to be able to prove the evolutionary theory, but we have been around since the stoneage, and all that has changed is what we have learned and not us ourselves.
Humans are a relatively long-lived species and in recorded history they have generally adapted our environment to suit them rather than vice versa and/or used their intelligence and tool-using ability to construct protection from the environment. In other words, humans have acted to stop human evolution in physical terms. Given that and the relatively short time-frame you're looking at, it's no surprise that you don't see physical changes in humans.
