We don't use 10% of our brain, any neurologist with a Ph. D. will tell you that. We use all of the parts of our brain, just not at the same time, since firing all neurological impulses at once can cause brain damage or even a stroke.
If we did use 10% of our brain, we would be incapable of doing anything, we wouldn't be able to speak, listen, think or remember.
Forgive me for not clarifying. Yes, we use all the different parts of our brain, all the different sections and lobes. What I meant was that we cannot FULLY access the potential capabilities of all the different parts and functions of the brain. What I meant was that if you take all of the brain functions we can access, both subconsciously and consciously, and put them together, it'd only still be about 10% of the entire brain.
Of course, I know that you cannot access the whole of the brain simultaneously, for the exact reasons you stated above. What I meant was that as a whole, human beings are only capable of accessing 10% of the brain's POTENTIAL ability. As a whole.

how can we evolve when the technology and medical discoveries we have come up with are hindering it. if you think about it, since we can cure so many desieses then the whole survival of the fittest cant work. if the "good" genes cannot be passed down and the "bad" ones are kept in the genetic pool then we can NEVER evolve, at least phisically. Now, mentally, that's another matter. we have been gaining knowledge, and for one you can say that our ways of life and the ways we apply the knowledge are evolving. we might be getting smarter and maybe that is the fated way humans have to go toward
[color=green]I covered that in my second possible answer to the question "why aren't we evolving anymore."[/quote]

if we are evolving, we are doing so by losing teeth generation after generation, having genetic conflicts when interbreeding with people from different countries (as for example, im half italian and half american and my teeth dont fit in my jaw lol)
That's not an example of evolution, no. There are no genetic conflicts between people of various races and "interbreeding." You being half italian and half american (i suppose you mean american indian?) is NOT the reason for your dental problems. I am half italian, the other half comprised of scottish, english, polish and native american descent, and I have no strange physiological problems, so the idea of "genetic conflicts when interbreeding" goes right out the window.
The genetic difference between people of various nationalities is very minor, when considered against the whole of the race. Things like skin color, hair color, hair texture, etc, are all determined by a minor one or two genes in the body that can be evolved rather rapidly. The possibility of having a genetic "conflict" is slim to none.

no we didnt evolve from chimps, chimps and humans evolved from a common ansestor accorting to scientific findings. i mean hello, we have a common ansestor with bugs! people get confused because humans and chimps have a great deal of genetic info in common.
That's more or less what I said in my post....that we evolved from, and I quote, "a relative of the modern-day chimpanzee." I simply said "chimpanzee" during most of my post because I figured it would be easier than saying "a primitive version of the Pongidae pan troglodytes."
But yes, you're correct. The modern-day chimp and the modern-day human both evolved from a common ancestor. The only difference is that the modern-day chimp underwent very little evolutionary activity in the past 5 million years, whereas us humans underwent a substantial amount of evolutionary activity.
We don't have a common ancestor with bugs, but we do have common ancestors with organisms similar to the amoebas that you could scrape off the inside of your cheek.

the defenition of evolution is A gradual process in which something changes into a different and usually more complex or better form. it says better not worse.
That's the generic, basic definition of evolution. In this instance, evolutionary biology, the definition of evolution would be "change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species." By common sense you would figure it would be a better version of the specie. But we are not evolving into a "worse" version of homo sapiens sapiens. We're just evolving into a "different" version. We both share common grounds in the fact that you and I both believe that human beings have stopped or considerably slowed down human evolution on the physical level. I nowbelieve that we are beginning to evolve on the mental level.
An extraordinary example of this, though fictionary, would bein the movie "The Time Machine," based on the novel by Jules Verne. Human beings forced themselves to breed into select castes focusing on different traits. One caste focused on evolving their physical abilities, another their mental abilities. I believe human beings are going to start evolving towards the latter....our brainpower will continue to evolve while our bodies physiclaly do not.

another factor involved is that humans will change the enviornment to suit their needs. if evolution occurs to adapt to the enviornment how can it happen when the enviornment is manipulated by humans?
I already addressed that point in the very first possible answer to the question of "why have humans stopped evolving?" Humans are capable of manipulating our environment to suit our bodies, and therefore evolution has been halted or slowed, for the time being.
