Why do you still refer to the lack of invention as the proof that they are behind.
I have already given an explanation. You still choose to ignore my previous statements .
Its as if I'm talking to myself.
You could say something like "Whoa chikky , major logical fallacy..." or "I think you are wrong because x,y,z.."
But don't just ignore me.

Mutations do not occur because of any other reason than that they are random so no continuous friction will change your genome.
Once a mutation has occurred however there has to be a method for selecting this gene for the next generation.
This method happens by way of preventing those without that gene from breeding usualy those without the gene would not be able to survive to the age where they procreate.
If there is no method for selecting genes then the those without the gene will still be able to compete with those without the gene.
That is why it is called "natural selection" and not "continuous friction"

This is why blacks have much smaller brains
------------------
Black people have smaller brains than other races because they have smaller bodies.
People living in cold environments have larger bodies because this minimizes their surface area to mass ratio .
This means they will not lose heat as fast.
What counts however is the brain to body mass ratio otherwise elephants would be considered more intelligent than us.
A point to consider is the Neanderthals who had larger brains in terms of cc's and we all know were they went.
Neanderthals are not our direct ancestors but are a branch of humanity that just got extinct.
Another point to consider is that noone doubts Africans intelligence in such things such as sport and music.
These intelligences , whether emotional or not, are still a function of brain size.
If we can have smaller brains and still be just as good in music as everyone else then why cant we excel in other endevours that are also a function of brain size.
Emotions come from glands in the body .They could be driving us to particular types of endevours but that only means that we need something to drive us to do philosophical works and not larger brains.
There is also the common misconception that races that lived in cold environments needed greater intelligence to over come their environment and so those members of those races who could not cut it out were forced into extinction.
This veiw would look true and maybe obvious to some but as we shall see this ism not the case.
There have been two main migrations from Africa in prehistory.
The first was the homo erectuses .They had reached as far as java.
Despite these people meeting harder environments than any that was in Africa they never developed into anything
They just got extinct.
In fact it was left up to the African homo erectuses to develop into early homo sapiens.
These people also migrated out of africa and had reached as far as Britain 200 000 years ago as evidenced by the swanscombe skull as well as others.
Now these people, who had foreheads very similar to us, were to go through some of the harshest environment by going through the ice ages.
You would expect that this would urge these migrants on to greater evolutionary hights but as we shall see this did not happen.
When examining the fossil record it is seen that their brain mass did increase , however their brain to body mass ratio (which is what counts ) stayed approximately the same. What could be seen as well was that their foreheads receded more and more with time , almost as if they were trying to go back to the homo erectus stage.
These people became later known as the Neanderthals.
Clearly there is an error in assuming that these conditions are the ones necessary for fostering intelligence.

shley Montagu long ago pointed out that Swanscombe man, who was quite modern, preceded Neanderthal, and that a Swanscombe type was found at Quinzano, Italy and placed in the Middle Paleolithic. Also before Neanderthal came Fontechevade man, with cultural remains, and he "would appear in all respects a modern type of man." [11]

The final migration was that of modern humans who went out to conquer the world.
Through all this we can see one common thread.
Hominids evolve in an African climate , leave Africa , then either go extinct or evolve backwards.
What then made us who we are?
The answer is here if you take a look at the following site.
http://books.google.com/books?id=5Y4dJo ... Y#PPA17,M1
and
http://laughingmeme.org/2007/09/12/aida ... ive-towar/
This site talks about the social evolutionary principle by which humans got more and more intelligent.
Intelligence is shown in the very human act of sharing. It was also important for a hominid to know the effects or what would happen if he offended the alpha male , two days after he had last eaten , In the middle of the dry season and while the majority of the females were on heat.
This last example shows how the hominids were forced to think in terms of many variables in order to exist as a group.
Failure to do this would often result in the offender being a cast out and so his genes would not get carried on to the next generation.
When looking at the migrations it can be seen that the hominids that left Africa would have been less than those that stayed behind so the social pressures would not be as great as those in Africa.
They would also not have the luxury of "casting out" a group member because they needed all the manpower they could get to survive.
When the proto Caucasoid/mongoloid people left Africa they would have been less than the africans so if anything those people that stayed behind would have grown more intelligent with time until the others had a chance to catch up.
There is another point to consider .When the proto Caucasoid/mongoloid people left Africa they would have encountered the last of the Neanderthals and with the inevitable interbreeding that occurred there would have been a decrease in intelligence.
When comparing men and women we see that the main difference between them is that men have higher levels of testosterone.
In fact , giving testosterone to women makes them more manly , They develop an Adams apple , deeper voice and even a beard.
The point i am trying to make is that if white women have not produced as many philosophers as white men then it is testosterone that is to blame. Now black males have higher testosterone levels than white men so this should mean that however white males differ from white females , black people accentuate this difference. So this should mean , by transitivity , that black men would have had more philosophers if they had had the same chances.

Steele has found that he can completely erase the black-white differences on such tests by convincing students that the particular test they will take is not related to intelligence. Conversely, he can recreate the racial gap by an intervention as minor as having students indicate their race on a questionnaire

Could you also explain why the two most intelligent creatures after humans come from africa.
