Until the classical periods, I really don't see the higher forms of our intellect coming into play at all.
What do you mean by the "higher forms of our intellect"?
Even the most average (great wording, I know) person would be more than capable of hunting, trapping, building shelter, etc.
"Trapping" and "building shelter" came very, very late in human development. See Caveman. In any case, it doesn't matter if the "average" individual was able to survive and breed, as long as those who were better at hunting or trapping or building shelters had more viable offspring.
These things don't take much brain power, all they take is learning.
This sentence makes no sense. The ability to learn is more or less the definition of intelligence.
Once you understand it, you can teach it to everyone, so everyone can take advantage of it.
Those who were able to understand it can take advantage of it, yes.
Look at what the average human can do today as far as, say, math goes. I can perform nearly any tasks the ancient Greek or Arabian mathemeticians could, and can even show you for the most part how they arrived at them. Their intellect manifested in the sense of putting things together first, but it granted them not actual benefit, as once the one of them figured it out, it belonged to the entire human race.
What does the development of mathematics within the last 5-10 thousand years have to do with the development of intelligence and subspecies?
Intelligence is a funny thing. I don't think it's quite possible to give a definition that narrow. There is no question that the more capable people lived longer, but were those more capable people more intelligent by the standards we hold right now? I am firmly of the opinion that we did our evolving 150,000 years ago, and our evolution since then has been largely superficial changes to deal with weather.
150,000 years ago, humans did not have total control of external factors affecting evolution. It is arguable that humans today do control most of these factors. That doesn't mean evolution has stopped. It just means that the factors affecting it have been reduced substantially and are now mostly internal. However, this is a recent development. For 10's of thousands of years, the weather was just a small factor affecting the survivability of human offspring.
Because after you get to human level intelligence, you don't need to go further to survive on this earth.
On what do you base this arrogant assumption? Just 50 years ago the prospect of nuclear self-annihilation was a non-negligable possibily.
Here's a question that I have never heard an answer too:
How does Joe-Primitive Man know who is intelligent, and who is not? By what standards does he use?
Joe-Primitive Man's opinion is irrelevant. If anything, it is Jane-Primitive Man's opinion which is of some importance. As in whom she chooses to mate with.
The man who catches the most meat isn't necessarily the man who is most intelligent. What one lacks in intellect, one can make up for in physical strength, ability to work in a group, ability to give commands, ability to take commands, ability to learn, etc, etc. I have a hard time thinking of a situation where a comparison of intellects would ever take place.
One may have superior strength and a good ability at giving commands, but if the commands are based on a faulty plan, the outcome will probably be likewise. Do you have evidence that those who were physically strong but mentally weak were better able to bring home the bacon? If this were so, why don't humans compare well with other animals regarding physical strength?
The thing is, we are more intelligent than we need to be.
Huh? Evidence?
All of these things can be done by a mediocre human intellect.
No they can't. A mediocre human can't produce "a better tool". A mediocre humand can't communicate as much detailed information as one who isn't mediocre. Etc.
Again, how being more intelligent than average be of any practical benefit?
Because it resulted in more viable offspring?
What -reason- would a European or Asian need to be more intelligent than an African?
I believe the term "argument from ignorance" applies.
Also, the pygmy's would fall under the category "exception" and not "rule" It would take too long to be too specific.
Are you saying that all African races are better physically than non-African races, except for the Pygmies?
Our intelligence likely came about as a means to use our hands. Once we were done evolving, we stopped.
Evolution doesn't stop.
I don't believe I have ever seen evidence supporting the idea that we aren't almost exact duplicates of humans living 150,000 years ago.
We aren't duplicates, but in general it is a close call. However, I see no reason that certain subspecies shouldn't specialize in a particular area.
Perhaps in time, we'll need to get smarter to keep up with the ideas that come forth out of our brains, but there are very few concepts we have NOW that the average person can't understand given enough time, much less simple things such as tools and traps and communication.
Again, it doesn't matter what the last 10,000 years of human evolution have resulted in, as it has no relevance. And again, it doesn't matter what the average member of a species is capable of. If that member is out-bred by others, the traits which made this possible will be preferentially propogated.
