Why humans don't come in various shapes, colors, height, width, weight as other species...
You can find bird as small as bumble-bee, you can find a bird with 3 meter wings. You can find that cancer that weighs not more then a small insect and you can find another with 1000 bigger mass.
Primates - from orangutans, to chimpanzas, lemurs... they are so different not to mention the whale differences in size, appareance and the way their body works.
Humans - 5 or 6 most common skin colors, almost no difference in way their body works, very limited height, weight variations ?
What would Darwin say about that ? Why don't we have human specimen 10 centimeters tall and a specimen tall 4 metres.. ??
EDIT : I just realized that someone will come and say "take it to some other forum, spanky". No reason to deprive you from this interesting question.

I think you will understand better why humans did not evolve into alot of species if you know why other spiecies did.
I think there are 2 things that answer your question.
1. Spieces evolved from eachother because an individual with a mutation could have more fitness and could maintain. Species also evolved from eachother because of geographic barriers.
Neither of these things apply to humans.
2. Homo sapiens are rather new, we didnt have that much time to evoluate yet.
I dont think we will evoluate (alot) more tho.
Our intelligence stopped our evolution.

Primates . . .

or do you hold with the "WE DIDNT EVOLVE FROM APES" point of view??
[edit]but even though, think about the shortest vs the tallest people in the world - quite a variety in height alone.[/edit]

Orangutans are orangutans, a chimpazee is a chimpanzee and humans are human, there is a wide variation in characterics between species, but it is a mistake to take this to mean that species themselves should show this variation.

but he missed the fact that humans ARE counted primates
your point is valid but its not what he was asking - even though he DID (incorrectly) use the term species

Originally posted by MCAClearly the broader scale has a wide variation, but I restress that such variation is made up of distinct species, albeit linked through evolution and common ancestors. I suppose humans as a species, as my argument showed, will not in themselves show excessive variation, but humans would lie in the variation which is the primeape branch of evolution.

I suppose between us we have answered his question:
They are different due to species - humans are simply another species in the primate order.
