I read a couple of paragraphs. Is one thing to do a study on rats then to do a study in humans. This doesn't disprove my claim.
Edit: Also, it seems that you are implying that the differences are so huge that we should have a lot of retarded people walking around us. The proof that the gaps in intelligence are small should be obvious by simply looking at your environment. There are people getting phd's from all corners of the world. China, Japan, USA, Mexico, Europe, Africa, Australia. How did those same genes that enable people to get phd's get to places so far away as China or Japan which have been isolated for so long? Even for thousands of years? The thing is that those genes have been there all along for thousands of years.
I think I already agree that there are differences but I do not agree that the differences are huge. Otherwise some of these groups of people, like china or japan who have been isolated for thousands of years, would have serious intelligence differences as the rest of us.
Another example is the Mayans, also isolated for thousands of years from Europe. Independently invented the zero and developed a Mayan calendar unequal on precision until recently. Many of their descendants have gone on to get PHD's. If there were really large differences then some groups of people would not even be able to get PHD's.
Again, the there are differences but they are tiny. Yes, there are studies saying that there are huge differences between groups of people but frankly many of these studies are questionable and sometimes they almost seem to carry a hidden agenda.

Have you read the literature on IQ? These differences exist, whether you will accept it or not is a different question.
