Neanderthals, race and psychiatric disease

Explaination

The race aspects of the Neanderthal theory, while a logical consequence of Neanderthals hybridization mostly in Europe and Asia, is regarded as "politically incorrect" by some people, and provoking on others. Still, if this part wasn't true, neither would the theory. Therefore, I've decided to describe separate from the rest.

Creativity and inventions

Today, inventions coming from Africa are still unusual, and the new leading countries are in Asia and South-America, and not in Africa.

Life history or r/K selection

Among various animal species, researchers have studied r/K selection. r selection occurs in erratic environments, like on the savannah, where sudden drought is common. K selection occurs in predictable environments, like at higher latitudes. JP Rushton and several others have studied this in humans. There are several indications that Africans are the most r-selected population, while Asians are the most K-selected. In fact, people with autism and Asperger show even more K-selection, and if treated as a separate group, would fall at one extreme, with Africans at the other extreme.

Here are the results:

1. Africans have lower average IQ and smaller average cranial volume. There are studies that confirm that autistic children both have larger cranial capacity and IQ. Most importantly, the group with IQ lower than 70, identified with classical autism, is much smaller than the Asperger group. Mean IQ south of Sahara is believed to be 70.
   
2. Africans mature faster. There is lots of evidence that autistic people mature slower and longer than NTs.
   
3. Africans are more sexually active, and less faithful in relations. Many Asperger-people have disinterest in sex, and are extremely faithful.
   
4. Africans have better motor performance. "Deficits" in motor performance is part of the Asperger diagnosis.
   
5. Determination. Africans are more "impulsive". Special interest and extreme determination is part of the Asperger diagnosis.
   
6. Creativity. Africans have no history of creative inventions. They hadn't even invented a written language nor many other basic inventions. There is no ancient civilizations south of Sahara like the one's in Egypt and Eurasia. Egypt most likely was founded by outsiders (Caucasians). Asperger is related with creativity.

Most, if not all, the differences between races would disappear if we were to exclude people with autistic traits in the studies.

Rushton tries to explain these differences by selective pressure due to habitat. However, modern humans have only been subjected to this selective pressure for at most 30,000-50,000 years. Neanderthals and Asian Homo Erectus had been subjected to them at least 10 times longer. Therefore, we must either assume they were 10 times better adapted (no interbreeding), or the adaptations are due to interbreeding with them.
