"There are two important factors to consider in the emergence of social change. One is that a society develops through changes in its institutions, which are blends of culture and genetically shaped social behavior. The other is that the genes and culture interact. This may seem paradoxical to anyone who considers genes and culture to be entirely separate realms. But it is scarcely surprising from an evolutionary perspective, given that the genome is designed to respond to the environment, and a major component of the human environment is society and its cultural practices."

"The recent discoveries that human evolution has been recent, copious and regional severely undercut the social scientists official view of the world because they establish that genetics may have played a possible substantial role alongside culture in shaping the differences between human populations."
"I think the subject of race has been so difficult and so polluted by malign ideas that most people have just left it alone, including geneticists. … Most genetic variation is neutral – it doesnt do anything for or against the phenotype, and evolution ignores it – so most previous attempts to look at race have concluded that theres little difference between races. I think this position is the one on which the social scientists are basing their position. … If you look at the genes that do make a difference, selected genes, which are a tiny handful of the whole, you do find a number of differences, not very many, but a number of interesting differences between races as to which genes have been selected. This, of course, makes a lot of sense, because once the human family dispersed from its homeland in Africa, people faced different environments on each continent, different climates, different evolutionary challenges, and each group adapted to its environment in its own way."
"The fact that human evolution has been recent, copious and regional is not widely recognized, even though it has now been reported by many articles in the literature of genetics. The reason is in part that the knowledge is so new and in part because it raises awkward challenges to deeply held conventional wisdom."
"The classification of humans into five continental based races is perfectly reasonable and is supported by genome clustering studies. In addition, classification into the three major races of African, East Asian and European is supported by the physical anthropology of human skull types and dentition."
"Many forms of new knowledge are potentially dangerous, the energy of the atom being a preeminent example. But instead of curtailing inquiry Western societies have in general assumed that the better policy is to continue exploration in confidence that the rewards can be reaped and the risks managed. It is hard to see why exploration of the human genome and its racial variations should be made an exception to this principle, even though researchers and their audience must first develop the words and concepts to discuss a dangerous subject objectively."
"The idea that human populations are genetically different from one another has been actively ignored by academics and policy makers for fear that such inquiry might promote racism. The argument offered here is that people the world over are highly similar as individuals but that societies differ widely because of evolutionary differences in social behavior. It would be better to take account of evolutionary differences than to continue to ignore them."
