The Intelligence Divide: A Contemplative Survey of Human History

The author rejects a recent African origin for homo sapiens sapiens and argues that the sub-species' explosive development in intelligence was a Darwinian response by a migratory population domiciled in the challenging climatic conditions of Northwestern Eurasia. The history of Homo s.s. intelligence, and especially of Caucasoid intelligence, is traced, and the spread of Homo s.s. genes into other world populations is charted, with particular attention to the flows of genes into predominantly Mongoloid populations. In conclusion, the article contrasts the success increasingly enjoyed by the Northeast Asiatic intellect against the question mark that hangs over the survival of Western Caucasoid intelligence.
