The Intelligence Divide: A Contemplative
Survey of Human of Human History.
Seymour W. Itzkoff
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.
