A Darwinian Perspective
In evolutionary history, no two sub-species have ever been able to cohabit a limited ecology. The outcome of this inherent selective conflict is written in the history of the human genus Homo, that is, the successive increases in brain size and intelligence and the disappearance of earlier, less corticalized forms of Homo. Civilization will eventually be shaped by the domination of Homo sapiens sapiens.

CONDITIONS OF INTERNATIONAL SURVIVAL
Twenty-First-Century Adaptive Shift
From the standpoint of our evolutionary knowledge of the pulsations of expansion and decline of the larger taxonomic units involved in evolutionary change, as well as species and races, the sub-categories of the larger evolutionary exemplars, our recent five hundred years on a roll of expansion and multiplication is not atypical. All life forms tend to take advantage of even momentary adaptive opportunities for a possible surge into dominance. Their movement is explicable as an attempt to preempt an ecological, morphological, or behaviorally adaptive niche, and grow in both size and in number.
