The less ecologically rich environments of Europe and other non-tropical ecosystems when compared with the more varied and complex landscapes of tropical Africa can be convincingly argued to select for reduced levels of fine discernment and/or complex reasoning ability in various homo species. Evolutionary evidence relating to Homo erectus, for example, suggests that the further he traveled from equatorial Africa the lower his cognitive capabilities became in contrast with those of other erectus lineages that remained in Africa or closer to the African continent. The lineages of Homo erectus, in fact, can be hierarchically arranged in descending order from the most behaviorally complex to the least, based entirely on its lived distance from equatorial Africa. 1) Homo sapien sapiens remained and evolved in tropical Africa and is the most behaviorally complex 2) Neanderthals would evolve in ice age Europe, and 3) Peking man evolved in East Asia.
