Climatic change & Sapien World of Reason vs. Postmodern Autistic World

The homo neanderthalis had a cerebellar dominant brain and a philosophy of intuition, subjectivity and magical realism consequent to archaeal endosymbiosis. Retroviral symbiosis in sapiens led to evolution and expansion of neocortex resulting in scientific temper, reasoning and logic. The evolutionary biology of neurophilosophy depends upon symbiosis and brain development. Neoneanderthalisation due to archaeal symbiosis and climate change results in development of a cerebellar dominant brain leading to a postmodern philosophy of magical unreality. The homo sapien civilization because of the brain of logic, scientific temper and reason became the grand civilization dominating the earth.
