The brain which is regulated by endosymbiotic archaea consequent to global warming has its structural anatomy changed. The frontal lobe &pre-frontal lobe concerned with forming large social colonies and grand civilizations based on religious, political, and scientific ideas shrinks and atrophies. The part of the brain called cerebellum becomes more dominant producing a cerebellar cognitive affective disorder. This creates a population which is creative, delusion, hallucinatory, spiritual, anarchic, anti-establishment, restless and deglobalized. This produces neo-neanderthalisation of the human society. As the archaea catabolizes cholesterol for its energetics there is very little cholesterol for sex steroid metabolism and the population becomes sterile, asexual, alternate sexual and digisexual. The population number falls. The population become autistic and are homebound. They are creative and not able to relate to other people and live in world of void. It is an unnatural unreal world of solo individuals living like hermits in solitude with computers, games for entertainment and computers for digisexuality. Such small autistic asexual cultures deglobalized the world.
