La majeure partie de l'écosystème mondial est constituée par la population humaine. Les activités humaines de l'ère de l'industrialisation conduisent au réchauffement de la planète, à l'accumulation de gaz à effet de serre et au déclenchement du changement climatique. Cela conduit à une augmentation de la croissance des archées coliques et endosymbiotiques générant du méthane, ce qui accélère le réchauffement de la planète qui prend un rythme propre. Le régime alimentaire de l'homme moderne, pauvre en fibres alimentaires et riche en graisses et en protéines, favorise...

The cause of encephalitis lethargica is debatable. At that time, it was thought to be due to the influenza virus like Covid 19 virus. Later modern theories implicated Streptococcus viridans and Entero virus of the Polio family. There was an influenza pandemic in the world corresponding to the evolution of EL suggesting a cause-effect relationship. The somnolence and fatigue syndrome of EL is similar to the fatigue of Covid 19 infection. Therefore, Covid 19 pandemic can also present with encephalitis lethargica and its catastrophic sequalae. This has been described vividly in the Oliver Sachs...

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...
