Climate change, neoneanderthalic change due to related archaeal overgrowth and homo neoneanderthalis evolution. Neanderthalic human endosymbiotic archaea and its archaeal RNA viroids secreted hybridises with human HERV sequences immune and metabolic sequences producing formidable covid19 virus from which homo neoneanderthalis the predator is protected but can infect the victim homo sapien species and can massacre it to extinction over 2-3 years producing a dominant world of neoneanderthalis. Climate change related neanderthalisation of the species leads to a flood of civilizational diseases. The neoneanderthalic victory is pyrric and they will become extinct as before. The growth of archaea in the sea beds and methanogenesis leads to flash catastrophes leading to ocean earth quakes, rising sea levels and world sinks into anonymity and obscurity. An intergalactic quantal computing archaeal cloud controlling the universe producing even a possible extraterrestrial origin to the pandemic.
