Archaeal symbiosis is seen in Aryo-Dravidian Neanderthalic population. The colonic & endosymbiotic archaea also generates RNA viroids which are converted to DNA viroids by colonic epithelial HERV reverse transcriptase & gets integrated into the human genome. The RNA and DNA viroids hybridise with the viroidal and bacterial population of the gut microbiome & virobiome DNA & RNA leading to generation of new emerging viruses like Covid 19. A low fibre diet with increase in protein and fat leads to stimulation of endosymbiotic & colonic archaeal growth. Aryo-Dravidian Neanderthalic population has archaeal induced acquired porphyria which can lead to a human origin as well as resistance to emerging viruses like Covid 19. The porphyrion can form a template for further corona virus abiogenetic replication. The porphyrin Covid 19 complexes can produce protection of the human tissues from Covid 19 & prevent the emergence of infection & death. The emerging viruses and Covid 19 can be detected in the Aryo-Dravidian Neanderthalic & similar populations but they tend to be free of Covid 19 disease state leading to death. Heme like porphyrins & archaeal symbiosis can ameliorate the Covid 19 state
