Global warming leads to endosymbiotic archaeal growth. The neoneanderthalic archaeaons have got magnetite capable of magnetoperception and quantal perception. The quantal perception of low level of EMF leads to frontal atrophy and cerebellar dominance producing a new neuronal phenotype with features of endemic cerebellar cognitive affective disorder. This forms a new autistic behavioural phenotype which is introverted, non-compassionate, non-empathic, psychopathic and with extrasensory perceptual abilities of telepathy, telekinesis and time travel leading to communication with other galactic civilizations. The neoneanderthalic archaeaons are capable of quantal perception and can communicate quantally with other star systems and multiverses. This leads on to the evolution of a galactic civilization. The neoneanderthalic archaeaons produce a metabolic phenotype capable of surviving in extremophilic environments of other star systems and can survive as civilization in other stars and exoplanets. The neoneanderthalic autistic phenotype with its extremophilic archaeaon organelle is suited for space colonisation. This constitutes a new homo galacticus species surviving other star systems.
