A natural evolution for a settled human being seems to pass by the increase of brain capacity (therefore enlarging the skull), less powerful limbs (for the daily tasks would require less and less muscle effort, being the harder tasks executed by machines) and a pale, translucid skin (for the exposure to sunlight would be almost inexistent).
Could it be that ET sightings are but a vision of what nature has in mind for the evolution of a fully settled human being? A draft?
