That's almost redundant. I was just telling some friends earlier this story how before there were humans, there were these aliens that landed on earth not unlike cats. Then an omnipotent being materialized and told them that soon life would be evolving on this planet, and, in all likelihood, wipe them out. They had several choices -- one was to allow themselves to be dumbed down and treated as pets by this new species. Dumbing them down would prevent them from being perceived as a threat, and therefore allow them to survive. The cats said, "sure, that one".
