Edenoites are descended from insects, not apes. Dex is not aware that humans did not evolve from bugs (as he discovered in an episode where he gives a report about how humans evolved from insects). Edenoites also possess telepathic abilities that are focused through a gem in the forehead, which can be hidden telepathically, though in times of stress can become visible. The gem is capable of focusing mental energy, as well as creating mental imagery that can be shared with others. Dex apparently possesses the knowledge needed to detoxify Leawood's rivers using solar-powered lasers.
