Ancient Aliens 11x10 - The Prototypes

Recent archaeological discoveries reveal a very differentpicture of what life on Earth looked like in the remote past.It was a real-life version of "Lord of the Rings," wherehumans shared the planet with various different types ofintelligent human-like species, such as Neanderthals,Denisovans, and even hobbits. But how is it that these varioushominid species developed separately in isolated pockets of theglobe? And why does no fossil evidence exist suggesting a slowgradual delineation from a common species? Ancient Astronauttheorists suggest these different intelligent species seem tohave come straight out of the incubator, and that Earth itselfmay have served as an extraterrestrial laboratory. A laboratorywhere different human prototypes once existed--but only onespecies was chosen to survive. Is mankind the result of anextraterrestrial experiment?
