Advanced extraterrestrial civilizations manipulated extant species on Earth. Erich von Däniken postulates that these were created to survive hostile off-world conditions.

Perhaps the only plausible solution, if we accept that such creatures were real, is that they were the result of extraterrestrial genetic manipulation.
