Thor Heyerdahl Proposed That Egyptians Could Have Navigated to the New

Thor Heyerdahl proposed that Egyptians could have navigated to the New World and influenced the emergence of civilization in the Americas. Erich von Däniken suggested that major human achievements had been borrowed from beings from outer space. What do these two views, both lacking credible scientific evidence, have in common?

A) Both suggest that evolutionary mechanisms explain both biological and cultural diversity across time and space.
B) Both reflect the popular media's negative effect on the quality of high school and college education.
C) Both take the position that major changes in ancient human lifestyles were the result of outside instruction or interference rather than the achievements of the natives of the places where the changes took place.
D) Both suggest that anthropology benefits from a broad range of views on human history, even if these views challenge the mainstream and even lack credible scientific evidence.
E) Both argue that historical events such as plant and animal domestication, the state, and city life were not brilliant discoveries, inventions, or secrets that humans needed to borrow but were, rather, long-term, gradual processes, developments with down-to-earth causes and effects.
