How did Piltdown man get disputed then? It was taught in American schools for 40 years before it became not a fact.
Piltdown Man - Wikipedia the free encyclopedia
"The Piltdown hoax is perhaps the most famous paleoanthropological hoax ever to have been perpetrated. It is prominent for two reasons: the attention paid to the issue of human
evolution, and the length of time (more than 40 years) that elapsed from its discovery to its full exposure as a forgery."
"The Piltdown man hoax succeeded so well because, at the time of its discovery, the
scientific establishment believed that the large modern brain preceded the modern omnivorous diet, and the forgery provided exactly that evidence. It has also been thought that nationalism and cultural prejudice played a role in the less-than-critical acceptance of the fossil as genuine by some British scientists.
[7] It satisfied European expectations that the earliest humans would be found in
Eurasia, and the British, it has been claimed,
[7] also wanted a
first Briton to set against fossil hominids found elsewhere in Europe, including France and Germany."
This is why you dont call facts truths until you actually know the truth.
