Wow! That's quite the list! Nice job! The Piltdown fraud will no-doubt continue to cast a negative light on Darwinism for years to come.
I'll charitably assume that you are either being sarcastic, or that you didn't actually read the contents of the list.
The "Piltdown Man" was discovered BEFORE Darwin published. It was largely ignored in the early 1900's and by 1955 had been determined to be a fake using modern testing methods by SCIENTISTS! It is a positive light for scientists to uncover the fraud, not a negative. You are bearing false witness AGAIN!
Frauds are no fun fo anyone, but Piltown proves for all time that you cannot intuitively detect design, and cannot intuitively say anything about things found in isolation. Only by having a unifying theory of things happening through uniform process can we place artifacts in context and evaluate hypotheses.
Creationists and IDers have no reason at all to assert that Piltdown is a fraud. Even now they cannot claim it is a fraud unless they admit evolution is true and biologists have it right.
No one ever confessed to fraud, and a devout priest was present at one of the finds, so either Piltdown is a good find, or evolution is true, because only evolution gives a theoretical framework for asserting it is a phony.
