I can't make any sense of this whole paragraph.
From fraud - The Great Piltdown Hoax - to a host of egregious practices and coverups
Such as? Piltdown doesn't qualify. It appears nearly certain (although the actual hoaxer is unknown to this day) that none of the scientists that published on or promoted Piltdown were involved in the hoax. They were victims of the hoax. Therefore there was no fraud involved. Furthermore there is no evidence that there was a "cover-up" at any time. That is no one (except of course the orginal hoaxer himself) knew of any problem with the fossils that they tried to conceal. When problems were discovered (by evolutionary anthropologists, btw) they were immediately and widely publicized.
Then read the post to which I am responding...as for Piltdown...lots of hoaxes so little time.
