Really?
1) The "Piltdown Man" was a hoax in which bone fragments were presented as the fossilised remains of a previously unknown early human. These fragments consisted of parts of a skull and jawbone, said to have been collected in 1912 from a gravel pit at Piltdown, East Sussex, England. The Latin name Eoanthropus dawsoni ("Dawson's dawn-man", after the collector Charles Dawson) was given to the specimen. The significance of the specimen remained the subject of controversy until it was exposed in 1953 as a forgery, consisting of the lower jawbone of an orangutan that had been deliberately combined with the skull of a fully developed modern human.
The Piltdown hoax is perhaps the most famous archeological hoax ever. It has been 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.

2) Professor Reiner Protsch von Zieten was a professor of anthropology at Frankfurt University for 30 years before he was forced to resign. It was found that he falsified dates on many "stone age" fossils which included a skull fragment named Hahnhöfersand Man which supposedly linked humans and Neanderthals. The scientific fraud only came to light when he was caught attempting to sell his department's complete chimpanzee skull collection to the United States. An investigation later established that he had also passed off fake fossils as genuine ones.

3) Since most people assume the fossil record is supportive of evolution...
Dr. David Kitts, professor of geology at the University of Oklahoma said, "Evolution requires intermediate forms between species and paleontology does not provide them...."
And Lord Zuckerman admitted there are no "fossil traces" of transformation from an ape-like creature to man! Even Stephen J. Gould of Harvard admitted, "The fossil record with its abrupt transitions offers no support for gradual change." Darwin admitted the same fact.
Famous fossil expert, Niles Eldredge confessed, "...geologists have found rock layers of all divisions of the last 500 million years and no transitional forms were contained in them." Dr. Eldredge further said, "...no one has yet found any evidence of such transitional creatures."
Concerning transitional fossils, world famous paleontologist Colin Patterson admitted that "there is not one such fossil for which one could make a watertight argument." Not one.
[CONCERNING THIS LAST POINT.... If there was a WATERTIGHT argument... we would ALL know about it!]
In recent years we have discovered that Neanderthal Man was simply a man with rickets and arthritis, not the much desired "ape man."

There is a LOT more that could be brought to the table - but bottom line - if the rational and scientific approach was working - these frauds would have been thrown out of their respective fields YEARS ago through peer-review. Instead much is simply accepted and moved into established "dogma"
