Fraudulent nonsense does not exist for very long in real science, and while it may be used by interested parties for their own aims (such as convincing the world that man originated in England of all places), the hoaxes are cut down very quickly and mentioned in passing.
This shows the differences between mainstream science and creation "science."
While nonsense does not last very long in real science, some of the most outlandish nonsense persists in creation "science" because it supports a religious position. As creation "science" is not based on evidence, if something supports one's position there is no compelling reason to discard it--it can't be falsified by the evidence, no matter how compelling!
That's why we see the same old worn out talking points used over and over by creationists. They are supported by belief and under the rules of creation "science" they can't be disproved by evidence.
And that's why they keep picking on Haeckel.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
