Past "mistakes" in human evolutionary chain?

Neither Nebraska man nor Piltdown man were accepted by the wider scientific community. In fact Piltdown man screwed the whole picture up.

Something that cannot be said for theists who keep bringing stuff like this up even though its dissimulation and distortion. look the real story up on Talkorigins.
