There have been numerous instances of fake evidence for evolution support. The fact that they are no longer accepted as evidence does not negate the fact that they existed.
And I was specific in my non-falsifiable contention. I mentioned Darwinism. Read on Dr James Shapiro.
But this is an important point...if evidence was fake, who revealed that it was fake? I mean, if they are no longer accepted as evidence, that means that someone proved that they were fake...but just because some pieces of evidence were fake, does that mean that the whole support for evolution is swept away? I doubt very much, that support for evolution hinges on just a few pieces of evidence...
