Before the invention and popularization of the internet, a perfectly rational case was made to dismiss the veracity of arguments, based upon etymological evidence, that were being used by Professor Loren Eiseley in his efforts to prove that Charles Darwin had committed a research fraud by way of plagiarizing , among…
