Saying that Communism was founded partly on the evolutionary ideas of Charles Darwin is not only incorrect, it is in fact completely ludicrous. There is a simple proof for this. Look at the dates of the first publication of these two books:
 The Communist Manifesto 1848 |  On The Origin of Species 1859 |
Faced with such evidence, it's standard practice for the judge to now say 'case dismissed'. Communism predates Darwinism. End of story.
