From Ol' Darwin to Karl:
Dear Sir:
I thank you for the honour which you have done me by sending me your great work on Capital; & I heartily wish that I was more worthy to receive it, by understanding more of the deep and important subject of political Economy. Though our studies have been so different, I believe that we both earnestly desire the extension of Knowledge, & that this is in the long run sure to add to the happiness of Mankind.
I remain, Dear Sir
Yours faithfully,
Charles Darwin

Karl on Darwin:
Although it is developed in the crude English style, this is a book which contains the basis of natural history for our views.

So what ? how many products of science you use daily are/ have been invented by communists, atheists, liberals or fascists ? Would you hold science itself accountable for their foibles and stop using them ?
Yeah, so? Haven't you ever seen a polite refusal before? What did Darwin say that has you all worked up? He graciously declined the "honor," and he also said, in effect, that he didn't know beans about economics.
Is that the extent of your "evidence" for a Darwin-Marx connection?
