Man, you just won't face it. Darwin rejected the dedication. Do you understand what rejection means? Read the website I recently linked.
Evolution (the best adapted survive to breed the next generation) is the opposite of "to each according to his needs." The two theories are incompatible.
I did read that website. It makes the association between the two even more clear, especially Marx's fondess for Darwin. Thanks for posting it!
Here. Let's grab the first portions.
Shall we chalk this association up to sheer coincidence?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

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