Thanks for all the responses.


The issue for me is not whether Marx did or didnot dedicate any aspect of
his work to Darwin. Rather, I think Marx's concepts of competition and
growth are very much related to Darwinian notions of evolution and
natural selection. Moreover, I've always thought "reproduction" was
Marx's key methodological concept. 


Natural selection is a process that involves competitive rivalry and
adaptation to environmental change. The most "fit" organism evolve,
expand, and eventually dominant their competitive rivals.


Marx's theory of surplus value (his major theoretical result) explains
how capital is able to reproduce itself and which firms (and managerial
strategies, technologies) are most likely to survive over time. The
economic "fitness" of the firm (technology, managerial strategy) is
measured by its profitability. Capitals that generate the most surplus
value are able to evolve and expand at the expense of their rivals.


So, in my own thinking about topics that are beyond the material included
in <underline>Capital</underline> I've always started with the basic
biological metaphor, namely, what conditions are necessary and sufficient
for an organization, institution, or economic phenomena to reproduce
itself. There are a ton of economic and social issues that Marx never
addressed, hence finding a way to get at the core of Marx's methodology
is necessary and useful for attacking many of today's headline issues. 


Evolutionary game theory is an approach that was originally developed in
biology, but there are now many applications. And, it seems to me to be
an approach that is quite conformable with Marx's methodology. My hope
was that I'd be able to find a reference that directly connects Marx's
methodology to Darwin's methodology. 


Again, thanks for the references and the comments.
