The main point of that post is clearly correct, but I think the example of corporations is seriously flawed. It fails to appreciate the extent to which successful business practices consists of informal, non-systematic practical wisdom accumulated through long tradition and selected by success and failure in the market, not conscious a priori planning. The transfer of these practices is clearly very different from DNA-based biological inheritance, but it still operates in such ways that a quasi-Darwinian process can take place.

Applying similar analysis to modern science would be a fascinating project. In my opinion, a lot of the present problems with the proliferation of junk science stem not from intentional malice and fraud, but from a similar quasi-Darwinian process fueled by the fact that practices that best contribute to one's career success overlap only partly with those that produce valid science. (And as in the case of corporations, the transfer of these practices is very different from biological inheritance, but still permits quasi-Darwinian selection for effective practices.)
