¿What do you think about? ¿Or what do you kwow about? May be at some level gives new arguments against “social-darwinism” beyond those of Pannehoek. For example, thats of Lynn Margulis, you have here:
‘Theory of symbiotic relationships driving evolution
She later formulated a theory to explain how symbiotic relationships between organisms of often different phyla or kingdoms are the driving force of evolution. Genetic variation is proposed to occur mainly as a result of transfer of nuclear information between bacterial cells or viruses and eukaryotic cells. While her organelle genesis ideas are widely accepted, symbiotic relationships as a current method of introducing genetic variation is something of a fringe idea.
She did however, hold a negative view of certain interpretations of Neo-Darwinism, excessively focused on inter-organismic competition, as she believed that history will ultimately judge them as comprising “a minor twentieth-century religious sect within the sprawling religious persuasion of Anglo-Saxon Biology.”[8] She also believed that proponents of the standard theory “wallow in their zoological, capitalistic, competitive, cost-benefit interpretation of Darwin – having mistaken him… Neo-Darwinism, which insists on [the slow accrual of mutations by gene-level natural selection], is in a complete funk.”[8]
She opposed such competition-oriented views of evolution, stressing the importance of symbiotic or cooperative relationships between species.’
