I should add here that I am not against historical or social contingency - but the historical and social are always mediated by the biological and are also contain both immutable, difficult-to-change and highly contingent elements.

Also: the biological materially precedes the historical/social (unless you are an idealist) and mostly epistemically mediated by socio-historical forces. Basically, the material world science describes is usually censored by ideology/economy, or disrupts it as "the Real".
