in agreement with schneider, holland argued that an accurate account of biological theory and evidence supports the view that social bonds (and kinship) are indeed mediated by a shared social environment and processes of frequent interaction, care and nurture, rather than by genealogical relationships "per se" (even if genealogical relationships frequently correlate with such processes). in his 2012 book "social bonding and nurture kinship" holland argues that sociobiologists and later evolutionary psychologists misrepresent biological theory, mistakenly believing that inclusive fitness theory predicts that genetic relatedness "per se" is the condition that "mediates" social bonding and social cooperation in organisms. holland points out that the biological theory (see inclusive fitness) only specifies that a statistical relationship between social behaviors and genealogical relatedness is a criterion for the "evolution" of social behaviors. the theory's originator, w.d.hamilton considered that organisms' social behaviours were likely to be mediated by general conditions that typically "correlate" with genetic relatedness, but are not likely to be mediated by genetic relatedness "per se" (see human inclusive fitness and kin recognition). holland reviews fieldwork from social mammals and primates to show that social bonding and cooperation in these species is indeed mediated through processes of shared living context, familiarity and attachments, not by genetic relatedness "per se". holland thus argues that both the biological "theory" and the biological "evidence" is nondeterministic and nonreductive, and that biology as a theoretical and empirical endeavor (as opposed to 'biology' as a cultural-symbolic nexus as outlined in schneider's 1968 book) actually supports the "nurture kinship" perspective of cultural anthropologists working post-schneider (see above sections). holland argues that, whilst there is nonreductive compatibility around human kinship between anthropology, biology and psychology, for a full account of kinship in any "particular" human culture, ethnographic methods, including accounts of the people themselves, the analysis of historical contingencies, symbolic systems, economic and other cultural influences, remain centrally important.
