> However, independently of the emergence of inclusive fitness theory, from 1960s onwards many anthropologists themselves had reexamined the balance of findings in their own ethnographic data and had begun to reject the notion that human kinship is 'caused by' blood ties (see Kinship). Anthropologists have gathered very extensive ethnographic data on human social patterns and behaviour over a century or more, from a wide spectrum of different cultural groups. The data demonstrates that many cultures do not consider 'blood ties' (in the genealogical sense) to underlie their close social relationships and kinship bonds. Instead social bonds are often considered to be based on location-based shared circumstances including living together (co-residence), sleeping close together, working together, sharing food (commensality) and other forms of shared life together. Comparative anthropologists have shown[6] that these aspects of shared circumstances are a significant component of what influences kinship in most human cultures, notwithstanding whether or not 'blood ties' are necessarily present (see Nurture kinship, below).
I like how easy you and p-e-w are making it to debunk your argument by citing a bunch of sources that don't support you. I think you're just racist conservatives making up facts from whole cloth to support some narrative of deintegration.
