A Very Extended Family: Kin Recognition and Human Affairs, Dr. Daniel Krupp

Kinship plays a fundamental role in our daily affairs, as it does in the affairs of many other critters. Yet, there is an embarrassing dearth of psychological research into the effects of kinship on human behaviour and decision-making.
Drawing from work on other organisms (animals, plants, amoebae, and bacteria), Dr. Krupp explains why kinship is special, how we come to recognize our kin—including those we have never met before—and how its effects extend far beyond common notions of “the family.”
