First, a food-distribution network of men’s hunting documented in 2001 and 2003 is analyzed considering evolutionary models of food sharing: kin selection, reciprocal altruism, generosity signaling, and costly signaling. The frequency of inter-household food transfers from 36 donor households to 102 recipient households are examined using matrix regression with independent variables representing embodied, material, and relational wealth. This analysis does not support the costly signaling model, but provides robust evidence for kinship, …
