This paper uses data from eight past and present societies practicing intensive agriculture to measure the transmission of wealth across generations in preindustrial agricultural societies. Focusing on embodied, material, and relational forms of wealth, we compare levels of wealth between parents and children to estimate how effectively wealth is transmitted from one generation to the next and how inequality in one generation impacts inequality in the next generation. We find that material wealth is by far the most important, unequally distributed, and highly transmitted form of wealth in these societies, while embodied and relational forms of wealth show much weaker importance and transmission. We conclude that the unique characteristics of material wealth, and especially wealth in land, are key to the high and persistent levels of inequality seen in societies practicing intensive agriculture. We explore the implications of our findings for the evolution of inequality in the course of human history and s...

Human behavioral ecologists have shown that the reproductive lives of women are affected by both their husbands and the grandmothers of their children. Study of the combined effect of the roles of the husbands and mothers of 650 Khasi women aged 16–50 years supports the ideas that the reproductive agendas of husbands may require more than women want to invest and that mothers provide support and protective services to their daughters and grandchildren. In the absence of the woman’s mother, the husband’s agenda appears to have more influence on her reproductive career. In a cooperative vein, women's mothers may contribute to good marital choices. A view of reproductive pursuits that incorporates in‐laws enhances behavioral ecology approaches to the evolutionary comprehension of human reproductive behavior. This view also more readily interfaces with the cultural systems that set up the ecologies of reproductive life.
