  1. Diachronic lineage transitions within a society are more likely to move away from matriliny than toward matriliny (p. 11).Shenk, Mary K. - When does matriliny fail? The frequencies and causes of transitions to and f..., 2019 - 2 Variables

    Researchers looked at 180 of the 186 societies in the SCCS for changes over time in lineage systems. The goal was to estimate the frequency of transitions away from and to matriliny cross-culturally, as well as explore the potential causes of these patterns / transitions. The study focused on two overarching research questions: 1. How common are transitions away from matriliny and how often do ‘reverse transitions’ to matriliny occur? 2. What causes transitions to or from matriliny? Overall, the study found that transitions away from matriliny have been quite common within the time frames covered by the ethnographic samples available, while transitions from another system to matrility have been rare. In answering the second question, the researchers report the highest correlation is between subsistence transitions (towards pastoralism, intensive agriculture, or a market economy) and lineage transitions (away from matriliny) as well as between higher levels of social complexity (measured by stratification, slavery, and population size) and lineage transitions (away from matriliny).

  2. Transitions away from matriliny are positively associated with increased social complexity, markers of colonialism, and subsistence transitions towards pastoralism, intensive agriculture, or a market economy.Shenk, Mary K. - When does matriliny fail?

  3. Male reproductive skew (proxy measure being incidence of paternal half-siblings) will be highest in horticultural societies in comparison to other subsistence modes. (2)Ellsworth, Ryan M. - Comparative study of reproductive skew and pair-bond stability using genealo..., 2015 - 2 Variables

    Authors use genealogical data to investigate pair bond stability and reproductive skew across a sample of 80 small-scale societies. Results suggest that male reproductive skew and pair-bond stability are independent sources of cross-cultural variation in human mating patterns.
