## Executive GIST (TL;DR)
- The authors developed a mathematical framework linking an individual's **kinship network** to their life history, creating a dynamic nonlinear feedback between kin presence and vital rates. - They focused on kin effects from mothers, grandmothers and older sisters, positing those relatives influence child survival and so feed back on population-level fitness. - The team estimated kin-specific slope coefficients for child mortality using a Bayesian hierarchical model; the source reported no further methodological or numerical detail in the abstract. - A system of nonlinear equations was solved to couple kinship structure and survival, permitting explicit calculation of feedback between kin composition and child survival. - Using that coupled model, investigators computed stochastic sensitivities of both the **stochastic growth rate** and mean **lifetime reproductive output** to the kin-effect slope coefficients. - The authors hypothesised that negative associations of grandmothers, mothers, and older sisters (>10 years) with child mortality would be under positive selection because increasing their absolute values would raise population growth; they hypothesised the opposite for older sisters with positive associations with mortality. - The calculated sensitivities were consistent with the hypotheses reported: every estimated slope coefficient for kin presence on child mortality showed negative sensitivity to both fitness metrics in the authors' analysis. - The paper frames these results as a tool to study the coevolution of social behaviours and senescence in age-structured populations and notes the work is a preprint that has not been peer reviewed.

A focal individual's kinship network is a function of his/her life history, while that network in turn shapes the focal individual's life history through kin effects on reproduction, generating a dynamic, nonlinear feedback loop across the population. Assessing directional selection on kin effects, therefore, requires explicitly modelling the feedback between the kinship network and life history. Here, we develop such a framework and apply it to examine selection pressures on the cooperative behaviour of closely related kin, including mothers, grandmothers, and older sisters. We hypothesise that the negative association of grandmothers, mothers, and older sisters (>10 years) with child mortality are under positive selection because increasing the absolute values of these kin effects would increase the stochastic growth rate. Furthermore, we hypothesise that the positive association of older sisters with child mortality is subject to negative selection, as increasing this effect would reduce the stochastic growth rate. We estimate kin-specific slope coefficients for child mortality using a Bayesian hierarchical model and solve a system of nonlinear equations linking kinship structure and survival to account for the nonlinear feedback between kinship and child survival. Thereafter, we compute stochastic sensitivities of both the stochastic growth rate and the mean lifetime reproductive output to these slope coefficients. Consistent with our hypotheses, all slope coefficients for kin presence on child mortality are negatively sensitive to both fitness metrics. We discuss the applications of our framework to examine the coevolution of social behaviours and senescence in age-structured populations. ### Competing Interest Statement The authors have declared no competing interest.
