Age- and sex-dependent sibling effects on early-life survival in preindustrial humans

2025-07-04

Abstract excerpt

<h4>ABSTRACT</h4> Siblings are an important part of an individual’s early-life environment and may therefore play an important role in shaping an individual’s fitness. The quantification of sibling effects is challenging, especially in long-lived species with extended parental care and overlapping generations, such as humans. Here we quantify how the survival status, age, and sex of older siblings shape childhood...
