Little is known about brain aging or dementia in nonindustrialized environments that are similar to how humans lived throughout evolutionary history.
Social network analysis provides an important framework for studying the causes, consequences, and structure of social ties.
Ecologists routinely use statistical models to detect and explain interactions among ecological drivers, with a goal to evaluate whether an effect of interest changes in sign or magnitude in different contexts.
Chimpanzees (Pan troglodytes) possess a relatively generalized molar morphology allowing them to access a wide range of foods.
The selection pressures that drove dramatic encephalisation processes through the mammal lineage remain elusive, as does knowledge of brain structure reorganisation through this process.
Cousin marriage, a spousal union between close kin, occurs at high frequencies in many parts of the world.

Studies of cultural transmission—whether approached by archaeological or ethnographic means—have made great strides in identifying formal teaching and learning arrangements, which in turn can be closely aligned with models of social learning.
Compared to other species, the extent of human cooperation is unparalleled.
Remodelling is a fundamental biological process involved in the maintenance of bone physiology and function.
Intergroup and long-distance relationships are both central features of human social life, but because intergroup relationships are emphasized in the literature, long-distance relationships are often overlooked.
We considered a series of conservation-related research projects on the island of Pemba, Tanzania, to reflect on the broad significance of Beier et al.’s recommendations for linking conservation science with practical conservation outcomes.
The life histories of organisms are expressed as rates of development, reproduction, and survival.
Behavioral researchers increasingly recognize the need for more diverse samples that capture the breadth of human experience.
Nursing mothers face an energetic trade-off between infant care and work.
Life in social groups, while potentially providing social benefits, inevitably leads to conflict among group members.
Great-tailed Grackles (Quiscalus mexicanus) are a social, polygamous bird species whose populations have rapidly expanded their geographic range across North America over the past century.
Lower ambient temperature (Ta) requires greater energy expenditure to sustain body temperature.
This paper offers a systematic approach to quantifying the socio-economic role of forests for 'forest-dependent' communities.
Prior experiments with children across seven different societies have indicated U‑shaped age patterns in the likelihood of copying majority demonstrations.
