Primates are characterized by relatively late ages at first reproduction, long lives and low
fertility. Together, these traits define a life-history of reduced reproductive effort …

Over recent millennia, human populations have regularly reconstructed their subsistence
niches, changing both how they obtain food and the conditions in which they live. For …

Interest in incorporating life history research from evolutionary biology into the human
sciences has grown rapidly in recent years. Two core features of this research have the …

This chapter focuses on (1) outlining an adaptationist perspective on physical
attractiveness,(2) presenting the basic questions that this perspective leads us to ask,(3) …

Across taxa, many life‐history traits vary as a function of differences in body size. 1–5 Among
primates, including humans, allometric relationships explain many trends in metabolic …

It is well established that early life environmental signals, including nutrition, set the stage for
long-term health and disease risk–effects that span multiple generations. This relationship …

Objectives: Previous research among foragers and theory suggests that nonmaternal
caregivers offer essential assistance, which supports female reproduction and the costs …

One of the defining features of human evolution is our demographic success. As of August
2019, the world's population exceeds 7.7 billion. The human capacity for population growth …

Teen motherhood is the prevalent childbearing pattern in most traditional populations. Yet
early motherhood is associated with negative biological and social outcomes in the …

Small populations are susceptible to high genetic loads and random fluctuations in birth and
death rates. While these selective forces can adversely affect their viability, small …
