Ache Life History: The Ecology and Demography of a Foraging People
This work uses this population of hunters and gatherers living in the neotropical rainforest of eastern Paraguay to make a signal contribution to human evolutionary ecology.
A theory of human life history evolution: Diet, intelligence, and longevity
A theory is proposed that unites and organizes observations and generates many theoretical and empirical predictions that can be tested in future research by comparative biologists, archeologists, paleontologists, biological anthropologists, demographers, geneticists, and cultural anthropologists.
“Economic man” in cross-cultural perspective: Behavioral experiments in 15 small-scale societies
A cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions found the canonical model – based on self-interest – fails in all of the societies studied.
Mortality rates among wild chimpanzees.
A synthetic life table for free-living chimpanzees, derived from data collected in five study populations, suggests the low mortality rate of human foragers relative to chimpanzees in the early adult years may partially explain why humans have evolved to senesce later than chimpanzees, and have a longer juvenile period.
Food Sharing Among Ache Foragers: Tests of Explanatory Hypotheses [and Comments and Reply]
This paper aims to describe and explain aspects of food sharing among Ache hunter-gatherers of eastern Paraguay. Food sharing has been widely held to be a fundamental feature of the hunting and
Growth rates and life histories in twenty‐two small‐scale societies
In sum, the origin and maintenance of different human ontogenies may require explanations invoking both environmental constraints and selective pressures.
LIFE HISTORY TRAITS IN HUMANS: Theory and Empirical Studies
▪ Abstract Life history theory offers evolutionary explanations for the timing of life events, with a particular focus on age-schedules of fertility and mortality and growth. Traditional models
Co-Residence Patterns in Hunter-Gatherer Societies Show Unique Human Social Structure
It is found that hunter-gatherers display a unique social structure where either sex may disperse or remain in their natal group, adult brothers and sisters often co-reside, and most individuals in residential groups are genetically unrelated, which suggests large social networks may help to explain why humans evolved capacities for social learning.
High adult mortality among Hiwi hunter-gatherers: implications for human evolution.
The high levels of conspecific violence and adult mortality in the Hiwi may better represent Paleolithic human demographics than do the lower, disease-based death rates reported in the most frequently cited forager studies.
why hunters gather: optimal foraging and the Aché of eastern Paraguay
The determinants of food choices made by hunter-gatherers have long been a topic of speculation and controversy. In this paper, we analyze the foraging behavior of the Ache of eastern Paraguay and
