African populations and the evolution of human mitochondrial DNA.
TLDR
The African origin hypothesis of human mtDNA evolution is supported by two statistical tests and two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans.
Grandmothering, menopause, and the evolution of human life histories.
TLDR
This hypothesis also accounts for the authors' late maturity, small size at weaning, and high fertility, and has implications for past human habitat choice and social organization and for ideas about the importance of extended learning and paternal provisioning in human evolution.
Showing off: Tests of an hypothesis about men's foraging goals
TLDR
A causal association between the wide sharing of game and the fact that men hunt and women do not is suggested and data show that men preferentially target resources in both hunting and gathering which are more widely shared, resources more likely to be consumed outside their own nuclear families.
Hadza Women's Time Allocation, Offspring Provisioning, and the Evolution of Long Postmenopausal Life Spans
Extended provisioning of offspring and long postmenopausal life spans are characteristic of all modern humans but no other primates. These traits may have evolved in tandem. Analysis of relationships…
Why Hunter-Gatherers Work: An Ancient Version of the Problem of Public Goods [and Comments and Reply]
People who hunt and gather for a living share some resources more widely than others. A favored hypothesis to explain the differential sharing is that giving up portions of large, unpredictable…
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…

  • 1 May 2003
TLDR
Using modern humans and chimpanzees to represent, respectively, genus Homo and australopithecines, two corollaries of the grandmother hypothesis are focused on: that ancestral age‐specific fertility declines persisted in the authors' genus, while 2) senescence in other aspects of physiological performance slowed down.
Grandmothering and the evolution of homo erectus.
TLDR
An alternative scenario is developed, that climate-driven adjustments in female foraging and food sharing practices, possibly involving tubers, favored significant changes in ancestral life history, morphology, and ecology leading to the appearance, spread and persistence of H. erectus.
Hunting and Nuclear Families: Some Lessons from the Hadza about Men's Work
Hadza hunter-gatherers display economic and social features usually assumed to indicate the dependence of wives and children on provisioning husbands and fathers. The wives and children of better…
Foraging decisions among Aché hunter-gatherers: New data and implications for optimal foraging models☆
TLDR
Energetic returns from various alternative resources and foraging strategies is probably the best single predictor of foraging patterns, and nutrient constraints should be added only when they significantly improve the predictive power of the model.
