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. Expand
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.

Genetic Variation and Population Structure in Native Americans
Evidence is observed of a higher level of diversity and lower level of population structure in western South America compared to eastern South America, a relative lack of differentiation between Mesoamerican and Andean populations, and a partial agreement on a local scale between genetic similarity and the linguistic classification of populations. Expand
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. Expand
Geographic Patterns of Genome Admixture in Latin American Mestizos
An analysis of admixture in thirteen Mestizo populations from seven countries in Latin America based on data for 678 autosomal and 29 X-chromosome microsatellites found extensive variation in Native American and European ancestry among populations and individuals and evidence that admixture across Latin America has often involved predominantly European men and both Native and African women.

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. Expand
Foraging decisions among Aché hunter-gatherers: New data and implications for optimal foraging models☆
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. Expand
Paternal effect on offspring survivorship among Ache and Hiwi hunter-gatherers: implications for modeling pair-bond stability.
The Northern Ache of Paraguay with approximately 600 individuals were settled as agricultural farmers in several reservations between 1971 and 1978. The Hiwi are hunter-gatherers of SouthwesternExpand
Y-chromosome evidence for differing ancient demographic histories in the Americas.
Age estimates based on Y-chromosome microsatellite diversity place the initial settlement of the American continent at approximately 14,000 years ago, in relative agreement with the age of well-established archaeological evidence. Expand
