A theory of human life history evolution: Diet, intelligence, and longevity
TLDR
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. Expand
Evolutionary approach to below replacement fertility
TLDR
This model predicts that psychological mechanisms regulating parental investment in offspring quality may lead to greater and greater investment in own and offspring education, a smaller desired family size, a delay in the onset of reproduction, and a reduction in the total numbers of offspring produced.

In a study of social behavior of free-ranging vervet monkeys living along the Zambezi River near Livingstone, Zambia, 295 observations were made in which a juvenile female directed some type of matern
Paternal Care by Genetic Fathers and Stepfathers II: Reports by Xhosa High School Students
Abstract In this article we present a biosocial model of human male parental care that allows relationship (mating) effort to influence male parental allocations. The model recognizes four classes of… Expand
Does observed fertility maximize fitness among New Mexican men?
TLDR
An optimality model of human fertility is tested to determine whether current behavior does maximize fitness and, if not, to use the specific nature of the behavioral deviations from fitness maximization towards the development of models of evolved proximate mechanisms that may have maximized fitness in the past but lead to deviations under present conditions.

An Evolutionary and Ecological Analysis of Human Fertility, Mating Patterns, and Parental Investment
TLDR
A new ecological framework for understanding variations in each of those domains and then to apply the framework to understanding both the special characteristics of the authors' species in a comparative perspective and variations within and among human groups is introduced. Expand

Embodied Capital and the Evolutionary Economics of the Human Life Span
Paternal Care by Genetic Fathers and Stepfathers I: Reports from Albuquerque Men
Abstract We present a biosocial model of human male parental care that allows male parental allocations to be influenced not only by changes in the fitness (welfare) of the recipient offspring, but… Expand
