Hawkes, Kristen | Alyawara plant use and optimal foraging theory | Various authors have remarked on the importance of seeds in the pre-European diet of central Australian Aborigines. The Alyawara, an Arandic-speaking group, were typical in this respect. They collected edible seeds from nearly half the eighty-five plant species in their traditional subsistence inven... | Australia; Aborigines; Foraging; Seeds | 1981 |

McElreath, Richard | Are peasants risk-averse decision makers? | For decades, researchers studying small-scale, subsistence-oriented farmers have sought to explain why these "peasants" seem slow to acquire new technologies, novel agricultural practices, and new ideas from the larger societies that have engulfed them. The early work on this question suggested that... | Subsistance farmers; Risk-aversion; Risk-taking; Cultural conservatism; Cost-benefit analysis | 2002 |

O'Rourke, Dennis H. | Ascertainment bias for non-twin relatives in twin proband studies | When families are ascertained through affected twins, as for example when twin probands are selected from a registry and their non-twin relatives studied, a correction for ascertainment bias is needed. It is shown that probandwise counting (where relatives of doubly ascertained twin pairs are counte... | Genetic; Transmission; Models | 1982 |

Rogers, Alan R.; Jorde, Lynn B. | Ascertainment bias in estimates of average heterozygosity | Population geneticists work with a nonrandom sample of the human genome. Conventional practice ensures that unusually variable loci are most likely to be discovered and thus included in the sample of loci. Consequently, estimates of average heterozygosity are biased upward. In what follows we descri... | Bias (Epidemiology); Biometry; Heterozygote | 1996-05 |

Hawkes, Kristen | Assignment of relationship terms in Binumarien | Kinship systems have a perennial fascination. From Morgan's day to the present, a long succession of authors have produced their diagrams and algebraic explanations . . . Kinship terminology and its diagramatic arrangements provide, ready made, a delightful series of mathematical abstractions and it... | Binumarien; Binumariens | 1977 |

Hawkes, Kristen | Binumarien color categories | This paper has two aims. The first is to describe an ethnographically new system of color classification, Binumarien, a non-Austronesian or Papuan language of the Eastern Central Highlands of New Guinea2. In this connection we are particularly interested in relating our data to the Berlin and Kay (1... | Binumarien; Binumariens | 1975 |

McElreath, Richard | Can females gain additional paternal investment by mating with multiple males? a game theoretic approach | Although females may require only one mating to become inseminated, many female animals engage in costly mating with multiple males. One potential benefit of polyandrous mating is gaining parental investment from multiple males. We developed two game theoretic models to explore this possibility. Our... | Female multiple mating; Polyandry; Nonprocreative mating; Paternal investment; Mating benefits; Mating strategy | 2001-11 |

Cashdan, Elizabeth A. | Competition between foragers and food producers on the Botletli River, Botswana | The immigration of food-producing groups into areas occupied by hunters and gatherers must have been a common occurrence in prehistory. How were the hunter-gatherers affected by this? I describe here two groups of Kalahari Basarwa ('Bushmen'), one living along the flood plain of the lower Botletli ... | Kalahari Basarwa; Bushmen; Foraging; Cattle | 1986 |

Rogers, Alan R. | Doubts about isonymy | The method of isonymy, developed by Crow and Mange for estimating inbreeding from surname frequencies, requires an assumption that has not been appreciated: It is necessary to assume that all males in some ancestral generation, the founding stock, had unique surnames. Because this assumption is sel... | | 1991 |

McElreath, Richard | Economic man in cross-cultural perspective: behavioral experiments in 15 small-scale societies | Since "Selfishness examined . . ." (Caporael et al. 1989) appeared in these pages, more than 15 years ago, many additional experiments have strongly confirmed the doubts expressed by Caporael and her collaborators concerning the adequacy of self-interest as a behavioral foundation for the social sci... | Economic outcomes; Selfishness; Fairness; Reciprocity | 2005 |

McCullough, John M. | Evidence for assortative mating and selection in surnames: a case from Yucatan, Mexico | Surnames are often used as metaphors for genetic material on the assumption of neutrality and general immunity from systematic pressures. The Yucatec Maya use surnames of both Maya and Spanish origin. We find evidence of positive assortative mating by ethnic origin of surname and a slight bias away ... | Surnames; Assortative mating; Maya | 1985 |

Rogers, Alan R. | Evolution of time preference by natural selection | This paper entertains the hypothesis that human time preferences are in evolutionary equilibrium (i.e. that no mutation changing time preferences could be favored by natural selection). This hypothesis implies that the marginal rate of substitution (MRS) holding Darwinian fitness constant must equal... | Capitalism; Econometric models; Equilibrium | 1994-06 |

Rogers, Alan R. | Genetic evidence for a Pleistocene population explosion | Expansions of population size leave characteristic signatures in mitochondrial "mismatch distributions." Consequently, these distributions can inform us about the history of changes in population size. Here, I study a simple model of population history that assumes that, t generations before the pr... | | 1995 |

Rogers, Alan R.; Jorde, Lynn B. | Genetic evidence on modern human origins | A review of genetic evidence leads to the following conclusions concerning human population history: (1) Between 33,000 and 150,000 years ago the human population expanded from an initial size of perhaps 10,000 breeding individuals, reaching a size of at least 300,000. (2) Although the initial popu... | Population history; Mitochondrial DNA; Mismatch distribution; Intermatch distribution; Replacement hypothesis; Population bottlenecks | 1995 |
