101 McElreath, RichardSocial learning and the maintenance of cultural variation: an evolutionary model and data from East AfricaHuman societies maintain between-group variation despite mixing of people and ideas. In order for variation to remain, migrants or their children must preferentially adopt local norms, customs, and beliefs. Yet the details of how cultural variation is maintained, despite mixing, remain unknown. This...Cultural variation; cultural identity; East Africa2004
102 Broughton, JohnTerminal Pleistocene fish remains from Homestead Cave, Utah, and implications for fish biogeography in the Bonneville BasinEleven fish species were identified from Homestead Cave, Utah. The remains, concentrated in the lowest stratum of the deposit, were accumulated by owls between approximately 11,200 and 10,100 14C yr B.P. and likely represent fish associated with the final die-off of the Lake Bonneville fauna. Fou...Fish assemblage; Quaternary; Lake Bonneville2000
103 O'Rourke, Dennis H.Ascertainment bias for non-twin relatives in twin proband studiesWhen 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; Models1982
104 Rogers, Alan R.; Jorde, Lynn B.Genetic evidence on modern human originsA 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 bottlenecks1995
105 Rogers, Alan R.; Jorde, Lynn B.Genetic structure of the Utah Mormons: comparison of results based on RFLPs, blood groups, migration matrices, isonymy, and pedigreesThe genetic structure of the Utah Mormon population is examined using 25 blood group and 47 RFLP alleles obtained from 442 subjects living in 8 geographic subdivisions. Nei's Gst was 0.013 (p < 0.002) for the RFLP data and 0.012 (p > 0.4) for the blood group data, showing that only 1% of the geneti...1994
106 Rogers, Alan R.; Jorde, Lynn B.Modeling the amplification dynamics of human Alu retrotransposonsRetrotransposons have had a considerable impact on the overall architecture of the human genome. Currently, there are three lineages of retrotransposons (Alu, L1, and SVA) that are believed to be actively replicating in humans. While estimates of their copy number, sequence diversity, and levels of ...Retrotransposons; Amplification dynamics; Mutation; Human-chimpanzee divergence2005
107 Broughton, JohnHomestead cave IchthyofaunaBiological evidence on the climatic and hydrographic history of the intermountain region would be much richer, if we had more than the present dribble of paleontological data on the fishes (Hubbs and Miller, 1948, p. 25). In this passage from their landmark synthesis of historical fish biogeograph...Homestead Cave; Ichthyofauna; Lake Bonneville2000
108 Rogers, Alan R.Pleistocene population X-plosion?In two recent papers, Kaessmann et al. presented DNA sequence data from the X chromosome (Xq13.3) of 30 chimpanzees and 69 humans (Kaessmann et al. 1999a; Kaessmann et al. 1999b). These data bear on two longstanding questions involving late Pleistocene demographic history: (1) whether the long-term...2000
109 Harpending, Henry C.; Rogers, Alan R.Detecting positive selection from genome scans of linkage disequilibriumThough a variety of linkage disequilibrium tests have recently been introduced to measure the signal of recent positive selection, the statistical properties of the various methods have not been directly compared. While most applications of these tests have suggested that positive selection has pl...Genome scans; Linkage disequilibrium; Gene trees2010
110 Rogers, Alan R.Population differences in quantitative characters as opposed to gene frequenciesHypotheses about evolution can be tested by comparing genetics differences with those of quantitative characters. Such comparisons are one source of information concerning the forces that maintain variation among natural populations.Genes; Evolution; Anthropology1986-05
111 Cashdan, Elizabeth A.How women competeMen are more physically aggressive and more risk-prone than women, but are not necessarily more competitive. New data show the gender difference in competitiveness to be one of kind rather than degree, with women and men competing in different ways and, to some extent, over different objectives, but...Gender differences, behavior; Competition; Aggression1999-06
112 Cashdan, Elizabeth A.Technological change and child behavior among the !KungHow does change in one part of a social system affect other parts? This is the central question that must be answered in order to understand the process through which culture changes. This paper is about a small piece of the problem. It investigates how changes in subsistence economy affect child be...Child behavior; Technological change; Foraging groups; Settled groups1988
113 Hawkes, KristenHuman life histories: primate trade-offs, grandmothering socioecology, and the fossil recordHuman life histories differ from those of other animals in several striking ways. Recently Smith and Tompkins (1995, p. 258) highlighted the combination of "slow" and "fast" features of human lives. Our period of juvenile dependency is unusually long, our age at first reproduction is late, and we h...Meat; Maturity; Life Span2003
114 McElreath, RichardWhen natural selection favors imitation of parentsIt is commonly assumed that parents are important sources of socially learned behavior and beliefs. However, the empirical evidence that parents are cultural models is ambiguous, and debates continue over their importance. A formal theory that examines the evolution of psychological tendencies to i...Transmission; Evolution; Culture2008
115 Hawkes, KristenHunting and the evolution of egalitarian societies: lessons from the HadzaPolitical hierarchies are common in human societies but absent among many mobile hunter-gatherers. So egalitarian social organizations have been attributed to limits that foraging imposes on wealth accumulation. But male-dominance hierarchies characterize all the great apes, our nearest relatives. ...2000
116 O'Rourke, Dennis H.Introduction: origins and settlement of the indigenous populations of the Aleutian ArchipelagoThe series of papers in this special issue of Human Biology use an interdisciplinary approach to address regional questions and to integrate disparate Aleutian data into a broad, synthetic effort. The contributors leverage decades of data on Aleut origins, biogeography, and behavior through integrat...2010
