Genetic Evidence for Geographic Structure within the Neanderthal Population
PSMC estimates of Neanderthal effective population size ( N e ) exhibit a roughly 5-fold decline across the most recent 20~ky before the death of each fossil. To explain this pattern, this article develops new theory relating genetic variation to geographic population structure and local extinction. It argues that the observed pattern results from subdivision and gene flow. If two haploid genomes are sampled from the same subpopulation, their rec…
Resources and Population Dynamics
This chapter describes the effects that the characteristics of individuals have on the dynamics and stability of populations. It shows that these effects are profound, and have important practical consequences. The chapter introduces the fundamental principles of population growth: the exponential increase of unregulated populations, various mechanisms that regulate population growth, and a method called "cobwebbing" that is useful for understand…
A Late Holocene Population Bottleneck in California Tule Elk (Cervus elaphus nannodes): Provisional Support from Ancient DNA
Brief communication: The Thule migration: Rejecting population histories using computer simulation
Locked within our genetic code are the histories of our genes and the genes of our ancestors. Deciphering a population's history from genetic data often involves lengthy investigations of many loci for many individuals. We test hypothetical population histories of the Thule expansion using a new coalescent simulation method that uses little more than mitochondrial haplogroup data. This new methodology rejects a severe bottleneck at expansion and …

On Equifinality in Faunal Analysis
A faunal assemblage may be dominated by dense bones either because the soft ones have been transported away or because they have been gnawed beyond recognition. Archaeologists have often despaired of distinguishing between these hypotheses and have attributed the problem to equifinality-to the fact that different causes can produce identical outcomes. Yet under the models of transport and attrition studied here, these causes do not produce identi…
Genetic traces of ancient demography
Patterns of gene differences among humans contain information about the demographic history of our species. Haploid loci like mitochondrial DNA and the nonrecombining part of the Y chromosome show a pattern indicating expansion from a population of only several thousand during the late middle or early upper Pleistocene. Nuclear short tandem repeat loci also show evidence of this expansion. Both mitochondrial DNA and the Y chromosome coalesce with…
Human nature: A critical reader
The phylogenetic approach to comparing human populations
Genetic admixture in the Late Pleistocene
The replacement hypothesis of modern human origins holds that the original population of modern humans expanded throughout the world, replacing existing archaic populations as it went. If this expanding population interbred with the peoples it replaced, then some archaic mitochondria might have been introduced into the early modern gene pool. Such mitochondria would be recognizable today because they should differ from other modern mitochondria a…
Estimating sexual dimorphism by method‐of‐moments
Estimating the degree of sexual dimorphism is difficult in fossil species because most specimens lack indicators of sex. We present a procedure that estimates sexual dimorphism in samples of unknown sex using method-of-moments. We assume that the distribution of a metric trait is composed of two underlying normal distributions, one for males and one for females. We use three moments around the mean of the combined-sex distribution to estimate the…

Three components of genetic drift in subdivided populations
Wright's metaphor of sampling is extended to consider three components of genetic drift: those occurring before, during, and after migration. To the extent that drift at each stage behaves like an independent random sample, the order of events does not matter. When sampling is not random, the order does matter, and the effect of population size is confounded with that of mobility. The widely cited result that genetic differentiation of local grou…
Statistical analysis of the migration component of genetic drift
Statistical methods are introduced for analysis of the migration component of genetic drift, i.e., of the stochastic changes that affect allele frequences during migration between local groups. Attention focuses on α M , a parameter that measures the extent to which this component of drift departs from the ideal of independent random sampling, and which can be interpreted as a measure of the extent to which migration is kin‐structured. It is show…
Does Biology Constrain Culture
Most social scientists would agree that the capacity for human culture was probably fashioned by natural selection, but they disagree about the implications of this supposition. Some believe that natural selection imposes important constraints on the ways in which culture can vary, while others believe that any such constraints must be negligible. This article employs a "thought experiment" to demonstrate that neither of these positions can be ju…
Human sociobiology
Sociobiology provides a perspective from which much of human behavior seems to make sense, and we expect that its importance will grow in years to come. We believe, however, that its current development is flawed by several widespread misunderstandings. Like other students of nature, sociobiologists are greatly interested in adaptation, particularly as embodied in W.D. Hamilton's theory of inclusive fitness. However, natural selection produces ad…

Data collection and information loss in the study of spatial pattern
In recording a spatial distribution some information is inevitably lost. In designing research it is important to ensure that techniques of data collection do not obscure those portions of the variation in spatial distributions which are of interest. This paper explores the relationships between data collection procedures and information loss. Formulae are presented which allow requirements concerning quadrat size or accuracy of measurement in po…

Correlations between relatives in small populations
Correlations between relatives in small, closed populations can be substantially smaller than predicted by the classical formulas of population genetics. This effect is especially pronounced for relatives whose most recent common ancestor is several generations removed. When the effective population size is small, correlations between even close relatives can be negative. This implies that in small populations conventional estimators of quantitat…
The Sociobiology of Sex and Sexes Today [and Comments and Reply]
Three problems pertaining to sex and sexes-why sex exists at all, why there should normally be two mating types in a sexual species, and why the two should so often be dimorphic (take the form of male and female)-have created a crisis in evolutionary theory. This paper contains a sketch of these puzzles and some opinions about the direction in which solutions are likely to be found, including a new theory of sex chromosome morphology and activity…
