Population growth makes waves in the distribution of pairwise genetic differences.
Episodes of population growth and decline leave characteristic signatures in the distribution of nucleotide (or restriction) site differences between pairs of individuals. These signatures appear inExpand

Signature of ancient population growth in a low-resolution mitochondrial DNA mismatch distribution.
A mismatch distribution is a tabulation of the number of pairwise differences among all DNA sequences in a sample. In a population that has been stationary for a long time these distributions fromExpand

The Osteological Paradox: Problems of Inferring Prehistoric Health from Skeletal Samples [and Comments and Reply]
Paleodemography and paleopathology presuppose that direct relationships exist between statistics calculated from archaeological skeletal series (e.g., skeletal lesion frequencies and mean age atExpand

Father Absence and Reproductive Strategy: An Evolutionary Perspective
Explanations offered by social scientists for the effects of father absence on children are reviewed; certain aspects of these interpretations are found wanting. Another explanation using theory fromExpand

The Genetic Structure of Ancient Human Populations
Ext. d'A.: In this paper we use a new method of analyzing mtDNA sequences that is based on a theory of how mismatch distributions -histograms of the number of pair-wise differences in the sample ofExpand

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 aExpand

Recent acceleration of human adaptive evolution
Genomic surveys in humans identify a large amount of recent positive selection. Using the 3.9-million HapMap SNP dataset, we found that selection has accelerated greatly during the last 40,000 years.Expand

Craniometric variation, genetic theory, and modern human origins.
Recent controversies surrounding models of modern human origins have focused on among-group variation, particularly the reconstruction of phylogenetic trees from mitochondrial DNA (mtDNA) and theExpand

Genetic perspectives on human origins and differentiation.
This is a review of genetic evidence about the ancient demography of the ancestors of our species and about the genesis of worldwide human diversity. The issue of whether or not a population sizeExpand

Why Hunter-Gatherers Work: An Ancient Version of the Problem of Public Goods [and Comments and Reply]
People who hunt and gather for a living share some resources more widely than others. A favored hypothesis to explain the differential sharing is that giving up portions of large, unpredictableExpand
