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 in… Expand
GENETIC EVIDENCE FOR A PLEISTOCENE POPULATION EXPLOSION

- 1 August 1995
It is inferred that a major expansion of the human population occurred during the late Pleistocene, because a simple model of population history that assumes that a population grows (or shrinks) suddenly from female size N0 toFemale size N1 is studied. Expand
Does Biology Constrain Culture
- A. Rogers
- 1 December 1988
A “thought experiment” is employed to demonstrate that neither side of the sociobiology debate is justified in dismissing the arguments of the other. Expand
The Genetic Structure of Ancient Human Populations
A new method of analyzing mtDNA sequences is used that is based on a theory of how mismatch distributions should preserve a record of population expansions and separations in the remote past. Expand
Genetic traces of ancient demography.

This genetic evidence denies any version of the multiregional model of modern human origins and implies instead that the authors' ancestors were effectively a separate species for most of the Pleistocene. Expand
Genetic Analysis of Lice Supports Direct Contact between Modern and Archaic Humans
It is shown that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years). Expand
Genetic perspectives on human origins and differentiation.
The issue of whether or not a population size bottleneck occurred among the authors' ancestors is under debate among geneticists as well as among anthropologists, and the Garden of Eden model of the origin of modern humans is confirmed. Expand
Genetic evidence on modern human origins.
Genetic evidence supports the "weak Garden of Eden" hypothesis, which holds that the human populations separated some 100,000 years ago but did not expand until tens of thousands of years later. Expand
Genetic variation among world populations: inferences from 100 Alu insertion polymorphisms.
Resampling analyses show that approximately 50 Alu polymorphisms are sufficient to obtain accurate and reliable genetic distance estimates, and demonstrate that markers with higher F(ST) values have greater resolving power and produce more consistent genetic distances estimates. Expand
Using mitochondrial and nuclear DNA markers to reconstruct human evolution

These findings support a recent African origin of modern humans, but this conclusion should be tempered by the possible effects of factors such as gene flow, population size differences, and natural selection. Expand
