Proponents of the model known as the “human revolution” claim that modern human
behaviors arose suddenly, and nearly simultaneously, throughout the Old World ca. 40 …

Linkage disequilibrium (LD) plays a central role in current and proposed methods for
mapping complex disease genes. LD-based methods work best when there is a single …

Phylogeography is a discipline concerned with various relationships between gene
genealogies—phylogenetics—and geography. The word “phylogeography” was coined in …

Expansions of population size leave characteristic signatures in mitochondrial “mismatch
distributions.” Consequently, these distributions can inform us about the history of changes …

Abstract Analysis of variation in the hypervariable region of mitochondrial DNA (mtDNA) has
emerged as an important tool for studying human evolution and migration. However …

The “Weak Garden of Eden” model for the origin and dispersal of modern humans
(Harpendinget al., 1993) posits that modern humans spread into separate regions from a …

This study illustrates the potential of small-game data for identifying and dating Paleolithic
demographic pulses such as those associated with modern human origins and the later …

In recent years there has been a major growth of interest in exploring the analogies between
the genetic transmission of information from one generation to the next and the processes of …

Recent research has provided increasing support for the origins of anatomically and
genetically “modern” human populations in Africa between 150,000 and 200,000 years ago …

We report here a simulation study examining the effect of a recent spatial expansion on the
pattern of molecular diversity within a deme. We first simulate a range expansion in a virtual …
