Although range expansions have occurred recurrently in the history of most species, their
genetic consequences have been little investigated. Theoretical studies show that range …

Well-resolved molecular gene trees illustrate the concept of descent with modification and
exhibit the opposing processes of drift and migration, both of which influence population …

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

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 …

We consider the distribution of pairwise sequence differences of mitochondrial DNA or of
other nonrecombining portions of the genome in a population that has been of constant size …

Mutational processes of simple sequence repeats (SSRs) in complex genomes are poorly
understood. We examined these processes by introducing a two-phase mutation model. In …

The origin and taxonomic status of domesticated cattle are controversial. Zebu and taurine
breeds are differentiated primarily by the presence or absence of a hump and have been …

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 …

The proposal that all mitochondrial DNA (mtDNA) types in contemporary humans stem from
a common ancestor present in an African population some 200,000 years ago has attracted …
