Global climate has fluctuated greatly during the past three million years, leading to the
recent major ice ages. An inescapable consequence for most living organisms is great …

An appreciation of the scale and frequency of climatic oscillations in the past few million
years is modifying our views on how evolution proceeds. Such major events caused …

Population size history is essential for studying human evolution. However, ancient
population size history during the Pleistocene is notoriously difficult to unravel. In this study …

One enduring question in evolutionary biology is the extent of archaic admixture in the
genomes of present-day populations. In this paper, we present a test for ancient admixture …

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

Proponents of the model known as the “human revolution” claim that modern human

In The Hadza, Frank Marlowe provides a quantitative ethnography of one of the last
remaining societies of hunter-gatherers in the world. The Hadza, who inhabit an area of East …

A number of statistical tests for detecting population growth are described. We compared the
statistical power of these tests with that of others available in the literature. The tests …

We use variation at a set of eight human Y chromosome microsatellite loci to investigate the
demographic history of the Y chromosome. Instead of assuming a population of constant …

Distributions of pairwise differences often called “mismatch distributions” have been
extensively used to estimate the demographic parameters of past population expansions …
