New finds in the palaeoanthropological and genomic records have changed our view of the
origins of modern human ancestry. Here we review our current understanding of how the …

Many researchers assume that until 10–12,000 years ago, humans lived in small, mobile,
relatively egalitarian bands. This “nomadic-egalitarian model” suffuses the social sciences. It …

Why do humans, uniquely among animals, cooperate in large numbers to advance projects
for the common good? Contrary to the conventional wisdom in biology and economics, this …

The deep evolutionary history of African populations, since the emergence of modern
humans more than 300,000 years ago, has resulted in high genetic diversity and …

Understanding the forces that influence natural variation within and among populations has
been a major objective of evolutionary biologists for decades. Motivated by the growth in …

Africa is the source of all modern humans, but characterization of genetic variation and of
relationships among populations across the continent has been enigmatic. We studied 121 …

Long-range migrations and the resulting admixtures between populations have been
important forces sha** human genetic diversity. Most existing methods for detecting and …

Genetic and paleoanthropological evidence is in accord that today's human population is
the result of a great demic (demographic and geographic) expansion that began …

Detailed knowledge about the geographical pathways followed by propagules from their
source to the invading populations—referred to here as routes of invasion—provides …

Approximately 20 years ago, Avise and colleagues proposed the integration of
phylogenetics and population genetics for investigating the connection between micro-and …
