When our human ancestors began to migrate from the African savannahs across the Alps
into Northern Europe and Asia between 200,000 and 60,000 years ago, they encountered a …

Understanding human genetic diversity in Africa is important for interpreting the evolution of
all humans, yet vast regions in Africa, such as Chad, remain genetically poorly investigated …

Anatomically modern humans first arose in Africa. They rapidly spread out across the world
with their earliest dispersers reaching as far as Australasia 40000–60 000 years before …

The history of human populations in Africa is complex and includes various demographic
events that influenced patterns of genetic variation across the continent. Through genetic …

Background: The genetic composition of human North African populations is an amalgam of
different ancestral components coming from the Middle East, Europe, south-Saharan Africa …

In this response to Frank's comments regarding our recently published article in
Demography (Guo et al. 2014), we also address the literature she cites to support her …

Despite broad consensus on Africa as the main place of origin for anatomically modern
humans, their dispersal pattern out of the continent continues to be intensely debated. In …

This paper commences with a survey of genetic markers thought to give protection from
malaria, in connection with the issue of differentiation between An and NAn populations in …

Southern African populations speaking languages that are often-but inaccurately-grouped
together under the label 'Khoisan'are an important focus of molecular genetic research, not …

Genetic diversity patterns in nuclear versus mitochondrial systems and in low versus high
mutation rate systems do not support the hypothesis of a recent African origin for all of …
