The properties of the human Y chromosome–namely, male specificity, haploidy and escape
from crossing over—make it an unusual component of the genome, and have led to its …

Existing approaches within leadership studies often share a bias towards industrialized
societies and lack broader cross-cultural and ethological reference. Meanwhile, cross …

Dramatic events in human prehistory, such as the spread of agriculture to Europe from
Anatolia and the late Neolithic/Bronze Age migration from the Pontic-Caspian Steppe, can …

Background Comparisons of maternally-inherited mitochondrial DNA (mtDNA) and
paternally-inherited non-recombining Y chromosome (NRY) variation have provided …

The population of the Mediterranean island of Sardinia has made important contributions to
genome-wide association studies of complex disease traits and, based on ancient DNA …

Levels and patterns of genetic diversity can provide insights into a population's history. In
species with sex chromosomes, differences between genomic regions with unique …

Many complex human diseases are highly sexually dimorphic, suggesting a potential
contribution of the X chromosome to disease risk. However, the X chromosome has been …

Understanding the genetic architecture of disease is an enormous challenge, and should be
guided by evolutionary principles. Recent studies in evolutionary genetics show that sexual …

Studies have found a pronounced decline in male effective population sizes worldwide
around 3000–5000 years ago. This bottleneck was not observed for female effective …

Latin Americans arguably represent the largest recently admixed populations in the world.
This reflects a history of massive settlement by immigrants (mostly Europeans and Africans) …
