The spread of modern humans across the globe has led to genetic adaptations to diverse
local environments. Recent developments in genomic technologies, statistical analyses, and …

Lactose intolerance refers to symptoms related to the consumption of lactose-containing
dairy foods, which are the most common source for this disaccharide. While four causes are …

Genetic predisposition to obesity presents a paradox: how do genetic variants with a
detrimental impact on human health persist through evolutionary time? Numerous …

Organisms can often adapt surprisingly quickly to evolutionary challenges, such as the
application of pesticides or antibiotics, suggesting an abundant supply of adaptive genetic …

Lactase persistence—the ability of adults to digest the lactose in milk—varies widely in
frequency across human populations. This trait represents an adaptation to the …

Researchers from diverse backgrounds are converging on the view that human evolution
has been shaped by gene–culture interactions. Theoretical biologists have used population …

There has long been interest in understanding the genetic basis of human adaptation. To
what extent are phenotypic differences among human populations driven by natural …

Members of the genus Brucella are pathogenic bacteria exceedingly well adapted to their
hosts. The bacterium is transmitted by direct contact within the same host species or …

Comparative studies of ethnically diverse human populations, particularly in Africa, are
important for reconstructing human evolutionary history and for understanding the genetic …

Evolutionary theory is one of the most wide-ranging and inspiring of scientific ideas. It offers
a battery of methods that can be used to interpret human behaviour. But the legitimacy of this …
