▪ Abstract About 20 years ago, DNA sequences were separately described from the quagga
(a type of zebra) and an ancient Egyptian individual. What made these DNA sequences …

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

The past few years have witnessed a revolution in our ability to obtain DNA from ancient
humans. This important new data has added to our knowledge from archaeology and …

Neandertals, the closest evolutionary relatives of present-day humans, lived in large parts of
Europe and western Asia before disappearing 30,000 years ago. We present a draft …

Using DNA extracted from a finger bone found in Denisova Cave in southern Siberia, we
have sequenced the genome of an archaic hominin to about 1.9-fold coverage. This …

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 …

DNA that survives in museum specimens, bones and other tissues recovered by
archaeologists is invariably fragmented and chemically modified. The extent to which such …

Hybridization between humans and Neanderthals has resulted in a low level of Neanderthal
ancestry scattered across the genomes of many modern-day humans. After hybridization, on …

Comparisons of DNA sequences between Neandertals and present-day humans have
shown that Neandertals share more genetic variants with non-Africans than with Africans …

Genomic studies in African populations provide unique opportunities to understand disease
etiology, human diversity, and population history. In the largest study of its kind, comprising …
