Integrated data, including 100 human genomes from the Mesolithic, Neolithic and Early Bronze Age periods show that two major population turnovers occurred over just 1,000 years in Neolithic Denmark, resulting in dramatic changes in the genes, diet and physical appearance of the local people, as well as the landscape in which they lived.

An analysis involving the shotgun sequencing of more than 300 ancient genomes from Eurasia reveals a deep east–west genetic divide from the Black Sea to the Baltic, and provides insight into the distinct effects of the Neolithic transition on either side of this boundary.

For most ancient genomes, low sequencing depth restricts genotyping, limiting their study. Here, the authors test imputation performance of ancient human genomes by estimating error rates and potential bias introduced in downstream analyses.

An analysis of 101 ancient human genomes from the Bronze Age (3000–1000 bc) reveals large-scale population migrations in Eurasia consistent with the spread of Indo-European languages; individuals frequently had light skin pigmentation but were not lactose tolerant.

Analyses of 34 ancient genomes from northeastern Siberia, dating to between 31,000 and 600 years ago, reveal at least three major migration events in the late Pleistocene population history of the region.

Phylogenies reconstructed using 12 hepatitis B virus genomes, which were recovered from ancient human genome data, reveal a complex history of hepatitis B evolution that is not evident when using only modern samples.

Analyses of imputed ancient genomes and of samples from the UK Biobank indicate that ancient selection and migration were large contributors to the distribution of phenotypic diversity in present-day Europeans.

Analysis of two-million-year-old ancient environmental DNA from the Kap København Formation in North Greenland shows there was an open boreal forest with diverse plant and animal species, of which several taxa have not previously been detected at the site, representing an ecosystem that has no present-day analogue.

Ancient DNA analyses reveal that Viking Age migrations from Scandinavia resulted in differential influxes of ancestry to different parts of Europe, and the increased presence of non-local ancestry within Scandinavia.

Screening shotgun-sequencing data from ancient humans covering 37,000 years of Eurasian history uncovers the widespread presence of ancient bacterial, viral and parasite DNA and zoonotic pathogens coincide with the widespread domestication of livestock.

Kennewick Man, a 8,500-year-old male human skeleton discovered in Washington state, USA, has been the subject of scientific and legal controversy; here a DNA analysis shows that Kennewick Man is closer to modern Native Americans than to any other extant population worldwide.

A combined ancient genomic, metagenomic, and paleoproteomic analysis reveals lifestyle and dietary information of Upper Palaeolithic huntergatherers from San Teodoro cave in Sicily, Italy.

A complete pre-agricultural European human genome from a ∼7,000-year-old Mesolithic skeleton suggests the existence of a common genomic signature across western and central Eurasia from the Upper Paleolithic to the Mesolithic, and ancestral alleles in several skin pigmentation genes suggest that the light skin of modern Europeans was not yet ubiquitous in Mesolithic times.

Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region.

An analysis of 15 ancient genomes from individuals dating to AD 1670–1950 from Rapa Nui (also known as Easter Island) addresses questions about the population history of the island.

Population-scale ancient genomics are used to infer ancestry, social structure and pathogen infection in 108 Scandinavian Neolithic individuals from eight megalithic graves and a stone cist, showing that Neolithic plague was widespread.

Analysis of a large ancient genome dataset shows that genetic risk for multiple sclerosis rose in steppe pastoralists, providing insight into how genetic ancestry from the Neolithic and Bronze Age has shaped modern immune responses.

The first individual genome from the Clovis culture is presented; the origins and genetic legacy of the people who made Clovis tools have been under debate, and evidence here suggests that the individual is more closely related to all Native American populations than to any others, refuting the hypothesis that the Clovis people arrived via European (Solutrean) migration to the Americas.

Sequences of 137 ancient and 502 modern human genomes illuminate the population history of the Eurasian steppes after the Bronze Age and document the replacement of Indo-European speakers of West Eurasian ancestry by Turkic-speaking groups of East Asian ancestry.

Takashi Gakuhari, Shigeki Nakagome et al. report the genomic analysis on a 2.5 kya individual from the ancient Jomon culture in present-day Japan. Phylogenetic analysis with comparison to other Eurasian sequences suggests early migration patterns in Asia and provides insight into the genetic affinities between peoples of the region.

The enamel proteome from a 1.9-million-year-old Gigantopithecus tooth shows that the Gigantopithecus and Pongo (orangutan) lineages diverged 12–10 million years ago.

Birch pitch is thought to have been used in prehistoric times as hafting material or antiseptic and tooth imprints suggest that it was chewed. Here, the authors report a 5,700 year-old piece of chewed birch pitch from Denmark from which they successfully recovered a complete ancient human genome and oral microbiome DNA.

Genome-wide data from 400 individuals indicate that the initial spread of the Beaker archaeological complex between Iberia and central Europe was propelled by cultural diffusion, but that its spread into Britain involved a large-scale migration that permanently replaced about ninety per cent of the ancestry in the previously resident population.

It is generally accepted that Polynesian settlers were directly responsible for the extinction of New Zealand moa. Here, the authors present three series of radiocarbon ages that define the brief period of interaction between Polynesians and moa, and show that high human population densities are not a prerequisite for the extinction of megafauna populations.

Palaeoproteomic analysis of dental enamel from an Early Pleistocene Stephanorhinus resolves the phylogeny of Eurasian Rhinocerotidae, by enabling the reconstruction of molecular evolution beyond the limits of ancient DNA preservation.
