Combining radiocarbon dating with ethnohistory, the authors describe the timing and tempo of the spread of peaches in eastern North America after the fruit’s introduction. They show that peaches were cultivated and managed by Indigenous communities independently of influence from Spanish colonizers.

Genomic analyses of human populations in the Pacific provide insights into the peopling history of the region and reveal episodes of biological adaptation relating to the immune system and lipid metabolism through introgression from archaic hominins and polygenic adaptation.

Excavation in Island New Guinea reveals features associated with the Pacific Lapita cultural complex as well as sustained local cultural traditions from 3,480–3,060 years ago, contemporary with the earliest known Lapita settlements 700 km away. This supports New Guinea as a springboard for Lapita dispersal throughout the Pacific and illuminates their origins.

Warming temperatures and interactions between plants are the main drivers of changes in Arctic plant communities in response to climate change, and there is no evidence of overall biotic homogenization.

Genome-wide data of 16 ancient human individuals from islands of the North Moluccas, Sulawesi and East Nusa Tenggara reveal diverse sources of admixture and support a scenario of multiple dispersals into Wallacea.

The influence of climate on premodern civil conflict and societal instability is debated. Here, the authors combine archeological, historical, and paleoclimatic datasets to show that drought between 1400-1450 cal. CE escalated civil conflict at Mayapan, the largest Postclassic Maya capital of the Yucatán Peninsula.

Multi-proxy palaeoecological methods reconstruct phases of land clearance, maize cultivation and forest regrowth in the High Andes centuries before European incursion, and do not support the idea that forest regrowth and peak carbon sequestration were coincident with European arrival.

This paper proposes a research agenda towards the more just, equitable and effective integration of gender into blue carbon initiatives. It is a call-to-action towards closing the gender gap in the conservation and restoration of these ecosystems.

This study shows that conserving approximately half of global land area through protection or sustainable management could provide 90% of ten of nature’s contributions to people and could meet representation targets for 26,709 species of mammals, birds, amphibians, and reptiles. This finding supports recent commitments to conserve at least 30% of global lands and waters by 2030.

Shifts in species’ migration timing as a result of climate change can result in mismatched temporal overlap with their critical resources. Here the authors show that the magnitude and direction of shifts in juvenile Pacific salmon migration timing vary among species and populations, resulting in variable mismatch with marine productivity, which has implications for climate change vulnerability.

A standardized checklist of all known vascular plants shows the distribution of island native and endemic species, identifies their conservation status and highlights the need for actions to conserve them.

Liu et al. report genome-wide data of 33 ancient individuals from the Himalayas, illuminating the deep genetic history of Tibetans and other Tibeto-Burman-speaking populations around the Tibetan Plateau in fine resolution.

What is the state of trust in scientists around the world? To answer this question, the authors surveyed 71,922 respondents in 68 countries and found that trust in scientists is moderately high.

Little is known about the genetic landscape of people living in the Nile region prior to the Islamic migrations of the late 1st millennium CE. Here, the authors report genome-wide data for 66 ancient individuals to investigate the genetic ancestry of a Christian Period group from Kulubnarti.

Biological nitrogen fixation may impose stronger constraints on the carbon sink in natural terrestrial biomes and represent a larger source of agricultural nitrogen than is generally considered in analyses of the global nitrogen cycle.

Analysis of soundscape data from 139 globally distributed sites reveals that sounds of biological origin exhibit predictable rhythms depending on location and season, whereas sounds of anthropogenic origin are less predictable. Comparisons between paired urban–rural sites show that urban green spaces are noisier and dominated by sounds of technological origin.

Climate change assessment reports are increasing in complexity as the knowledge base grows exponentially. In this Perspective, the authors advocate, and provide recommendations, for knowledge synthesis to become more common as a way to better inform such assessments.

Bringing together multiple models and databases on nature’s contributions to people, the authors map these contributions globally and determine the critical areas where their magnitude is the highest and where they provide the highest potential human benefit.

Genome-wide ancestry profiles of four individuals, dating to 8,000 and 3,000 years before present, from the archaeological site of Shum Laka (Cameroon) shed light on the deep population history of sub-Saharan Africa.

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.

DNA analysis of 6 individuals from eastern and south-central Africa spanning the past approximately 18,000 years, and of 28 previously published ancient individuals, provides genetic evidence supporting hypotheses of increasing regionalization at the end of the Pleistocene.

Populations speaking Austronesian languages are numerous and widespread, but their history remains controversial. Here, the authors analyse genetic data from Southeast Asia and show that all populations harbour ancestry most closely related to aboriginal Taiwanese, while some also contain a component closest to Austro-Asiatic speakers.

Federated ML (FL) provides an alternative to train accurate and generalizable ML models, by only sharing numerical model updates. Here, the authors present the largest FL study to-date to generate an automatic tumor boundary detector for glioblastoma.

The recovery of human genomic data from environmental DNA samples raises ethical questions regarding consent, privacy, surveillance and data ownership, which will need to be grappled with as the environmental DNA field moves forward.

DNA analyses of Mesolithic and Neolithic individuals indicates the British Neolithic transition was mediated by incoming continental farmers, with little gene flow from local hunter-gatherers.

Spread of antimicrobial-resistant (AR) bacteria is a global concern, but contributing factors remain unclear. Here, authors analyze distribution of AR bacteria in households from three ethnic groups in Tanzania and find that livelihood factors are more strongly associated with AR prevalence than antibiotic use.

The Tyrolean Iceman is 5,300 years old and his mitochondrial genome has been previously sequenced. This study reports the full genome sequence of the Iceman and reveals that he probably had brown eyes, was at risk for coronary disease and may have been infected with the pathogen Lyme borreliosis.

Ancient proteins in human dental calculus from sites across Mongolia spanning 5,000 years suggest dairy consumption on the eastern Eurasian steppe by circa 3000 bc, and the later emergence of horse milking at circa 1200 bc, concurrent with the first evidence for horse riding.

The rate and extent of global biodiversity change is surpassing our ability to measure, monitor and forecast trends. We propose an interconnected worldwide system of observation networks — a global biodiversity observing system (GBiOS) — to coordinate monitoring worldwide and inform action to reach international biodiversity targets.

The past half century has seen a move from a multiregionalist view of human origins to widespread acceptance that modern humans emerged in Africa. Here the authors argue that a simple out-of-Africa model is also outdated, and that the current state of the evidence favours a structured African metapopulation model of human origins.

The cost of green electricity is unfairly distributed, with consumers paying more while industry actors are subsidized. Here, the authors find that reducing the inequity in cost burden by abolishing exemptions increases consumer acceptance of these costs.

Sweet corn is one of the most important vegetables in North America and has undergone different selection pressures than non-sweet cultivars. Here, the authors report its genome assembly and reveal the evolutionary history of modern sweet corn through population genomic analyses.

Formal criteria must be met to define a new human-driven epoch; the geological evidence appears to do so, with 1610 and 1964 both likely to satisfy the requirements for the start of the Anthropocene.

Type 2 diabetes (T2D) is prevalent in populations worldwide, however, mostly studied in European and mixed-ancestry populations. Here, the authors perform a genome-wide association study for T2D in over 5,000 sub-Saharan Africans and identify a locus, ZRANB3, that is specific for this population.
