Barham 1996

Lawrence S. Barham & Peter L. Smart, An early date for the Middle Stone Age of central Zambia. Journal of Human Evolution 30 (1996), 287–290.

The combination of small points similar to those associated with the earlier MSA in Zimbabwe (Volman, 1984) with heavier tools and lanceolates resembling the Lupemban of Central Africa (Clark, 1970; Phillipson, 1976) suggests an early Late Pleistocene date for the Twin Rivers assemblage.

In the broader African context Twin Rivers joins a small group of sites with late Middle Pleistocene dates for the MSA.

It is urgent to understand the future of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) transmission. We used estimates of seasonality, immunity, and cross-immunity for human coronavirus OC43 (HCoV-OC43) and HCoV-HKU1 using time-series data from the United States to inform a model of SARS-CoV-2 transmission. We projected that recurrent wintertime outbreaks of SARS-CoV-2 will probably occur after the initial, most severe pandemic wave. Absent other interventions, a key metric for the success of social distancing is whether critical care capacities are exceeded. To avoid this, prolonged or intermittent social distancing may be necessary into 2022. Additional interventions, including expanded critical care capacity and an effective therapeutic, would improve the success of intermittent distancing and hasten the acquisition of herd immunity. Longitudinal serological studies are urgently needed to determine the extent and duration of immunity to SARS-CoV-2. Even in the event of apparent elimination, SARS-CoV-2 surveillance should be maintained because a resurgence in contagion could be possible as late as 2024.

The poor preservation of Palaeolithic sites rarely allows the recovery of wooden artefacts, which served as key tools in the arsenals of early hunters. Here, we report the discovery of a wooden throwing stick from the Middle Pleistocene open-air site of Schöningen that expands the range of Palaeolithic weaponry and establishes that late Lower Palaeolithic hominins in Northern Europe were highly effective hunters with a wide array of wooden weapons that are rarely preserved in the archaeological record.


Åkesson 2020

Christine M. Åkesson et al., 2,100 years of human adaptation to climate change in the High Andes. Nature Ecology & Evolution 4 (2020), 66–74.


Humid montane forests are challenging environments for human habitation. We used high-resolution fossil pollen, charcoal, diatom and sediment chemistry data from the iconic archaeological setting of Laguna de los Condores, Peru to reconstruct changing land uses and climates in a forested Andean valley. Forest clearance and maize cultivation were initiated during periods of drought, with periods of forest recovery occurring during wetter conditions. Between ad 800 and 1000 forest regrowth was evident, but this trend was reversed between ad 1000 and 1200 as drier conditions coincided with renewed land clearance, the establishment of a permanent village and the use of cliffs overlooking the lake as a burial site. By ad 1230 forests had regrown in the valley and maize cultivation was greatly reduced. An elevational transect investigating regional patterns showed a parallel, but earlier, history of reduced maize cultivation and forest regeneration at mid-elevation. However, a lowland site showed continuous maize agriculture until European conquest but very little subsequent change in forest cover. Divergent, climate-sensitive landscape histories do not support categorical assessments that forest regrowth and peak carbon sequestration coincided with European arrival.

Groucutt 2018

Huw S. Groucutt & Michael D. Petraglia et al., Homo sapiens in Arabia by 85,000 years ago. Nature Ecology & Evolution 2 (2018), 800–809.


Understanding the timing and character of the expansion of Homo sapiens out of Africa is critical for inferring the colonization and admixture processes that underpin global population history. It has been argued that dispersal out of Africa had an early phase, particularly  130–90 thousand years ago (ka), that reached only the East Mediterranean Levant, and a later phase,  60–50 ka, that extended across the diverse environments of Eurasia to Sahul. However, recent findings from East Asia and Sahul challenge this model. Here we show that H. sapiens was in the Arabian Peninsula before 85 ka. We describe the Al Wusta-1 (AW-1) intermediate phalanx from the site of Al Wusta in the Nefud desert, Saudi Arabia. AW-1 is the oldest directly dated fossil of our species outside Africa and the Levant. The palaeoenvironmental context of Al Wusta demonstrates that H. sapiens using Middle Palaeolithic stone tools dispersed into Arabia during a phase of increased precipitation driven by orbital forcing, in association with a primarily African fauna. A Bayesian model incorporating independent chronometric age estimates indicates a chronology for Al Wusta of  95–86 ka, which we correlate with a humid episode in the later part of Marine Isotope Stage 5 known from various regional records. Al Wusta shows that early dispersals were more spatially and temporally extensive than previously thought. Early H. sapiens dispersals out of Africa were not limited to winter rainfall-fed Levantine Mediterranean woodlands immediately adjacent to Africa, but extended deep into the semi-arid grasslands of Arabia, facilitated by periods of enhanced monsoonal rainfall.

The house mouse (Mus musculus) represents the extreme of globalization of invasive mammals. However, the timing and basis of its origin and early phases of dispersal remain poorly documented. to track its synanthropisation and subsequent invasive spread during the develoment of complex human societies, we analyzed 829 Mus specimens from 43 archaeological contexts in Southwestern Asia and Southeastern Europe, between 40,000 and 3,000 cal. BP, combining geometric morphometrics numerical taxonomy, ancient mitochondrial DnA and direct radiocarbon dating. We found that large late hunter-gatherer sedentary settlements in the Levant, c. 14,500 cal. BP, promoted the commensal behaviour of the house mouse, which probably led the commensal pathway to cat domestication. House mouse invasive spread was then fostered through the emergence of agriculture throughout the Near East 12,000 years ago. Stowaway transport of house mice to Cyprus can be inferred as early as

Dizygotic twinning, the simultaneous birth of siblings when multiple ova are released, is an evolutionary paradox. Twin-bearing mothers often have elevated fitness, but despite twinning being heritable, twin births occur only at low frequencies in human populations. We resolve this paradox by showing that twinning and non-twinning are not competing strategies; instead, dizygotic twinning is the outcome of an adaptive conditional ovulatory strategy of switching from single to double ovulation with increasing age. This conditional strategy, when coupled with the well-known decline in fertility as women age, maximizes reproductive success and explains the increase and subsequent decrease in the twinning rate with maternal age that is observed across human populations. We show that the most successful ovulatory strategy would be to always double ovulate as an insurance against early fetal loss, but to never bear twins. This finding supports the hypothesis that twinning is a by-product of selection for double ovulation rather than selection for twinning.

Key 2020

Felix M. Key et al., Emergence of human-adapted Salmonella enterica is linked to the Neolithization process. Nature Ecology & Evolution 4 (2020), 324–333.


It has been hypothesized that the Neolithic transition towards an agricultural and pastoralist economy facilitated the emergence of human-adapted pathogens. Here, we recovered eight Salmonella enterica subsp. enterica genomes from human skeletons of transitional foragers, pastoralists and agropastoralists in western Eurasia that were up to 6,500 yr old. Despite the high genetic diversity of S. enterica, all ancient bacterial genomes clustered in a single previously uncharacterized branch that contains S. enterica adapted to multiple mammalian species. All ancient bacterial genomes from prehistoric (agro-)pastoralists fall within a part of this branch that also includes the human-specific S. enterica Paratyphi C, illustrating the evolution of a human pathogen over a period of 5,000 yr. Bacterial genomic comparisons suggest that the earlier ancient strains were not host specific, differed in pathogenic potential and experienced convergent pseudogenization that accompanied their downstream host adaptation. These observations support the concept that the emergence of human-adapted S. enterica is linked to human cultural transformations.

Anne C. Stone, getting sick in the Neolithic. Nature Ecology & Evolution 4 (2020), 286–287.

Ancient Salmonella enterica genomes from humans beginning to adopt farming lifestyles reveal insight into how epidemiological pathways were affected by human cultural transitions.

While infant mortality is high in extant and historical hunter-gatherers, life expectancy after age 15 is relatively high7. As agriculture is adopted fully, the move to sedentism and increased population densities likely changed disease ecology with increases in parasitism and infectious disease linked to waste and unclean water, as well as increases in the risk of zoonotic jumps of pathogens from domesticates.

Tom W. N. Walker & Erik Verbruggen et al., A systemic overreaction to years versus decades of warming in a subarctic grassland ecosystem. Nature Ecology & Evolution 4 (2020), 101–108.


Temperature governs most biotic processes, yet we know little about how warming affects whole ecosystems. Here we examined the responses of 128 components of a subarctic grassland to either 5–8 or >50 years of soil warming. Warming of >50 years drove the ecosystem to a new steady state possessing a distinct biotic composition and reduced species richness, biomass and soil organic matter. However, the warmed state was preceded by an overreaction to warming, which was related to organism physiology and was evident after 5–8 years. Ignoring this overreaction yielded errors of >100 % for 83 variables when predicting their responses to a realistic warming scenario of 1 °C over 50 years, although some, including soil carbon content, remained stable after 5–8 years. This study challenges long-term ecosystem predictions made from short-term observations, and provides a framework for characterization of ecosystem responses to sustained climate change.

The stratigraphy at Bacho Kiro Cave, Bulgaria, spans the Middle to Upper Palaeolithic transition, including an Initial Upper Palaeolithic (IUP) assemblage argued to represent the earliest arrival of Upper Palaeolithic Homo sapiens in Europe. We applied the latest techniques in 14C dating to an extensive dataset of newly excavated animal and human bones to produce a robust, high-precision radiocarbon chronology for the site. At the base of the stratigraphy, the Middle Palaeolithic (MP) occupation dates to >51,000 yr bp. A chronological gap of over 3,000 years separates the MP occupation from the occupation of the cave by H. sapiens, which extends to 34,000 cal bp. The extensive IUP assemblage, now associated with directly dated H. sapiens fossils at this site, securely dates to 45,820–43,650 cal bp (95.4 % probability), probably beginning from 46,940 cal bp (95.4 % probability). The results provide chronological context for the early occupation of Europe by Upper Palaeolithic H. sapiens.

In wintertime, high concentrations of atmospheric fine particulate matter (PM2.5) are commonly observed in the metropolitan area of Santiago, Chile. Hourly peaks can be very strong, up to 10 times above average levels, but have barely been studied so far. Based on atmospheric composition measurements and chemistry-transport modeling (WRF-CHIMERE), the chemical signature of sporadic skyrocketing wintertime PM2.5 peaks is analyzed. This signature and the timing of such extreme events trace their origin back to massive barbecue cooking by Santiago’s inhabitants during international soccer games. The peaks end up evacuated outside Santiago after a few hours but trigger emergency plans for the next day. Decontamination plans in Santiago focus on decreasing emissions from traffic, industry, and residential heating. Thanks to the air quality network of Santiago, this study shows that cultural habits such as barbecue cooking also need to be taken into account. For short-term forecast and emergency management, cultural events such as soccer games seem a good proxy to prognose possible PM2.5 peak events. Not only can this result have an informative value for the Chilean authorities but also a similar methodology could be reproduced for other cases throughout the world in order to estimate the burden on air quality of cultural habits.

Baumgarten. Studies on the Texts of the Desert of Judah 23 (Leiden 1997), 275–336.

In our argument we have put forward the case for a distinction of at least two different patterns of dualistic thought in the Qumran library. Both are clearly different, in structure and terminology as well as in their respective origins. On the one hand there is a sapiential tradition of ethically interested, but subsequently ontologized and cosmologized dualism. Its most developed example is the instruction on the two spirits 1QS 3:13-4:26 where cosmic, ethical, and psychological levels of dualistic expression are woven together. On the other hand, there is a pattern of pure cosmic dualism, without ethical or even psychological aspects, which is characterized by the opposition of leading angelic powers and their respective hosts of spiritual and human beings as well as by a strong use of the light-darkness paradigm. The most prominent example of this pattern is the War Rule, but there is earlier attestation in a few other pre-Essene texts which equally point to an origin in priestly circles.

Homo sapiens remains, molecular data and a revised chronology for the Bulgarian site of Bacho Kiro document the earliest known presence of our species in Europe, representing an important jigsaw piece in the Middle-to-Upper Palaeolithic transition.

These modelled ranges of the newly obtained radiocarbon measurements agree with the molecular date ranges calculated by Hublin et al. on the human bones. Thus, these human remains from Bacho Kiro currently reflect the earliest direct evidence of our species in Europe. Aside from Bacho Kiro, the directly dated human remains from the site of Peºtera cu Oase (Romania) at ca. 41 cal ka bp represent the oldest known modern human presence in Europe.

Hublin 2020

Jean-Jacques Hublin et al., Initial Upper Palaeolithic Homo sapiens from Bacho Kiro Cave, Bulgaria. nature 581 (2020), 299–302.


The Middle to Upper Palaeolithic transition in Europe witnessed the replacement and partial absorption of local Neanderthal populations by Homo sapiens populations of African origin1. However, this process probably varied across regions and its details remain largely unknown. In particular, the duration of chronological overlap between the two groups is much debated, as are the implications of this overlap for the nature of the biological and cultural interactions between Neanderthals and H. sapiens. Here we report the discovery and direct dating of human remains found in association with Initial Upper Palaeolithic artefacts2, from excavations at Bacho Kiro Cave (Bulgaria). Morphological analysis of a tooth and mitochondrial DNA from several hominin bone fragments, identified through proteomic screening, assign these finds to H. sapiens and link the expansion of Initial Upper Palaeolithic technologies with the spread of H. sapiens into the mid-latitudes of Eurasia before 45 thousand years ago3. The excavations yielded a wealth of bone artefacts, including pendants manufactured from cave bear teeth that are reminiscent of those later produced by the last Neanderthals of western Europe4–6. These finds are consistent with models based on the arrival of multiple waves of H. sapiens into Europe coming into contact with declining Neanderthal populations7,8.

But if global temperatures reach key threshold, dying trees will release warming gases.

Other researchers see the findings as a wake-up call for action, noting the world has already warmed about 1°C above preindustrial levels. “Even though tropical forest sinks will weaken, conserving them is still better than not having them at all and turning them into carbon sources,” says Richard Betts, a climate modeler specializing in the global carbon cycle at the University of Exeter. “It is not too late,” he adds, “to avoid the most severe impacts.”

Pulliainen 2020

Jouni Pulliainen et al., Patterns and trends of Northern Hemisphere snow mass from 1980 to 2018. nature 581 (2020), 294–298.

Warming surface temperatures have driven a substantial reduction in the extent and duration of Northern Hemisphere snow cover1–3. These changes in snow cover affect Earth’s climate system via the surface energy budget, and influence freshwater resources across a large proportion of the Northern Hemisphere4–6. In contrast to snow extent, reliable quantitative knowledge on seasonal snow mass and its trend is lacking7–9. Here we use the new GlobSnow 3.0 dataset to show that the 1980–2018 annual maximum snow mass in the Northern Hemisphere was, on average, 3,062 ± 35 billion tonnes (gigatonnes). Our quantification is for March (the month that most closely corresponds to peak snow mass), covers non-alpine regions above 40° N and, crucially, includes a bias correction based on in-field snow observations. We compare our GlobSnow 3.0 estimates with three independent estimates of snow mass, each with and without the bias correction. Across the four datasets, the bias correction decreased the range from 2,433–3,380 gigatonnes (mean 2,867) to 2,846–3,062 gigatonnes (mean 2,938)—a reduction in uncertainty from 33 % to 7.4 %. On the basis of our bias-corrected GlobSnow 3.0 estimates, we find different continental trends over the 39-year satellite record. For example, snow mass decreased by 46 gigatonnes per decade across North America but had a negligible trend across Eurasia; both continents exhibit high regional variability. Our results enable a better estimation of the role of seasonal snow mass in Earth’s energy, water and carbon budgets.

Martin J. P. Sullivan et al., Long-term thermal sensitivity of Earth’s tropical forests. science 368 (2020), 869–874.


The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (-9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our Results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate.


Wilkin 2020

Shevan Wilkin & Jessica Hendy et al., Dairy pastoralism sustained eastern Eurasian steppe populations for 5,000 years. Nature Ecology & Evolution 4 (2020), 346–355.


Dairy pastoralism is integral to contemporary and past lifeways on the eastern Eurasian steppe, facilitating survival in agriculturally challenging environments. While previous research has indicated that ruminant dairy pastoralism was practiced in the region by circa 1300 bc, the origin, extent and diversity of this custom remain poorly understood. Here, we analyse ancient proteins from human dental calculus recovered from geographically diverse locations across Mongolia and spanning 5,000 years. We present the earliest evidence for 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. We argue that ruminant dairying contributed to the demographic success of Bronze Age Mongolian populations and that the origins of traditional horse dairy products in eastern Eurasia are closely tied to the regional emergence of mounted herding societies during the late second millennium bc.

Yimin Yang, Dairying transformed Mongolia. Nature Ecology & Evolution 4 (2020), 288–289.

Proteomic analysis of human dental calculus finds evidence that ruminant dairying was accompanied with eastward human migration into Central Mongolia about 5,000 years ago and horse milk consumption was a part of the economic transformation in Mongolia around 1200 bc.

Wilkin and colleagues provide new clues for the timing and pathways of spread of domestic cattle and sheep from their origins in the Middle East into China. In the late fourth millennium bc, the earliest domestic cattle in China appear in the GanQing area9 and northeast China10, and the earliest domestic sheep are also found in the Gan-Qing area11. The detection of milk residue confirms the herding of cattle and sheep around 5,000 years ago in Mongolia5, yet herding was absent at that time in Xinjiang, northwestern China, the region connecting the Gan-Qing area and Central Asia; this suggests that Mongolia could have been the gateway into China for the eastward spread of cattle and sheep (Fig. 1). Recently, millet cultivation in southeastern Kazakhstan could be traced back to  2700 bc12, far from the domestication centres in northern China. But there is also no report of contemporary millet cultivation in Xinjiang; thus, the westward spread of millet might mirror the eastward spread of cattle and sheep, implicating the eastern Eurasian steppe as a potential crossroads for crops and livestock. The human carriers of cattle, sheep and millet, and the detailed pathways they followed will need to be clarified by multi-disciplinary research in the future.

Ingela Alger, Paul L. Hooper, Donald Cox, Jonathan Stieglitz & Hillard S. Kaplan, Paternal provisioning results from ecological change. PNAS 117 (2020), 10746–10754.


Paternal provisioning among humans is puzzling because it is rare among primates and absent in nonhuman apes and because emergent provisioning would have been subject to paternity theft. A provisioning “dad” loses fitness at the hands of nonprovisioning, mate-seeking “cads.” Recent models require exacting interplay between male provisioning and female choice to overcome this social dilemma. We instead posit that ecological change favored widespread improvements in male provisioning incentives, and we show theoretically how social obstacles to male provisioning can be overcome. Greater availability of energetically rich, difficult-to-acquire foods enhances female–male and male–male complementarities, thus altering the fitness of dads versus cads. We identify a tipping point where gains from provisioning overcome costs from paternity uncertainty and the dad strategy becomes viable. Stable polymorphic states are possible, meaning that dads need not necessarily eliminate cads. Our simulations suggest that with sufficient complementarities, dads can emerge even in the face of high paternity uncertainty. Our theoretical focus on ecological change as a primary factor affecting the trade-off between male mating and parenting effort suggests different possibilities for using paleo-climatic, archaeological, and genomic evidence to establish the timing of and conditions associated with emergence of paternal provisioning in the hominin lineage.

Keywords: paternal care | fatherhood | human evolution | parental investment | cooperation

Significance: Paternal provisioning is ubiquitous in human subsistence societies and unique among apes. How could paternal provisioning have emerged from promiscuous or polygynous mating systems that characterize other apes? An anomalous provisioning male would encounter a social dilemma: Since this investment in prospective offspring can be expropriated by other males, this investment is unlikely to increase the provisioner’s fitness. We present an ecological theory of the evolution of human paternal investment. Ecological change favoring reliance on energetically rich, difficult-to-acquire resources increases payoffs to paternal provisioning due to female–male and/or male–male complementarities. Paternal provisioning becomes a viable reproductive strategy when complementarities are strong, even under high paternity uncertainty. This model illuminates additional paths for understanding the evolution of fatherhood.

This marked difference between the intensity of communication of Assyria with the northern lands, and its complete lack in Transjordan, cannot be regarded as accidental. The “Great Game” of Neo-Assyrian times—complete with spies, assassinations, and fugitives—was played out in the north, and that is where Assyrian resources, communications, and administrative organization were at their most intense. In Sargonid times, when Egypt became the focus of trade and conquest, it was parts of southern Palestine that were subjected to more intense direct rule. Throughout, Transjordan remained loyal, so far as the sources indicate, and Ammon, Moab, and Edom were left as independent, tributary states with no direct imperial presence or involvement or attested exchanges of letters. Assyria did not need to interfere here: the Transjordanian states performed as required and Assyria was able to fulfill its objectives in this less strategic area at arm’s length. We are fortunate that Assyria’s lack of involvement in Trans-Jordan has been partially redressed in our day by Jim Sauer’s careful and pioneering archaeological research, and this paper is presented in his honor.

Sabine Gaudzinski-Windheuser, Elisabeth S. Noack, Eduard Pop & Wil Roebroeks et al., Evidence for close-range hunting by last interglacial Neanderthals. Nature Ecology & Evolution 2 (2018), 1087–1092.


Animal resources have been part of hominin diets since around 2.5 million years ago, with sharp-edged stone tools facilitating access to carcasses. How exactly hominins acquired animal prey and how hunting strategies varied through time and space is far from clear. The oldest possible hunting weapons known from the archaeological record are 300,000 to 400,000-year-old sharpened wooden staves. These may have been used as throwing and/or close-range thrusting spears, but actual data on how such objects were used are lacking, as unambiguous lesions caused by such weapon-like objects are unknown for most of human prehistory. Here, we report perforations observed on two fallow deer skeletons from Neumark-Nord, Germany, retrieved during excavations of 120,000-year-old lake shore deposits with abundant traces of Neanderthal presence. Detailed studies of the perforations, including micro-computed tomography imaging and ballistic experiments, demonstrate that they resulted from the close-range use of thrusting spears. Such confrontational ways of hunting require close cooperation between participants, and over time may have shaped important aspects of hominin biology and behaviour.
