David Lewis-Williams is well-known in rock-art circles as the author of a series of articles drawing on ethnographic material and shamanism (notably connected with the San rock art of southern Africa) to gain new insights into the Palaeolithic cave art of western Europe. Some 15 years ago, with Thomas Dowson, he proposed that Palaeolithic art owed its inspiration at least in part to trance experiences (altered states of consciousness) associated with shamanistic practices. Since that article appeared, the shamanistic hypothesis has both been widely adopted and developed in the study of different rock-art traditions, and has become the subject of lively and sometimes heated controversy. In the present volume, Lewis-Williams takes the argument further, and combines the shamanistic hypothesis with an interpretation of the development of human consciousness. He thus enters another contentious area of archaeological debate, seeking to understand west European cave art in the context of (and as a marker of) the new intellectual capacities of anatomically modern humans. Radiocarbon dates for the earliest west European cave art now place it contemporary with the demise of the Neanderthals around 30,000 years ago, and cave art, along with carved or decorated portable items, appears to announce the arrival and denote the success of modern humans in this region. Lewis-Williams argues that such cave art would have been beyond the capabilities of Neanderthals, and that this kind of artistic ability is unique to anatomically modern humans. Furthermore, he concludes that the development of the new ability cannot have been the product of hundreds of thousands of years of gradual hominid evolution, but must have arisen much more abruptly, within the novel neurological structure of anatomically modern humans. The Mind in the Cave is thus the product of two hypotheses, both of them contentious — the shamanistic interpretation of west European Upper Palaeolithic cave art, and the cognitive separation of modern humans and Neanderthals. But is it as simple as that? Was cave art the hallmark of a new cognitive ability and social consciousness that were beyond the reach of previous hominids? And is shamanism an outgrowth of the hard-wired structure of the modern human brain? We begin this Review Feature with a brief summary by David Lewis-Williams of the book's principal arguments. There follows a series of comments addressing both the meaning of the west European cave art, and its wider relevance for the understanding of the Neanderthal/modern human transition.

Proteinaceous residues incorporated within the crystal structure of ostrich eggshells (OES) are retained without loss over geological time exceeding 10 million years. Degradation of the polypeptides, including hydrolysis to smaller peptide fragments and eventual release of free amino acids, decomposition, and racemization and epimerization occur at regular, predictable rates dependent on ambient temperature. The extent of isoleucine epimerization (alle/Ile ratio) in OES follows linear first-order reversible kinetics in controlled-temperature laboratory simulations of time up to an alle/Ile ratio in excess of 1.0. The hydrolysis of leucine also follows a predictable pattern, but deviates from first-order kinetics. A nonlinear mathematical model has been developed that adequately describes the pattern of leucine hydrolysis through a wide temperature range. Arrhenius parameters were derived from laboratory experiments combined with rate constant values found for 14 C-dated OES from stratified caves in southern Africa. These parameters for isoleucine epimerization and leucine hydrolysis differ by ca . 10%, allowing the simultaneous solution of the two equations for temperature, independent of sample age. Although the uncertainty of the simultaneous temperature is relatively high (± 10°C), it provides an effective means of identifying burned samples. If sample age is known, palaeotemperatures (the integrated thermal history experienced by an eggshell as opposed to an ‘instantaneous’ temperature) can be calculated with a precision of better than ± 1°C. The ages of levels at Border Cave, South Africa, from which anatomically modern human skeletal remains have been recovered, are dated by the extent of isoleucine epimerization in associated OES. The reaction is calibrated in the upper levels by a series of concordant radiocarbon dates on charcoal at 38 ka before present (BP). The amino acid dates on deeper levels indicate that the Howiesons Poort stratum at Border Cave is more than 70 ka old, and that anatomically modern humans occupied the site as early as 100 ka ago.

ABSTRACTBackgroundNearly all Eurasians have ∼2% Neanderthal ancestry due to several events of inbreeding between anatomically modern humans and archaic hominins. Previous studies characterizing the legacy of Neanderthal ancestry in modern Eurasians have identified examples of both adaptive and deleterious effects of admixture. However, we lack a comprehensive understanding of the genome-wide influence of Neanderthal introgression on modern human diseases and traits.ResultsWe integrate recent maps of Neanderthal ancestry with well-powered association studies for more than 400 diverse traits to estimate heritability enrichment patterns in regions of the human genome tolerant of Neanderthal ancestry and in introgressed Neanderthal variants themselves. First, we find that variants in regions tolerant of Neanderthal ancestry are depleted of heritability for all traits considered, except skin and hair-related traits. Second, the introgressed variants remaining in modern Europeans are depleted of heritability for most traits; however, we discover that they are enriched for heritability of several traits with potential relevance to human adaptation to non-African environments, including hair and skin traits, autoimmunity, chronotype, bone density, lung capacity, and menopause age. To better understand the phenotypic consequences of these enrichments, we adapt recent methods to test for consistent directional effects of introgressed alleles, and we find directionality for several traits. Finally, we use a direction-of-effect-aware approach to highlight novel candidate introgressed variants that influence risk for disease.ConclusionOur results demonstrate that genomic regions retaining Neanderthal ancestry are not only less functional at the molecular-level, but are also depleted for variation influencing a diverse array of complex traits in modern humans. In spite of this depletion, we identify traits where introgression has an outsized effect. Integrating our results, we propose a framework for using quantification of trait heritability and direction of effect in introgressed regions to understand how Neanderthals were different from modern humans, how selection acted on different traits, and how introgression may have facilitated adaptation to non-African environments.

AbstractResisting or tolerating microbes are alternative strategies to survive infection, but little is known about the evolutionary mechanisms controlling this balance. Here, genomic analyses of anatomically modern humans, extinct Denisovan hominins, and mice revealed a series of missense variants in the immune response inhibitor A20 (encoded by TNFAIP3), substituting non-catalytic residues of the ubiquitin protease domain to diminish IκB-dependent phosphorylation and activation of A20. Two A20 variants with partial phosphorylation deficits appeared beneficial: one originating in Denisovans and introgressed in modern humans throughout Oceania, and another in a mouse strain resistant to Coxsackievirus. By contrast, a variant with 95% loss of phosphorylation caused spontaneous inflammatory disease in humans and mice. Analysis of the partial phosphorylation variant in mice revealed diminished tolerance of bacterial lipopolysaccharide or to poxvirus inoculation as trade-offs for enhanced immunity.One Sentence SummaryModern and ancient variants reveal a genetically tunable element for balancing immunity and microbial tolerance.

The Levantine Aurignacian is a unique phenomenon in the local Upper Paleolithic sequence, showing greater similarity to the West European classic Aurignacian than to the local Levantine archaeological entities preceding and following it. Herewith we highlight another unique characteristic of this entity, namely, the presence of symbolic objects in the form of notched bones (mostly gazelle scapulae) from the Aurignacian levels of Hayonim Cave, Lower Galilee, Israel. Through both macroscopic and microscopic analyses of the items, we suggest that they are not mere cut marks but rather are intentional (decorative?) human-made markings. The significance of this evidence for symbolic behavior is discussed in its chrono-cultural and geographical contexts. Notched bones are among the oldest symbolic expressions of anatomically modern humans. However, unlike other Paleolithic sites where such findings were reported in single numbers, the number of these items recovered at Hayonim Cave is sufficient to assume they possibly served as an emblem of the Levantine Aurignacian.

Prompted by numerous endeavours to link a variety of brain illnesses/conditions with the introduction of palaeoart, especially rock art, the author reviews these proposals in the light of the causes of these psychiatric conditions. Several of these proposals are linked to the assumption that palaeoart was introduced through shamanism. It is demonstrated that there is no simplistic link between shamanism and brain disorders, although it is possible that some of the relevant susceptibility alleles might be involved in some shamanic experiences. Similarly, no connection between rock art and shamanism has been credibly demonstrated. Moreover, the time frame applied in all these hypotheses is fallacious for several reasons. These notions are all based on the belief that palaeoart was introduced by ‘anatomically modern humans’ and on the replacement hypothesis. Finally, the assumption that neuropathologies and shamanism preceded the advent of palaeoart is also suspect. These numerous speculations derive from neglect of the relevant empirical factors, be they archaeological or neurological.

Modern human dispersal into Europe is thought to have occurred with the start of the Upper Paleolithic around 50,000–40,000 y ago. The Levantine corridor hypothesis suggests that modern humans from Africa spread into Europe via the Levant. Ksâr ‘Akil (Lebanon), with its deeply stratified Initial (IUP) and Early (EUP) Upper Paleolithic sequence containing modern human remains, has played an important part in the debate. The latest chronology for the site, based on AMS radiocarbon dates of shell ornaments, suggests that the appearance of the Levantine IUP is later than the start of the first Upper Paleolithic in Europe, thus questioning the Levantine corridor hypothesis. Here we report a series of AMS radiocarbon dates on the marine gastropodPhorcus turbinatusassociated with modern human remains and IUP and EUP stone tools from Ksâr ‘Akil. Our results, supported by an evaluation of individual sample integrity, place the EUP layer containing the skeleton known as “Egbert” between 43,200 and 42,900 cal B.P. and the IUP-associated modern human maxilla known as “Ethelruda” before ∼45,900 cal B.P. This chronology is in line with those of other Levantine IUP and EUP sites and demonstrates that the presence of modern humans associated with Upper Paleolithic toolkits in the Levant predates all modern human fossils from Europe. The age of the IUP-associated Ethelruda fossil is significant for the spread of modern humans carrying the IUP into Europe and suggests a rapid initial colonization of Europe by our species.

We provide a comprehensive summary of data relating to the origin, chronology, and culture of the Denisovans— a separate hominin population, fi rst described in 2010 on the basis of aDNA extracted from fossils found in Denisova Cave, in the northwestern part of the Russian Altai. We cite the results of morphological and genomic studies of the teeth and postcranial bones of those hominins. On the basis of a large series of optical and radiocarbon dates of the Pleistocene strata of Denisova Cave, the timeline for the hominin evolution in that region is reconstructed. The chronology of the evolutionary events based on aDNA is discussed. We provide a detailed description of stone and bone tools, and ornaments made of various materials, from Denisova habitation horizons. It is demonstrated that the Paleolithic cultural sequence in that cave is the most complete in North and Central Asia, spanning the principal stages of human evolutionary history over the last 300 thousand years. Denisovan origins and their role in the emergence of anatomically modern humans are reconstructed on the basis of a large body of archaeological, skeletal, and genetic data relating to Africa and Eurasia. It is concluded that the Neanderthal and Denisovan genetic legacy in the modern human gene pool indicates the existence of several zones in Africa and Eurasia where H. erectus evolution proceeded independently. The same applies to the evolution of lithic technologies.

Recent anatomical analyses of a human maxilla found in 1927 in the Vestibule at Kent's Cavern, Devon, UK, have been interpreted as confirming its taxonomic status asHomo sapiens, while Bayesian modelling of dated fauna apparently ‘associated’ with it has been interpreted as suggesting a calendar age for the maxilla of around 44,200–41,500 years BP, rendering it the earliest fossil evidence for modern human presence in Northern Europe. In this paper, we examine fully the circumstances of the maxilla's discovery, data not previously considered. Based mostly on archival and limited published materials, as well as knowledge of the cave's stratigraphy, we provide a detailed examination of the context of the maxilla and associated finds. We urge caution over using a small selected sample of fauna from an old and poorly executed excavation in Kent's Cavern to provide a radiocarbon stratigraphy and age for a human fossil that cannot be dated directly, and we suggest that the recent dating should be rejected. We place our evaluation in the wider context of the dating of European early anatomically modern humans.

By 50,000 years ago, the effects of a ‘symbolic explosion’ — an efflorescence of human art, song, dance and ritual — were rippling across the globe. Applied to archaeological evidence, standard neo-Darwinian theory offers new understandings of this improbable event. The present article defines ‘symbolism’, models quasi-ritual behaviour in late archaic Homo sapiens, extends the argument to the emergence of anatomically modern humans and concludes with preliminary tests against archaeological, ethnographic and rock art data.

The study uses analyses of Mean Measure of Divergence (MMD) to assess the affinities of ten populations representing early anatomically modern humans, Upper Paleolithic Europeans, recent modern humans, and Neandertals. The 18-triat MMD analysis demonstrates that, dentally, Neandertals are quite divergent from all modern humans. The results of cluster analyses based on MMD values suggest two major clusters: Neandertals and modern humans. The data also suggest two sub-clusters within the modern human cluster. One links Upper Paleolithic Europeans with recent North Africans and Europeans. The other links early anatomically modern humans with Late Pleistocene Africans and recent Sub-Saharan Africans. These results do not support a close relationship between Neandertals and any modern human groups samples. They also tentatively suggest that, if the two populations were interbreeding, it is not reflected in their dental morphology. The results showing a close affinity between early anatomically modern humans and Sub-Saharan Africans are consist with the Recent African Origin model for modern human origins.
