Nell'opera di Antonio Pennacchi, il fascismo si configura come una questione d'identita, prima di tutto dal punto di vista territoriale, essendo l'autore originario di una delle citta di fondazione; ...in secondo luogo da un punto di vista biografico, considerata la sua lunga e articolata militanza politica, inaugurata con l'iscrizione al Msi; e infine da un punto di vista sociale, dato che Pennacchi, operaio in fabbrica per molti anni, non rinuncera mai a definire la bonifica delle Paludi Pontine come una riforma "di struttura marxista". La rappresentazione del fascismo si salda cosi alla creazione di un mito individuale, familiare e territoriale. Il Ventennio costituisce il contesto storico-sociale entro cui prende corpo l'epopea della famiglia Peruzzi, le cui vicende continueranno ad essere narrate fino all'epoca contemporanea (Canale Mussolini. Parte prima e Parte seconda; La strada del mare). Ma la rappresentazione del fascismo supera anacronisticamente i limiti della propria pertinenza storica per estendersi fino all'uomo di Neanderthal, prototipo di un'alternativa storico-antropologica indefettibilmente perduta (Le iene del Circeo; Camerata Neandertal) divenendo una questione sovrastorica e sovratemporale. Parole chiave: fascismo, Paludi Pontine, identita, Latina, Pennacchi, memoria, letteratura italiana contemporanea.

The Neanderthals populated western Europe from nearly 250,000 to 30,000 years ago when they disappeared from the archaeological record. In turn, populations of anatomically modern humans, Homo ...sapiens, came to dominate the area. Seeking to understand the nature of this replacement, which has become a hotly debated issue, Paul Mellars brings together an unprecedented amount of information on the behavior of Neanderthals. His comprehensive overview ranges from the evidence of tool manufacture and related patterns of lithic technology, through the issues of subsistence and settlement patterns, to the more controversial evidence for social organization, cognition, and intelligence. Mellars argues that previous attempts to characterize Neanderthal behavior as either "modern" or "ape-like" are both overstatements. We can better comprehend the replacement of Neanderthals, he maintains, by concentrating on the social and demographic structure of Neanderthal populations and on their specific adaptations to the harsh ecological conditions of the last glaciation.
Mellars's approach to these issues is grounded firmly in his archaeological evidence. He illustrates the implications of these findings by drawing from the methods of comparative socioecology, primate studies, and Pleistocene paleoecology. The book provides a detailed review of the climatic and environmental background to Neanderthal occupation in Europe, and of the currently topical issues of the behavioral and biological transition from Neanderthal to fully "modern" populations.

Neandertals and the Middle Paleolithic persisted in the Iberian Peninsula south of the Ebro drainage system for several millennia beyond their assimilation/replacement elsewhere in Europe. As only ...modern humans are associated with the later stages of the Aurignacian, the duration of this persistence pattern can be assessed via the dating of diagnostic occurrences of such stages. Using AMS radiocarbon and advanced pretreatment techniques, we dated a set of stratigraphically associated faunal samples from an Aurignacian III-IV context excavated at the Portuguese cave site of Pego do Diabo. Our results establish a secure terminus ante quem of ca.34,500 calendar years ago for the assimilation/replacement process in westernmost Eurasia. Combined with the chronology of the regional Late Mousterian and with less precise dating evidence for the Aurignacian II, they place the denouement of that process in the 37th millennium before present. These findings have implications for the understanding of the emergence of anatomical modernity in the Old World as a whole, support explanations of the archaic features of the Lagar Velho child's anatomy that invoke evolutionarily significant Neandertal/modern admixture at the time of contact, and counter suggestions that Neandertals could have survived in southwest Iberia until as late as the Last Glacial Maximum.
Neandertals are the best-studied of all extinct hominins, with a rich fossil record sampling hundreds of individuals, roughly dating from between 350,000 and 40,000 years ago. Their distinct fossil ...remains have been retrieved from Portugal in the west to the Altai area in central Asia in the east and from below the waters of the North Sea in the north to a series of caves in Israel in the south. Having thrived in Eurasia for more than 300,000 years, Neandertals vanished from the record around 40,000 years ago, when modern humans entered Europe. Modern humans are usually seen as superior in a wide range of domains, including weaponry and subsistence strategies, which would have led to the demise of Neandertals. This systematic review of the archaeological records of Neandertals and their modern human contemporaries finds no support for such interpretations, as the Neandertal archaeological record is not different enough to explain the demise in terms of inferiority in archaeologically visible domains. Instead, current genetic data suggest that complex processes of interbreeding and assimilation may have been responsible for the disappearance of the specific Neandertal morphology from the fossil record.
We present a high-quality genome sequence of a Neanderthal woman from Siberia. We show that her parents were related at the level of half-siblings and that mating among close relatives was common ...among her recent ancestors. We also sequenced the genome of a Neanderthal from the Caucasus to low coverage. An analysis of the relationships and population history of available archaic genomes and 25 present-day human genomes shows that several gene flow events occurred among Neanderthals, Denisovans and early modern humans, possibly including gene flow into Denisovans from an unknown archaic group. Thus, interbreeding, albeit of low magnitude, occurred among many hominin groups in the Late Pleistocene. In addition, the high-quality Neanderthal genome allows us to establish a definitive list of substitutions that became fixed in modern humans after their separation from the ancestors of Neanderthals and Denisovans.
The timing of Neanderthal disappearance and the extent to which they overlapped with the earliest incoming anatomically modern humans (AMHs) in Eurasia are key questions in palaeoanthropology. ...Determining the spatiotemporal relationship between the two populations is crucial if we are to understand the processes, timing and reasons leading to the disappearance of Neanderthals and the likelihood of cultural and genetic exchange. Serious technical challenges, however, have hindered reliable dating of the period, as the radiocarbon method reaches its limit at ∼50,000 years ago. Here we apply improved accelerator mass spectrometry (14)C techniques to construct robust chronologies from 40 key Mousterian and Neanderthal archaeological sites, ranging from Russia to Spain. Bayesian age modelling was used to generate probability distribution functions to determine the latest appearance date. We show that the Mousterian ended by 41,030-39,260 calibrated years bp (at 95.4% probability) across Europe. We also demonstrate that succeeding 'transitional' archaeological industries, one of which has been linked with Neanderthals (Châtelperronian), end at a similar time. Our data indicate that the disappearance of Neanderthals occurred at different times in different regions. Comparing the data with results obtained from the earliest dated AMH sites in Europe, associated with the Uluzzian technocomplex, allows us to quantify the temporal overlap between the two human groups. The results reveal a significant overlap of 2,600-5,400 years (at 95.4% probability). This has important implications for models seeking to explain the cultural, technological and biological elements involved in the replacement of Neanderthals by AMHs. A mosaic of populations in Europe during the Middle to Upper Palaeolithic transition suggests that there was ample time for the transmission of cultural and symbolic behaviours, as well as possible genetic exchanges, between the two groups.
Human genes governing innate immunity provide a valuable tool for the study of the selective pressure imposed by microorganisms on host genomes. A comprehensive, genome-wide study of how selective ...constraints and adaptations have driven the evolution of innate immunity genes is missing. Using full-genome sequence variation from the 1000 Genomes Project, we first show that innate immunity genes have globally evolved under stronger purifying selection than the remainder of protein-coding genes. We identify a gene set under the strongest selective constraints, mutations in which are likely to predispose individuals to life-threatening disease, as illustrated by STAT1 and TRAF3. We then evaluate the occurrence of local adaptation and detect 57 high-scoring signals of positive selection at innate immunity genes, variation in which has been associated with susceptibility to common infectious or autoimmune diseases. Furthermore, we show that most adaptations targeting coding variation have occurred in the last 6,000–13,000 years, the period at which populations shifted from hunting and gathering to farming. Finally, we show that innate immunity genes present higher Neandertal introgression than the remainder of the coding genome. Notably, among the genes presenting the highest Neandertal ancestry, we find the TLR6-TLR1-TLR10 cluster, which also contains functional adaptive variation in Europeans. This study identifies highly constrained genes that fulfill essential, non-redundant functions in host survival and reveals others that are more permissive to change—containing variation acquired from archaic hominins or adaptive variants in specific populations—improving our understanding of the relative biological importance of innate immunity pathways in natural conditions.
