Grounding arguments about burials

Abstract: L'auteur commente plusieurs points de la contribution d'E. Lohof sur les relations entre pratiques funeraires et evolution sociale dans les societes du nord-est des Pays-Bas au Neolithique recent et a l'Age du Bronze ancien et moyen (Archaeological Dialogues, Vol. 1, N°2, pp. 98-118, 1994) : 1° interpretation de l'evolution des donnees funeraires en terme de demographie et de modeles d'echange et de subsistance ; 2° documentation descriptive des modeles presentes ; 3° arguments concernant l'emergence d'une representation de l'identite feminine dans les rites funeraires du Bronze moyen B

The Cultural Evolution of Neolithic Europe. EUROEVOL Dataset

Abstract: This dataset comprises the primary data collected for the Cultural Evolution of Neolithic Europe project (EUROEVOL), led by Professor Stephen Shennan, UCL. The dataset offers the largest repository of archaeological site and radiocarbon data from Neolithic Europe (4,757 sites and 14,131 radiocarbon samples), dating between the late Mesolithic and Early Bronze Age, as well as the largest collections of archaeobotanical data (>8300 records for 729 different species, genera and families, and the largest collection of animal bone data with >3 million NISP counts and >36,000 biometrics.

The Neolithic transition and European population history - a response

Abstract: We thank Crombe and Van Strydonck for their comments on our earlier paper (Gkiasta et al. 2003). They kindly draw attention to recent surveys of radiocarbon data from Belgium, most of which were published subsequent to our own work, which was carried out in 1999. Even at the time we were under no illusion that our compilation was complete: “It became clear in the course of the project that, despite the large sums of money which have been spent over the years on radiocarbon dating in Europe, the state of public availability of the dates, their context and associations and details which enable users to judge the reliability of dates is in general very poor. Thus, no claim is made that the database is in any sense complete” (Gkiasta et al. 2003: 48). It would probably also be as well to correct the impression that the dates we used were mainly derived from Gob (1990). Over half those finally included were extracted from the University of Lyon Banadora database; the remainder came from a wide range of other sources. The new dates from Belgium may well shed new light on the chronology of the transition in that region. New discoveries frequently do cause old interpretations to be modified or revised; we look forward to their analysis and demonstration of the implications of the new data to which they refer.

Phylogenetics and the evolution of cultural diversity

Abstract: Product description: This volume grew out of the first Society for American Archaeology’s President’s Invited Forum on Important Topics in American Archaeology. The various issues addressed in the chapters point out the complex nature of cultural transmission

The Web of Human Sexual Contacts

Abstract: Many ``real-world'' networks are clearly defined while most ``social'' networks are to some extent subjective. Indeed, the accuracy of empirically-determined social networks is a question of some concern because individuals may have distinct perceptions of what constitutes a social link. One unambiguous type of connection is sexual contact. Here we analyze data on the sexual behavior of a random sample of individuals, and find that the cumulative distributions of the number of sexual partners during the twelve months prior to the survey decays as a power law with similar exponents $\alpha \approx 2.4$ for females and males. The scale-free nature of the web of human sexual contacts suggests that strategic interventions aimed at preventing the spread of sexually-transmitted diseases may be the most efficient approach.

Massive migration from the steppe was a source for Indo-European languages in Europe

Abstract: We generated genome-wide data from 69 Europeans who lived between 8,000-3,000 years ago by enriching ancient DNA libraries for a target set of almost 400,000 polymorphisms. Enrichment of these positions decreases the sequencing required for genome-wide ancient DNA analysis by a median of around 250-fold, allowing us to study an order of magnitude more individuals than previous studies and to obtain new insights about the past. We show that the populations of Western and Far Eastern Europe followed opposite trajectories between 8,000-5,000 years ago. At the beginning of the Neolithic period in Europe, ∼8,000-7,000 years ago, closely related groups of early farmers appeared in Germany, Hungary and Spain, different from indigenous hunter-gatherers, whereas Russia was inhabited by a distinctive population of hunter-gatherers with high affinity to a ∼24,000-year-old Siberian. By ∼6,000-5,000 years ago, farmers throughout much of Europe had more hunter-gatherer ancestry than their predecessors, but in Russia, the Yamnaya steppe herders of this time were descended not only from the preceding eastern European hunter-gatherers, but also from a population of Near Eastern ancestry. Western and Eastern Europe came into contact ∼4,500 years ago, as the Late Neolithic Corded Ware people from Germany traced ∼75% of their ancestry to the Yamnaya, documenting a massive migration into the heartland of Europe from its eastern periphery. This steppe ancestry persisted in all sampled central Europeans until at least ∼3,000 years ago, and is ubiquitous in present-day Europeans. These results provide support for a steppe origin of at least some of the Indo-European languages of Europe.

A cross-cultural analysis of the behavior of women and men: implications for the origins of sex differences.

Abstract: This article evaluates theories of the origins of sex differences in human behavior. It reviews the cross-cultural evidence on the behavior of women and men in nonindustrial societies, especially the activities that contribute to the sex-typed division of labor and patriarchy. To explain the cross-cultural findings, the authors consider social constructionism, evolutionary psychology, and their own biosocial theory. Supporting the biosocial analysis, sex differences derive from the interaction between the physical specialization of the sexes, especially female reproductive capacity, and the economic and social structural aspects of societies. This biosocial approach treats the psychological attributes of women and men as emergent given the evolved characteristics of the sexes, their developmental experiences, and their situated activity in society.
