Comparison of simulated and proxy-based climate reconstructions for Mid-Holocene Europe reveals high uncertainty
Gridded and time-continuous paleoclimate model outputs are increasingly used to inform high-resolution models in biogeography and other disciplines. However, few studies quantitatively evaluate such outputs for bias, uncertainty, and consistency with other climate reconstructions of similar scale and scope of interest. Here we evaluate downscaled and bias-corrected output from two paleoclimate models against proxy-based reconstructions from Europ…
The Biad Standards
This article presents a series of recommendations for the publication of archaeological data, to improve their usability. These 12 recommendations were formulated by archaeological data experts who mined thousands of publications for different data types (including funerary practices, accelerator mass spectrometry dating, stable isotopes, zooarchaeology, archaeobotany and pathologies) during the initial construction of the Big Interdisciplinary A…
The Rise and Fall of BritainsDNA
Direct-to-consumer genetic ancestry testing is a new and growing industry that has gained widespread media coverage and public interest. Its scientific base is in the fields of population and evolutionary genetics and it has benefitted considerably from recent advances in rapid and cost-effective DNA typing technologies. There is a considerable body of scientific literature on the use of genetic data to make inferences about human population hist…
Reduced intensity of bone fat exploitation correlates with increased potential access to dairy fats in early Neolithic Europe
Modelling caprine age-at-death profiles using the Gamma distribution
Impact of modern cattle feeding practices on milk fatty acid stable carbon isotope compositions emphasise the need for caution in selecting reference animal tissues and products for archaeological inv…
Degraded animal fats, characterised by the presence of palmitic (C16:0) and stearic (C18:0) fatty acids and related glycerolipids are the most common class of preserved lipids in organic residues trapped in the porous clay matrix of archaeological ceramic vessels. The ubiquitous presence of fatty acids in animal fats and plant oils precludes identification of fat types by the solely molecular composition of residues. Hence, animal fats are identi…
The Cultural Evolution of Neolithic Europe. Euroevol Dataset 1
The datasets described in this paper comprise the core spatial and temporal structure of the Cultural Evolution of Neolithic Europe project (EUROEVOL), led by Professor Stephen Shennan, UCL. This is one of three datasets resulting from the EUROEVOL project, the other two comprising the faunal (EUROEVOL Dataset 2) and archaeobotanical (EUROEVOL Dataset 3) data (http://discovery.ucl.ac.uk/1469811/). The dataset offers the largest repository of arch…
Inferential mistakes in population proxies
The demographic response to Holocene climate change in the Sahara
The timing and development of Holocene human occupation in the now hyperarid Sahara has major implications for understanding links between climate change, demography and cultural adaptation. Here we use summed probability distributions from 3287 calibrated 14C dates from 1011 archaeological sites to demonstrate a major and rapid demographic shift between 10,500 and 5500 years BP. This event corresponds with the African Humid Period (AHP) and is s…
Reconstructing regional population fluctuations in the European Neolithic using radiocarbon dates
In a previous study we presented a new method that used summed probability distributions (SPD) of radiocarbon dates as a proxy for population levels, and Monte-Carlo simulation to test the significance of the observed fluctuations in the context of uncertainty in the calibration curve and archaeological sampling. The method allowed us to identify periods of significant short-term population change, caveated with the fact that around 5% of these p…
The chronology of culture
Archaeologists have long sought appropriate ways to describe the duration and floruit of archaeological cultures in statistical terms. Thus far, chronological reasoning has been largely reliant on typological sequences. Using summed probability distributions, the authors here compare radiocarbon dates for a series of European Neolithic cultures with their generally accepted ‘standard’ date ranges and with the greater precision afforded by dendroc…
Regional population collapse followed initial agriculture booms in mid-Holocene Europe
Following its initial arrival in SE Europe 8,500 years ago agriculture spread throughout the continent, changing food production and consumption patterns and increasing population densities. Here we show that, in contrast to the steady population growth usually assumed, the introduction of agriculture into Europe was followed by a boom-and-bust pattern in the density of regional populations. We demonstrate that summed calibrated radiocarbon date …
Bone growth, limb proportions and non-specific stress in archaeological populations from Croatia
These findings highlight the complexity of growth patterns in past populations and indicate that variation in environmental conditions such as diet and differences in the nature of non-specific stress lesions both exert a significant effect on long bone growth
