Firewood, food and niche construction : the potential role of Mesolithic hunter-gatherers in actively structuring Scotland's woodlands.

Over the past few decades the potential role of Mesolithic hunter–gatherers in actively constructing their own niches, through the management of wild plants, has frequently been discussed. It is probable that Mesolithic hunter–gatherers systematically exploited specific woodland resources for food and fuel and influenced the ‘natural’ abundance or distribution of particular species within Mesolithic environments. Though there has been considerable discussion of the pollen evidence for potential small-scale human-woodland manipulation in Mesolithic Scotland, the archaeobotanical evidence for anthropogenic firewood and food selection has not been discussed in this context. This paper assesses the evidence for the active role of Mesolithic hunter–gatherer communities in systematically exploiting and managing woodlands for food and fuel in Scotland. While taphonomic factors may have impacted on the frequency of specific species in archaeobotanical assemblages, it is suggested that hunter–gatherers in Mesolithic Scotland were systematically using woodland plants, and in particular hazel and oak, for food and fuel. It is argued that the pollen evidence for woodland management is equivocal, but hints at the role of hunter–gatherers in shaping the structure of their environments, through the maintenance or creation of woodland clearings for settlement or as part of vegetation management strategies. It is proposed that Mesolithic hunter–gatherers may have actively contributed to niche construction and that the systematic use of hazel and oak as a fuel may reflect the deliberate pruning of hazel trees to increase nut-yields and the inadvertent – or perhaps deliberate – coppicing of hazel and oak during greenwood collection

Mesolithic projectile variability along the southern North Sea basin (NW Europe) : hunter-gatherer responses to repeated climate change at the beginning of the Holocene

This paper investigates how former hunter-gatherers living along the southern North Sea coast in NW Europe adapted to long-term and short-term climatic and environmental changes at the beginning of the Holocene. It is argued that contemporaneous hunter-gatherers repeatedly changed their hunting equipment in response to changing climate and environment, not just for functional reasons but mainly driven by socio-territorial considerations. Based on a Bayesian analysis of 122 critically selected radiocarbon dates a broad chronological correlation is demonstrated between rapid changes in the design and technology of stone projectiles and short but abrupt cooling events, occurring at 10.3, 9.3 and 8.2 ka cal BP. Combined with the rapid sea level rises and increased wildfires these climatic events probably impacted the lifeways of hunter-gatherers in such a way that they increasingly faced resource stress and competition, forcing them to invest in the symbolic defense of their social territories

Violence and warfare in prehistoric Japan

The origins and consequences of warfare or largescale intergroup violence have been subject of long debate. Based on exhaustive surveys of skeletal remains for prehistoric hunter-gatherers and agriculturists in Japan, the present study examines levels of inferred violence and their implications for two different evolutionary models, i.e., parochial altruism model and subsistence model. The former assumes that frequent warfare played an important role in the evolution of altruism and the latter sees warfare as promoted by social changes induced by agriculture. Our results are inconsistent with the parochial altruism model but consistent with the subsistence model, although the mortality values attributable to violence between hunter-gatherers and agriculturists were comparable

Dental Microwear From Natufian Hunter-Gatherers and Early Neolithic Farmers: Comparisons Within and Between Samples

Microwear patterns from Natufian hunter-gatherers (12,500–10,250 bp) and early Neolithic (10,250–7,500 bp) farmers from northern Israel are correlated with location on facet nine and related to an archaeologically suggested change in food preparation. Casts of permanent second mandibular molars are examined with a scanning electron microscope at a magnification of 500×. Digitized micrographs are taken from the upper and lower part of facet nine. Microwear patterns are recorded with an image-analysis computer program and compared within and between samples, using univariate and multivariate analyses. Comparisons within samples reveal a greater frequency of pits on the lower part of the facet among the farmers, compared to the upper part. Microwear does not vary over the facet among the hunter-gatherers. Comparisons between samples reveal larger dental pits (length and width) and wider scratches among the farmers at the bottom of the facet, compared to the hunter-gatherers. Microwear does not vary between samples at the top of the facet. The microwear patterns suggest that the Natufian to early Neolithic development led to a harder diet, and this is related to an archaeologically suggested change in food processing. The harder diet of the early farmers may have required higher bite forces that were exerted at the bottom of facet nine, in the basin of the tooth

A war-prone tribe migrated out of Africa to populate the world.

Of the tribal hunter gatherers still in existence today, some lead lives of great violence, whereas other groups live in societies with no warfare and very little murder^1,2,3,4,5^. Here I find that hunter gatherers that belong to mitochondrial haplotypes L0, L1 and L2 do not have a culture of ritualized fights. In contrast to this, almost all L3 derived hunter gatherers have a more belligerent culture that includes ritualized fights such as wrestling, stick fights or headhunting expeditions. This appears to be independent of their environment, because ritualized fights occur in all climates, from the tropics to the arctic. There is also a correlation between mitochondrial haplotypes and warfare propensity or the use of murder and suicide to resolve conflicts. This, in the light of the “recent out of Africa” hypothesis”^6,7^, suggests that the tribe that left Africa 80.000 years ago performed ritualized fights. In contrast to the more pacific tradition of non-L3 foragers, it may also have had a tendency towards combat. The data implicate that the entire human population outside Africa is descended from only two closely related sub-branches of L3 that practiced ritual fighting and probably had a higher propensity towards warfare and the use of murder for conflict resolution. This may have crucially influenced the subsequent history of the world

Nutritional Status, Activity Pattern, and Dietary Intake among the Baka Hunter-gatherers in the Village Camps in Cameroon

The nutritional status of 75 male and 73female pygmy hunter-gatheres were surveyed as well as the daily physical activity, energy and intake of major nutrients, and total energy expenditure were examined for two married couples of the Baka hunter-gatherers in Cameroon. The average stature was intermediate relative to other Pygmy hunter-gatherers, and the subjects were generally well nourished. Despite the limited sample size and survey duration, the results indicated that the energy intake and energy expenditure of Cameroonian Baka hunter-gatherers were relatively low, which may enable them to adapt to low food availability in the village camps during the rainy season

Hunter-Gatherer Studies: The Importance of Context

Anthropological and behavioral ecological studies of living hunter-gatherers have flourished since the 1960's. Researchers have developed and followed a variety of paradigms, each with its own assumptions and objectives, based on the behavior of hunter-gatherer communities. I agree here that in order to evaluate the validity of the use of a specific hunter-gatherer group for particular paradigmatic purposes, details of the historical and social context of the group are needed. The use of an inappropriate group, as determined by its context, can call into question the conclusions of a study. A method for classifying hunter-gatherer groups according to progressive stages of historical contact and interrelations with agricultural neighbors is proposed. The use of this classification system can aid in analyzing important questions concerning the hunter-gatherer adaptation: what explains immediate return and delayed return systems? Why do hunter-gatherers persist today? Can contemporary hunter-gatherers be used as valid models or analogues for prehistoric human behavior? The answers to these questions are related to the ultimate question: Why study hunter-gatherers

Pottery spread in ancient foragers

Although we have been able to track how cultural innovations spread among farming populations in prehistoric Europe, we know relatively little about this among European hunter-gatherers. Dolbunova et al. use a range of techniques to shed light on how the making and use of pottery spread among early-to-mid-Holocene hunter-gatherers west of the Urals
