An Interaction Model for Resource Implement Complexity Based on Risk and Number of Annual Moves
Different hypotheses identifying factors affecting the complexity of implements used to obtain food resources by hunter-gatherer groups are assessed with regression analysis. A regression model based on interaction between growing season as a proxy measure for risk and number of yearly moves fits data on the complexity of implements for 20 hunter-gatherer groups. The interaction model leads to a division of hunter-gatherer groups into two subgroups that correspond to collector vs. forager strategies for procuring resources. Implications of the interaction model for the evolution of complex implements are discussed.

Behavioural mimicry as an indicator of affiliation
Previous research has shown that behavioural mimicry fosters affiliation, and can be used to infer whether people belong to the same social unit. However, we still know very little about the generalizability of these findings and the individual factors involved. The present study intends to disentangle two important variables and assess their importance for affiliation: the matching in time of the behaviours versus their matching in form. In order to address this issue, we presented participants with short videos in which two actors displayed a set of small movements (e.g. crossing their legs, folding their arms, tapping their fingers) arranged to be either contingent in time or in form. A dark filter was used to eliminate ostensive group marks, such us phenotype or clothing. Participants attributed the highest degree of affiliation to the actors when their subsequent movements matched in form, but were delayed by 4–5 seconds, and the lowest degree when the timing of their movements matched, but they differed in form. To assess the generalizability of our findings, we took our study outside the usual Western context and tested a matching sample of participants from a traditional small-scale society in Kenya. In all, our results suggest that movements are used to judge the degree of affiliation between two individuals in both large- and small-scale societies. While moving in different ways at the same time seems to increase the perceived distance between two individuals, movements which match in form seem to invoke closeness.

Identity, Kinship, and the Evolution of Cooperation
Extensive cooperation among biologically unrelated individuals is uniquely human. It would be surprising if this uniqueness were not related to other uniquely human characteristics, yet current theories of human cooperation tend to ignore the human aspects of human behavior. This paper presents a theory of cooperation that draws on social, cultural, and psychological aspects of human uniqueness for which current theories have little or no explanation. We propose that the evolution of human cooperative behavior required (1) a capacity for self-sustained, self-referential thought manifested as an integrated worldview, including a sense of identity and point of view, and (2) the cultural formation of kinship-based social organizational systems within which social identities can be established and transmitted through enculturation. Human cooperative behavior arose, we argue, through the acquisition of a culturally grounded social identity that included the expectation of cooperation among kin. This identity is linked to basic survival instincts by emotions that are mentally experienced as culture-laden feelings. As a consequence, individuals are motivated to cooperate with those perceived culturally as kin, while deviations from expected social behavior are experienced as a threat to one’s social identity, leading to punishment of those seen as violating cultural expectations regarding socially proper behavior.

The rich detail of cultural symbol systems
The goal of forming a science of intentional behavior requires a more richly detailed account of symbolic systems than is assumed by the authors. Cultural systems are not simply the equivalent in the ideational domain of culture of the purported Baldwin Effect in the genetic domain.

The substance of cultural evolution: Culturally framed systems of social organization
Models of cultural evolution need to address not only the organizational aspects of human societies, but also the complexity and structure of cultural idea systems that frame their systems of organization. These cultural idea systems determine a framework within which behaviors take place and provide mutually understood meanings for behavior from the perspective of both agent and recipient that are critical for the coherence of human systems of social organization.

Artifact Classification
Archaeologists have been developing artifact typologies to understand cultural categories for as long as the discipline has existed. Dwight Read examines these attempts to systematize the cultural domains in premodern societies through a historical study of pottery typologies. He then offers a methodology for producing classifications that are both salient to the cultural groups that produced them and relevant for establishing cultural categories and timelines for the archaeologist attempting to understand the relationship between material culture and ideational culture of ancient societies. This volume is valuable to upper level students and professional archaeologists across the discipline.

Tasmanian Knowledge and Skill: Maladaptive Imitation or Adequate Technology?
A recent article has suggested that maintenance of complex tools and associated tasks in a group depends on the presence of skilled individuals to serve as targets for imitation. The expected number of skilled target individuals, it is argued, relates to the population size. It is predicted that population size and maximum complexity of tools and/or tasks should correlate, hence a decrease in population size could lead to maladaptive loss of skills. Data from Tasmania are said to support the argument. However, the argument neither agrees with the archaeological data from Tasmania nor ethnographic observations on hunter-gatherer societies. Instead of being an example of a group that underwent maladaptive loss, the indigenous people of Tasmania appear to have used tools sufficient for the tasks at hand. An alternative model is proposed that distinguishes between motor skills and knowledge needed to do tasks effectively and takes into account assessment of the time cost for developing skills. Loss of skills more likely relates to change in the mode of resource procurement or change in technology rather than a shortage of skilled, target individuals due to decrease in population size.
