Children at play: The role of novices in the production of Europe's earliest Upper Paleolithic ceramics.

Although archaeologists are learning more about the lives of Upper Paleolithic children, the significant contributions they made to the welfare of their communities, including their role in craft production, remain understudied. In the present study, we use high resolution photographs of 489 ceramic artifacts from Dolní Věstonice I and II, Pavlov I and VI, and Předmostí, five archaeological sites in Czechia (ca. 30,000 BP) to address two questions: 1.

An assessment of puberty status in adolescents from the European Upper Paleolithic.

Childhood and adolescence are two life-history stages that are either unique to humans, or significantly expanded in the human life course relative to other primates. While recent studies have deepened our knowledge of childhood in the Upper Paleolithic, adolescence in this period remains understudied. Here, we use bioarchaeological maturational markers to estimate puberty status of 13 Upper Paleolithic adolescents from sites in Russia, Czechia, and Italy to 1) evaluate the feasibility of the application of bioarchaeological puberty assessment methods to Upper Paleolithic (Homo sapiens) skeletal individuals, 2) estimate the timing and tempo of puberty in Upper Paleolithic adolescents compared to other archaeological populations analyzed using the same method, and 3) characterize adolescence in the Upper Paleolithic by contextualizing the results of this puberty assessment with data on individual and population-level health, morbidity and burial practices.

Children and innovation: play, play objects and object play in cultural evolution.

Cultural evolutionary theory conceptualises culture as an information-transmission system whose dynamics take on evolutionary properties. Within this framework, however, innovation has been likened to random mutations, reducing its occurrence to chance or fortuitous transmission error. In introducing the special collection on children and innovation, we here place object play and play objects - especially functional miniatures - from carefully chosen archaeological contexts in a niche construction perspective.

Care of Infants in the Past: Bridging evolutionary anthropological and bioarchaeological approaches.

The importance of care of infants and children in palaeoanthropological and human behavioural ecological research on the evolution of our species is evident in the diversity of research on human development, alloparental care, and learning and social interaction. There has been a recent surge of interest in modelling the social implications of care provision for people with serious disabilities in bioarchaeology. However, there is a lack of acknowledgement of infant and child care in bioarchaeology, despite the significant labour and resources that are required, and the implications this has for health outcomes within societies.

Adolescence and innovation in the European Upper Palaeolithic.

Childhood and adolescence are two stages of development that are unique to the human life course. While childhood in the Pleistocene has received considerable attention in recent years, adolescence during the same period remains an understudied area of research. Yet it is during adolescence that key social, physical and cognitive milestones are reached.

The role of play objects and object play in human cognitive evolution and innovation.

In this contribution, we address a major puzzle in the evolution of human material culture: If maturing individuals just learn their parental generation's material culture, then what is the origin of key innovations as documented in the archeological record? We approach this question by coupling a life-history model of the costs and benefits of experimentation with a niche-construction perspective. Niche-construction theory suggests that the behavior of organisms and their modification of the world around them have important evolutionary ramifications by altering developmental settings and selection pressures. Part of Homo sapiens' niche is the active provisioning of children with play objects - sometimes functional miniatures of adult tools - and the encouragement of object play, such as playful knapping with stones.

How to make stone soup: Is the "Paleo diet" a missed opportunity for anthropologists?

For the past few years, people everywhere have been "going Paleo." Websites and social media touting the benefits of eating a "Paleo diet" and following a "Paleolithic life style" serve as calls to arms for health-conscious individuals seeking information about the latest health and fitness trends. Many of these people participate in programs such as Crossfit, which involve major social and life-style modification components and therefore facilitate the dissemination of dietary fads.

The Nature of Culture: an eight-grade model for the evolution and expansion of cultural capacities in hominins and other animals.

Tracing the evolution of human culture through time is arguably one of the most controversial and complex scholarly endeavors, and a broad evolutionary analysis of how symbolic, linguistic, and cultural capacities emerged and developed in our species is lacking. Here we present a model that, in broad terms, aims to explain the evolution and portray the expansion of human cultural capacities (the EECC model), that can be used as a point of departure for further multidisciplinary discussion and more detailed investigation. The EECC model is designed to be flexible, and can be refined to accommodate future archaeological, paleoanthropological, genetic or evolutionary psychology/behavioral analyses and discoveries.

A place in time: situating Chauvet within the long chronology of symbolic behavioral development.

Since the discovery of the Grotte Chauvet (Ardèche, France) in the mid-1990s, there has been a debate regarding the accuracy of assigning this site to the Aurignacian period. The main argument stems from a perceived lack of agreement between the radiocarbon age of the imagery (>32,000 years BP [before present]) and its stylistic complexity and technical sophistication, which some believe are more typical of the later Upper Paleolithic. In this paper we first review the evidence for symbolic behavior among modern humans during the Aurignacian in order to explore the question of whether Chauvet's images are anachronistic.
