    CARTA: Body Modification - Questions Answers and Closing Remarks

    Permanent body modification is a unique and variable practice among humans, not observed in other mammals. Despite being costly and risky, it is regularly performed. Scientific understanding of this phenomenon is nascent, prompting a symposium aiming to assess current research status and prioritize questions for the next decade. The event brings together academics and industry practitioners, exploring historical and contemporary practices like tattooing, piercing, finger amputation, and cranial modification. The symposium aims to investigate the 'when' and 'where' of permanent body modification and understand the motivations behind it, considering personal justifications and scientific hypotheses.

    CARTA: Lip Plates in Ethiopia with Shauna LaTosky

    In the literature on lip plates in Southern Ethiopia there has been a strong emphasis on their socio-cultural importance and little information about their biocultural significance. Shauna LaTosky proposes that cultural keystone species theory and cultural keystone place theory could provide a useful frameworks for understanding relationships between the agro-pastoralist Mursi of Southern Ethiopia and the plant species and places that are integral to maintaining their cultural bodily practices. Keystone designations are applied here to the indigenous fruit tree lomay (Ximenia americana) and special clay pits in recognition of their role in the success of permanent body modification practices such as the piercing and stretching of women’s lower lips, but also in the promotion of health, social well-being and a sustainable environment.

    CARTA: The Recent History of Piercing Practices in Europe and North America with Paul King

    Across continents, material evidence of body piercing jewelry abounds in the archeological record. However, the varying procedures and processes of piercing, healing, and stretching these wounds for adornment remains unfamiliar to most archeologists. This talk discusses the early self-experimentations that led to the development of the Euro-American body piercing industry. From the late 19th throughout the 20th centuries shared personal correspondence, illustrations, and photographs document the adaptations, innovations, successes, and failures that came to coalesce a current community’s collective knowledge. Understanding the processes of these secretive explorations provides insights into many of the cross-cultural practices of the past for which no clear records remain.

    CARTA: Permanent Body Modification in Mesoamerica and Central America with Rosemary Joyce

    Archaeological research in Mexico and Central America reveals insights into cultural practices, focusing on the history of body modification. Examining long-term patterns helps unravel motivations for adoption, change, and abandonment of these practices. The talk emphasizes how body modification histories in this region illuminate shared identities across linguistic, ethnic, and political boundaries, while also highlighting distinctions within regional traditions and individual societies. It suggests that indigenous societies viewed the human body as shaped by the community, challenging the notion of a universal boundary between the natural body and the social person.

    CARTA: Female and Male Genital Modification with Ellen Gruenbaum

    This talk offers an overview of the many forms of permanent genital modifications embedded in human cultures, where they occur, the reasons why, the archaeological investigations of origins, and future trends. Included are female clitoridectomy, excision, infibulation, and other practices that affect about five percent of females worldwide; and the male practices that affect one-third of males: circumcision, superincision, and subincision. Why have so many cultures invented and preserved these modifications as part of their valued heritage? Controversies abound: the current human rights opposition to all female practices is met with backlash, and others question the “justifications” for continuing male circumcision.

    CARTA: Dental Ablation and Facial Piercing in Late Pleistocene Southwestern Asia and Africa with John Willman

    Bioarchaeological studies of Pleistocene populations, examining practices like tooth ablation, facial piercing, and cranial modification, contribute to our understanding of social identities and population dynamics. Recent analyses of Ohalo II H2 in southwestern Asia and Oldupai Hominid 1 in Tanzania reveal dental evidence of intentional body modifications. Ohalo II H2 likely represents the earliest case of intentional incisor ablation in Southwest Asia, a common practice in Iberomaurusian and Natufian cultures. Oldupai Hominid 1 exhibits dental wear suggestive of facial piercings, a previously unknown practice in Late Pleistocene/Early Holocene East Africa. These early cases shed light on the cultural practices and social identities of Pleistocene populations.

    CARTA: Permanent Body Modification: Archaeological and Early Historical Evidence with Brea McCauley

    Today, permanent body modification (PBM) is very popular. Studies suggest that well over a billion living people have experienced one or more types of PBM. But what is the history of PBM? When did the different types originate? Were they invented recently, or do they have a long history? Did they appear simultaneously or at different times? This presentation examines evidence in non-human animals and extinct hominins, delving into early archaeological and historical records of seven main PBM types: tattooing, scarification, amputation, piercing, genital modification, dental modification, and bone shaping. Strong evidence supports human PBM for at least 15,000 years, with intriguing hints suggesting a history dating back as far as 80,000 years.

    CARTA: A Multistep Evolutionary Scenario for the Culturalization of the Human Body with Francesco d'Errico

    Our ability to adapt our bodies to culture has ancient origins. We suggest a timeline for how the culturalization of the human body evolved, starting around 500-300 thousand years ago. This timeline highlights key moments at 140 thousand years, 70 thousand years, and 45 thousand years, followed by a faster pace linked to the rise of production economies. The underlying idea is a gradual growth in the complexity of technologies shaping the body, along with increased time and effort invested in obtaining and transforming necessary materials. Simultaneously, the development of symbolic codes required the creation of specific cognitive functions and neural circuits, allowing for the decoding of intricate messages conveyed by these cultural practices. These practices likely became more intricate in terms of techniques, symbolic codes, and the involvement of specialized individuals over time to ensure their continuation and potential further development.
