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.

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.

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.

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.

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.

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.

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.

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.

This talk presents a new account of the development of professional tattooing in Britain and America since the late 19th century. Research based exclusively in primary sources reveals that the story of what kickstarted the creation of commercial tattooing, and what sustained it, ultimately becomes intelligible as a small and interconnected network of transnational artists and – crucially – clients. These newly clarified networks problematise both the date and form of the customary notion of a “Tattoo Renaissance” in the 1970s and 80s. Moreover, this research presents a more diverse account of the transmission of design, technology and influence throughout Euro-American tattooing than had previously been understood both within the industry, and beyond. Research is drawn from Dr Lodder’s next book on the history of the modern Euro-American tattoo industry, due to be published in late 2024 with Yale University Press.

This talk explores the 1000-year practice of "footbinding" in ethnically Han Chinese families, involving modifying young girls' feet by wrapping the toes under the sole, often resulting in broken toes. Two main hypotheses—Labor Market and Evolutionary Social Sciences—are considered for explaining the origins, maintenance, and cessation of footbinding. This talk presents evidence from autopsy results, medical examinations, anthropological records, interviews, and historical texts. It argues that evolutionary social and psychological principles related to hypergyny, mate guarding, parental competition, mate competition, and paternal uncertainty offer better explanations for the origins and maintenance of footbinding than labor market factors.

Comparative Anthropogeny (CompAnth) is the study of distinctly human traits and characteristics in the context of comparisons with our closest living relatives, the “great apes.” This symposium, the third of CARTA's CompAnth series, will present a collection of distinctive human traits, ranging from molecular, cellular, and anatomical biology to behavioral, societal, and cultural features. Given the large number of human traits for which no counterparts have yet been described in nature, the limitations of the comparative method will also be addressed and alternative approaches to the singularity that is the human phenomenon will be discussed. The goal is a better understanding of human origins and a full appreciation of our species’ planet altering effects.

Human language is a strong contender for the title of most often named species-specific feature in the literature. But why is that? In this talk, Eva Wittenberg explores what we could mean by "human language", and how different conceptions of language inevitably lead to different answers about whether it is species-specific. While syntax is a central feature, it is only one of several, and the uniqueness of human language is that it arose from a combination of, perhaps, ordinary ingredients.

Human ovulation lacks visible signs, unlike chimpanzees and bonobos with conspicuous genital swellings during fertility. This led to the concept of "concealed ovulation," seen as a human adaptation. Proposed reasons include encouraging paternal investment, confusing paternity to deter infanticide, enabling secret mating and female choice, and reducing female rivalry. Many non-human primates also have unsignaled ovulation. While self-reported human mating doesn't match ovulation, debates persist on subtle reproductive cycle influences. Some cultures use menstrual taboos to disclose fertility status. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 39275]

Life history theory suggests that inter-birth intervals (IBIs) depend on a trade-off between maternal investment in current and future offspring, influenced by the mother's energy and somatic maintenance. Normally, IBI aligns with maternal and infant body size, larger relative infant size leading to slower breeding. In contrast, humans have relatively shorter IBIs due to cooperative breeding, support from the social group. Some other species with cooperative behaviors also exhibit shorter IBIs, possibly aided by factors like meat-eating enabling early weaning around 2.5 million years ago in the Homo lineage.

High-altitude adaptation stands out as one of the most notable examples of evolution within our species. Despite similar challenges of decreased oxygen availability, human groups on different continents have followed unique evolutionary trajectories. I will discuss how genomic, molecular, and physiological discoveries reveal key insights into human-specific evolutionary changes, examine comparative findings and limitations, and consider alternative approaches for understanding distinct facets of this extraordinary human phenomenon.

The human genome contains segments of DNA with non-human origins. This introgressed genetic material is remnants of mating events between early modern humans and their archaic contemporaries (e.g., Neanderthals and Denisovans). In this talk, Andrew Schork will review the evidence for such genetic material, its consequences on phenotypic diversity in modern humans, and discuss if this process - archaic introgression - is typical among other great ape species.

The most complex organizations in the living world beside those of humans are the colonies of ants. Mark Moffett will argue that points of comparison between sharply different organisms like ants and humans are exceptionally valuable to science, and indeed that modern humans are in many ways much more like certain ants than we are to our nearest relatives, the chimpanzees. He considers such issues as the role of individuality and group identity in ant societies; the advantages to ants of flat organizations without leaders or hierarchies; and what we can learn from ants with respect to direct and indirect communication, self-organization, job specialization, labor coordination, and global domination.

Ethnology, also known as cross-cultural analysis or comparative anthropology, involves comparing features of historically documented human societies. It has historical ties to archaeology, with notable figures like Augustus Pitt Rivers and Lewis Binford being proponents. Despite this, it's not commonly seen as a vital archaeological tool. This talk argues for its importance, citing both theoretical and practical benefits. Including ethnology in archaeological education can expedite our understanding of patterns in the archaeological record.

Since humans split from their primate ancestors, their brains evolved with a larger mass relative to body weight, more cortical neurons, and distinct connectivity patterns. Human neurons mature more slowly, a trait known as neoteny, likely influencing these differences. Gene regulation, not new genes, may underlie species differences, particularly in the primate lineage. The role of these regulatory mechanisms in human neuron development remains poorly understood. This lecture explores the molecular factors affecting prolonged human neuron maturation and its implications for human development and neurodevelopmental diseases.

We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research suggests a complex history, with population structures dating back to about 120,000-135,000 years ago. Early populations had connections, or gene flow, for hundreds of thousands of years. These "weakly structured stem" models explain genetic diversity that was once thought to come from other hominin species. Unlike previous ideas of interbreeding with archaic humans, our models predict that fossils from these populations should be genetically and physically similar. This variability in theories stems from not considering different possibilities, highlighting the importance of exploring various models to gain more accurate insights into our deep history.

The human penchant for storytelling is universal, early-developing, and profoundly culture-shaping. Stories (folk tales, narratives and myths) influence the costs of social transactions and organize societies at every scale of human interaction. Story as a mode of communication is also unprecedented in the animal kingdom: although we are compelled to tell stories about other animals, they are not likewise compelled to tell stories about us (or anything else, for that matter). Even our ability to manage urgent human problems such as global health and climate change are affected by the stories and myths humans choose to tell. This symposium explores several stories about how the evolution of story-telling shaped, and continues to shape, the human epoch.

Animals and tricksters are highly prominent beings in the mythology of the San Bushmen of southern Africa, as well as of hunter-gatherers in other regions of the world. Their actions and interactions provide the plot lines for most of the stories people tell about myth time. Why are these two beings so preeminent in San mythology and storytelling? Is there a connection between the two beings? Mathias Guenther discusses these two questions and the answer reveals a deep – and deep-rooted –mystical connection also between animals and humans. The hunting-gathering people that provide the cultural context for my talk are the San Bushmen of southern Africa, amongst whom I have done ethnographic field work. I will also consider hunter-gatherers from other parts of the world, both from present or recent times and from prehistory. These considerations may shed some light on certain aspects of prehistoric cave paintings.

Political, financial and environmental crises coupled to the rise of social media have, in recent years, created a perfect storm of mis- and disinformation that leverage long standing reservoirs of belief within and across communities. These stories on social media mirror face-to-face storytelling and other storytelling environments in that they allow for the negotiation of cultural ideology (norms, beliefs, values), yet they also change the scope, speed and amplification of that storytelling. Importantly, storytelling has real world effects, and often motivates people to take action. We present a graphical model of the underlying narrative frameworks, estimated from the data itself, and show how various network based methods can form the basis for understanding the narrative coherence—and their possible outcomes—even when the discussions on social media are incomplete and noisy, as conversations in real life often are.

In the foundational texts of Western civilisation (the Bible, Iliad), plagues are symbols of divine retribution, signifying Godly displeasure with human misdeeds. But in Thucydides’ classic account of the mysterious plague that swept Athens in 430 BC, Camus’s La Peste, and Emily St John Mandel’s Station Eleven, literary accounts of plagues and pandemics are also morality tales and metaphors for the dissolution of the social bonds necessary for the functioning of modern societies. In this talk, I bring the history of plague writing into dialogue with the history of trust, to examine what plague texts tell us about our foundational myths and our obsession with calamities and crises.

As the global response to climate change drives a profound reevaluation of our interaction with fire, there's a timely opportunity to delve into the roots of our connection with combustion. Archaeologist Michael Chazan uncovers early traces of human fire usage at Wonderwerk Cave in South Africa and Evron Quarry in Israel. Chazan contends that it's more apt to consider the emergence of a dynamic bond between humans and fire rather than pinpointing a singular origin. This symbiotic relationship is defined by how fire intertwines technology and society, the tangible and intangible, adaptation and the sacred. Join us in exploring this intricate interplay, shedding light on the fusion of humanity and the elemental force that has shaped civilizations.

Humans have been telling stories about animals as long as humans have been telling stories. One story humans tell about animals is the one about how, with enough care and patience humans might one day listen to the stories animals themselves have to tell. Some folks see this story as nonfiction, a truth about animals manifest in the dance of bees, the grunts of monkeys, the antics of their dogs and cats, or the signs produced by trained gorillas. In this talk, I attempt examine these conflicting views. Despite the fact that animals do not sit around fires telling stories, are their minds organized in story-like formats? Do their mental representations of the events of the past, present and future constitute general narratives? Do they construct and reflect on their own personal narratives? And finally, and perhaps more paradoxically, are our scientific answers to these questions a better reflection of the internal world of animals or the humans who study them?

The hunting hypothesis proposes that the dietary shift to meat procurement was the catalyst favoring a suite of transformative human biological and behavioral adaptations. Evolutionary changes in the human diet are associated with the emergence of food sharing, the division of labor and pooled energy budgets. To balance this discussion, I revisit several misconceptions linked to the hunting hypothesis. Revising myths about the centrality of hunting to more closely reflect the archaeological and ethnographic records has important implications for updating the entrenched emphasis on male behaviors.

Some 350 to 400,000 years ago when our ancestors gained control of fire, the day was extended to provide many hours for social interaction, undisturbed by economic activities. How were those hours spent in societies that only had firelight after nightfall? In most preindustrial societies, music, dance, healing and storytelling fill the darkness. Myths and legends create common understandings on such matters as the origins of humans, social groups, rituals or features of the landscape. Hilarious trickster traditions explore the successes and failures of those who have the pluck to break with social norms. Stories about the adventures of real people add other dimensions, a topic Polly Wiessner addresses here.

Why are humans a compulsively storytelling species? Why especially do we invent stories, why do we tell one another stories that both teller and audience know to be untrue?

For more than a century, folklorists have indexed a vast number of the world’s folkloric narratives according to varying structures (i.e. tale types) and to discrete elements (i.e. motifs) that commonly appear across cultures. This talk will introduce and analyze several examples of motifs indexed in folklorist Stith Thompson’s system. Ultimately, I ask whether stories about origins (human origins or otherwise) might constitute a genuine cultural universal? And if so, what might the folkloric representations of human origins say about a contemporary science of anthropogeny?

The origin of humans is a difficult scientific problem in evolution that is grounded in biology and molded by culture. Recent advances in neuroscience and artificial intelligence have led to synergies and surprising new hypotheses. Mysteries such as the origin of language and human sociality are being illuminated by these advances.

Pragmatics poses a headache to developers of artificial systems. But how did language evolve to efficiently relay so much pragmatic trickery? Eva Wittenberg presents a new paper that builds on the idea that grammar evolved gradually, and with it, pragmatics. We argue that the simpler a grammar is, the stronger the reliance on pragmatic inferences for many aspects of meaning, including even basic questions such as who did what to whom. As grammars gradually evolve towards more complex systems, these coarse pragmatic inferences give way to pragmatic processes that are different in character: Syntax, semantics, and the lexicon evolve to contain reliable and systematic triggers for highly structured pragmatic phenomena. Our account thus links a gradualist scenario of the evolution of syntax that triggers distinct qualitative processes in pragmatic reasoning.

Parallel Architecture is a theory of the mental representations involved in the language faculty. These representations are organized in three orthogonal dimensions or levels: phonology, syntax, and semantics, correlated with each other through interface links. Words are encoded in all three levels and serve as part of the interface between sound and meaning. In the representation of an entire sentence, the words are spread out across the combinatoriality of the three levels. An important requirement for a theory of language is that it must offer an account of how we can talk about what we see. It is proposed that conceptual structure in language interfaces with a level of physical space – which in turn interfaces with visual, haptic, and proprioceptive perception, and with the planning of action. Thus, the basic principles of the Parallel Architecture for language can be extended to major aspects of mental function.

Vocal learning is one of the most critical components of spoken language. It has only evolved several independent times among mammals and birds. Although all vocal learning species are distantly related and have closer relatives that are non-vocal learners, humans and the vocal learning birds have evolved convergent forebrain pathways that control song and speech imitation and production. Erich Jarvis presents an overview of the various biological hypothesis of what makes vocal learning and spoken language special, how it evolved, and what differs about the molecular and neural mechanisms compared to other behavioral traits.

Common sense is shared knowledge about people and the physical world, enabled by the biological brain. It comprises intuitive psychology, intuitive physics, and intuitive sociality. Unlike deep neural networks, common sense requires only limited experience. Human intelligence has evolved to deal with uncertainty, independent of whether big or small data are available. Complex AI algorithms, in contrast, work best in stable, well-defined situations such as chess and Go, where large amounts of data are available. This stable-world principle helps to understand what statistical algorithms are capable of and distinguish it from commercial hype or techno-religious faith. Gerd Gigerenzer introduces the program of psychological AI, which uses psychological heuristics to make algorithms smart. What we need is a fusion of the adaptive heuristics that embody common sense with the power of machine learning.

The emergence of language is routinely regarded as a major (or even the main) evolutionary transition in our species’ history. Much less attention and awe has been dispensed to the fact that humans evolved the capacity to successfully create, learn, and use a myriad of different languages which, while similar in some aspects, are radically different in many others. In this presentation, I will argue that these differences have observable consequences for non-linguistic aspects of cognition and behavior. Finally, I will discuss how these effects play out in the design, testing, and deployment of AI, as the linguistic peculiarities of behemoth languages like English are extrapolated to the world’s languages.

Highly organized social groups require well-structured and dynamic communication systems. Naked mole-rats form some of the most rigidly structured social groups in the Animal Kingdom, exhibiting eusociality, a type of highly cooperative social living characterized by a reproductive division of labor with a single breeding female, the queen. Using machine learning techniques we demonstrated that one vocalization type, the soft chirp, encodes information about individual identity and colony membership. Colony specific vocal dialects can be learned early in life--pups that were cross-fostered acquire the dialect of their adoptive colonies. We also demonstrate that vocal dialects are influenced in part by the presence of the queen. Alison Barker summarizes these findings and highlight our current work investigating how social and vocal complexity evolved in parallel in closely related species throughout the Bathyergidae family of African mole-rats.

Large language models (LLMs) have now achieved many of the longstanding goals of the quest for generalist AI. While LLMs are still very imperfect (though rapidly improving) in areas like factual grounding, planning, reasoning, safety, memory, and consistency, they do understand concepts, are capable of insight and originality, can problem-solve, and exhibit many faculties we have historically defended vigorously as exceptionally human, such as humor, creativity, and theory of mind. At this point, human responses to the emergence of AI seem to be telling us more about our own psychology, hopes and fears, than about AI itself. However, taking these new AI capacities seriously, and noticing that they all emerge purely from sequence modeling, should cause us to reassess what our own cerebral cortex is doing, and whether we are learning what intelligence, machine or biological, actually is.

Evolution always presented life forms with new challenges -- due to changes in weather, terrain, competition between different organisms, and other reasons. To increase the chance of survival, instead of solely optimizing current performance, it is in an agent's interest to maximize its ability to adapt to changes. Possibly this old evolutionary trait manifests itself in modern humans in their ability to adapt to new tasks and challenges quickly. Even if we consider a lifetime of a human, the ability to adapt is critical. An open question is what enables humans to adapt, a trait that modern AI systems lack. Frivolous play prepares infants for future life by laying down the foundation of a high-level experimentation framework to quickly understand how things work in new environments for constructing goal-directed plans. Pulkit Agrawal discusses how the idea of experimentation can be leveraged to construct robots that improve with experience and solve novel problems presented to them.

Feedback interconnections are widespread in the brain; yet clear explanations for most of them are currently lacking. Carmen Amo Alonso and John Doyle explore current experimental evidence on the relationship between the auditory and motor parts of the brain during speech perception and production. These models provide a plausible explanation for how the structure of language, as described in the Parallel Architecture, is implemented in the brain. Together, they provide a plausible account for how the Parallel Architecture of language originates as a result of functional constrains in the sensorimotor system. They compare the brain’s implementation of the language capacity with other cognitive capacities, such as vision or motor planning and control, which also have massive internal feedbacks that our new theory explains for the first time.

Anthropogeny, has provided many new discoveries over the past decade, ranging from new fossil finds to ancient DNA data, including from extinct hominins. New methods and multi-disciplinary collaborations are providing exciting new insights into the complicated evolutionary journey that gave rise to our species. However, we remain far from understanding some of the most striking human-specific characteristics: the reasons for our bipedality, the factors selecting for our dexterity at creating and using tools, and the true age of fire use in our distant ancestors.

Anthropogeny, has provided many new discoveries over the past decade, ranging from new fossil finds to ancient DNA data, including from extinct hominins. New methods and multi-disciplinary collaborations are providing exciting new insights into the complicated evolutionary journey that gave rise to our species. However, we remain far from understanding some of the most striking human-specific characteristics: the reasons for our bipedality, the factors selecting for our dexterity at creating and using tools, and the true age of fire use in our distant ancestors. This CARTA symposium features advisory committee members who highlight where they hope future efforts should be focused and what type of novel collaborations are most promising for improving our understanding of the human phenomenon.
