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...

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...

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...

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...

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...

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...

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....

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? Why do many of us come to believe some invented stories? What difference has our compulsion to tell stories made to us as individuals, societies, and a species? How do we understand stories so seemingly effortlessly? Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show...

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...

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. This CARTA symposium will be explored by researchers at the frontiers of A.I., machine learning, language and sociality. Series: "CARTA - Center for Academic...

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,...

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...

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...

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...

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...

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...

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...

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...

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...
