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.

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.

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? 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 ID: 38995]

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. This CARTA symposium will be explored by researchers at the frontiers of A.I., machine learning, language and sociality.

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.

Current knowledge of our deep past is primarily derived from ancient fossils of our ancestors that paleoanthropologists search for and discover in some of the most remote areas of the world. In the last two decades, significant fossil discoveries have been made and these discoveries have re-written some parts of our deep past. However, the fossil record is still far from complete, primarily due to the absence of fossils from some critical geological times and the lack of robust samples for the species already identified. The best way to fill temporal gaps in the fossil record and meaningfully increase the sample size is by conducting surveys and exploration to locate new areas of paleoanthropological significance. If we want to fully understand our evolutionary history, especially how we became who we are today and where we are going, continued paleoanthropological fieldwork is of paramount importance.

For the past 30 years, the frontiers of language science have been in the areas of neurolinguistics and genetics, both of which arose in conjunction with new technologies emerging in the 1990s. It is probably safe to say that these trends will continue apace as technology in these areas continues to advance, allowing for increasingly sophisticated and fine-grained analysis. From its inception, the study of language has been inextricably linked with cultural anthropology and the arts. It was only in the 20th century that linguistics was able to break free of its sister disciplines and establish itself as an autonomous field all its own. In this talk, I first look backwards in time, in a review of the provenance and history of linguistics as a field. The idea is to take stock of where we have come from in order to get a sense for where we might be headed. Much of what we do today in linguistics has its roots in what the Sanskrit grammarians did several millennia ago.

Human cognition and behavior are highly heritable and so is liability to disorders that affect them. This includes neuropsychiatric disorders such as schizophrenia and autism spectrum disorder (ASD). We have started to integrate genetic risk data with the emerging maps of gene regulation to study human specific aspects of gene expression and gene regulation. These analyses indicate that human specific aspects of gene regulation, such as genes regulated by human specific enhancers, are indeed enriched in mutations or common genetic variants that increase risk for ASD and allied neurodevelopmental disorders. This provides evidence that genetic elements underlying human brain evolution are particularly susceptible to disruption in disease.

Africa is thought to be the ancestral homeland of all modern human populations within the past 300,000 years. It is also a region of tremendous cultural, linguistic, climatic, and genetic diversity. Despite the important role that African populations have played in human history, they remain one of the most underrepresented groups in human genomics studies. A comprehensive knowledge of patterns of variation in African genomes is critical for a deeper understanding of human genomic diversity, the identification of functionally important genetic variation, the genetic basis of adaptation to diverse environments and diets, and the origins of modern humans. We have characterized genomic variation in thousands of ethnically and geographically diverse Africans in order to reconstruct human population history and local adaptation to variable environments and have identified candidate loci that play a role in alcohol metabolism and skin color.

Our species is between 300,000 and 200,000 years old. For most of this one-quarter of a million years, up until just 12,000 years ago, it appears that our ancestors lived in small populations, in small-scale societies of which we can only guess the real nature. We remain in the dark about the age of some of the most diagnostic features of our species: our striding bipedalism, complex tool manufacture and use, fire use, language and societies defining their own identities, collaborating with and competing against neighboring societies. Data from studies of non-human animal behavior remind us of the underappreciated capacities of many other species. However, it has so far not provided evidence for any other species that shares the long list of distinctly human characteristics; chief among those, our species’ capacity to not only simultaneous modify and threaten planetary ecosystems but also document and study such ecosystems across the globe.

The first Neandertal DNA was recovered 25 years ago, and since then, ancient DNA has provided many surprising insights into human evolutionary history. Among these are the discoveries of the multiple admixture events among late Pleistocene humans and the remnants of archaic DNA in our own genomes.

In this talk, I will reflect on the findings of last quarter century of ancient DNA research about archaic humans and their environment as well as examine potential questions that the next quarter century might answer.

The discovery and resolution of genetic variation is critical to understanding disease and evolution. Our most recent work sequences diverse human and nonhuman primate genomes using both ultra-long and high-fidelity long-read sequencing technologies. Advances in this area have made possible the first telomere-to-telomere assemblies of the human genome and much more complete chimp, gorilla and orangutan genomes providing new biological insights into regions typically excluded from human genetic and comparative studies. We have discovered mega basepairs of duplicated sequence and/or rapidly evolving sequence present in humans that are absent from other non-human primates. These changes have predisposed our species to recurrent rearrangements associated with disease but also have led to the emergence of new genes important in the expansion of the human frontal cortex of the brain. Our data suggest that large-scale genome structural variation has played and continues to play a crucial role in the evolution of the human species.

Neuroscience has made great strides in the last decade following the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a science and engineering grand challenge that has greatly accelerated research on large-scale recordings from neurons and reconstructions of neural circuits. Large-scale neural network models have in turn inspired major advances in artificial intelligence. These network models have been trained on large-scale data sets to recognize objects in images, caption photographs, and translate text between languages. The most recent advance has been the emergence of pre-trained foundational language models that are self-supervised and can be adapted with fine tuning to a wide range of natural language tasks, each of which previously would have required a separate network model. This is one step closer to the extraordinary versatility of human language.

The human brain has a larger mass with respect to body weight, increased cortical neurons with respect to size, an expanded proliferative zone, and unique connectivity patterns. Human-specific neurodevelopment is not only marked by physical differences, but also by temporal changes. Human neurons, during both prenatal neurodevelopment and adult neurogenesis, exhibit an exceptionally delayed time course, a characteristic termed neoteny. Signatures of human-specific neoteny have been observed and reproduced across different systems including induced pluripotent stem cell (iPSC) and brain organoids models. We compared neurogenesis across stem cells from five primate species - rhesus, gorilla, bonobo, chimpanzee, human - and assessed the differences in transcriptional dynamics. We identified a pioneer transcription factor, GATA3, that exhibited elevated neuronal expression only in humans. This finding provides evidence for the divergence of gene regulation as a contributor to human neoteny.

Through the Earth Microbiome Program and complementary efforts, we have sampled a broad range of microbiomes from across the planet. All microbiomes that have been studied are impacted by human activity — the effects of industrialization on the human microbiome are best characterized, but capture of animals in zoos, domestication, modification of soils through agricultural practices, and modification of freshwater and marine microbiomes have also all been well characterized. Indeed, the pervasive role of environmental microbiomes in biogeochemical cycles necessary to sustain life led to a position paper entitled "Scientists’ warning to humanity: microorganisms and climate change”, the title of which speaks for itself. However, there is hope. Efforts such as the Microbiota Vault will be especially important in this respect, but also new monitoring and modeling approaches will help us understand where to look globally for the best specimens and microbes to preserve.

In 1957, the USSR launched Sputnik 1, the first human object to leave Earth. In the 65 years since then the region of Earth orbit has become filled with satellites and space junk. The proliferation of debris has led to the prediction of Kessler Syndrome, a state where a never-ending cascade of collisions between orbital objects renders parts of space unusable for human purposes. However, there are many different ways to look at the space junk surrounding Earth. For example, it is also an archaeological record of humanity’s first steps into outer space, a cultural landscape created by the combined effects of natural and cultural processes, and a technological signature of the same kind that SETI (Search for Extraterrestrial Intelligence) researchers are looking for around exoplanets in other solar systems.

We are experiencing an accelerated rate of loss of species due to human activities. This anthropogenic phenomenon extends beyond extinction. It encompasses an expanded loss of biodiversity as the genetic diversity of species diminish, reducing gene pools to “gene puddles.” We know details of species extinctions events from the fossil record, historical record, and from ancient DNA studies, and that historical processes shape extinction risk. Habitat loss and changing eco-environmental conditions, competition, and other factors produce genomic impacts, also influencing extinction risk. The legacy of past events impacts resiliency of species in the current environment in interpretable ways. Demographic trajectories reveal vulnerability to extinction. Remarkable advances in genomics technologies portend a deeper understanding of the evolution of life and the vulnerability of extant species to changes now taking place through human agency.

Humans now annually add more biologically available nitrogen to the Earth’s land surfaces than do all natural processes. For 3 billion years, available nitrogen had been the major limiting currency for life on Earth. The recent human disruption of the global nitrogen cycle is causing major environmental harm, including water and air pollution, marine dead zones, 10% of global greenhouse gas emissions, and species extinctions. Three major ways to solve this nitrogen problem are: (1) much more efficient global use of nitrogen fertilizers; (2) shifts to lower-meat and healthier diets; and (3) halting the conversion of food crops into biofuels, such as US corn ethanol used for transport.

We are losing species much more rapidly now than in the last two million years! At this pace, we may lose a large proportion of vertebrates, including mammals, birds, reptiles, amphibians, and fishes, in the next two to three decades. Modern extinctions caused by human activities are higher than the normal or natural extinction rate which tells us that we may be causing a mass extinction. In the history of life on Earth, there have been five mass extinctions – episodes where large numbers of species became extinct in a short period of time. All mass extinctions have been caused by natural catastrophes, such as the impact of a meteorite. We are the only species that has the capability to save all endangered animals. Paradoxically, saving them is the only way to save humanity. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 37904]

The introduction of species into new environments has occurred throughout human history. While most introductions fail and most of those few that establish remain environmentally innocuous, a notable minority wildly proliferates in their new ranges. These invaders disrupt ecosystems and burden economies. Environmental impacts associated with invasions are hard to predict and vary in space and time but include ecosystem-level disruptions, species extinctions, and the homogenization of biodiversity. Economic costs, while challenging to quantify, are enormous and growing. Given that established invaders are difficult to eradicate, let alone manage, stopping invasions before they start remains the most effective strategy to limit further costs resulting from invasions. Challenges to implementing this approach include regulating trade and coordinating rapid governmental responses to emerging threats.

Beginning with Homo erectus at least a million years ago, hominins have used fire to engineer the world around them. The earliest uses of fire surely included cooking, changing the energy yields of foods. Such innovations altered the course of our evolution, facilitating the evolution of species that could adapt quickly using tools and social ingenuity. Within the last 200,000 years, hominins also used fire to change the material properties of stone, pigments, sap, and wood. While these changes represent a fundamental shift in the role of humans as dominant shapers of their environments through years of evolution and innovation, ecosystems adjusted as early humans remained embedded within them. However, humans are not now simply shifting to another sustainable balance - we are pushing environmental thresholds across one tipping point after the next.

Humans have adapted to meet their water needs across disparate environments over time using behavioral adaptations. Yet, as temperatures rise and freshwater sources become depleted, it is critical to understand 1) how populations modify their environments to meet their water needs, and 2) the consequences of these anthropogenic - or human caused changes - on the environment and further on human health. This talk will provide an overview of different global water challenges and focus on a couple of case studies to highlight how development projects in remote areas that provide easier access to water, which may be high in salt or other contaminants, can unintentionally worsen health outcomes and hasten water depletion.

Because the hormones produced by our endocrine system create complex signaling networks that control our growth, maturation, fertility, immunity, behavior, and sleep, these endocrine disrupting chemicals, or EDCs, can exert powerful biological effects. Declines in human fertility evidenced by falling sperm counts and increases in the incidence of infertility raise concern that daily exposure to EDC contaminants already is impacting human fertility. By design, all species are responsive to their environment. In humans, this responsiveness means that changes in our environment can affect the production of eggs and sperm, the growth and development of the fetus, and adult susceptibility to disease. Thus, in a 21st century world characterized by environmental crises, EDCs represent a planetary health problem with the potential to affect future generations.

The world is facing a health crisis due to increasing rates of obesity and diabetes, and the consequences of this pandemic will accumulate over the coming decades. Simultaneously, climate change is accelerating and is already having devastating effects that will undermine our ability to feed the world’s growing population. In turn, our food systems contribute importantly to greenhouse gas emissions, water and land use, and multiple forms of pollution. Thus, a solution to feeding what will be about 10 billion people by 2050 diets that are both healthy and environmentally sustainable presents an opportunity to mitigate many global challenges. The EAT-Lancet commission addressed this challenge by defining healthy diets quantitatively, determining whether these can be produced within planetary boundaries for greenhouse gas emissions and other environmental factors, and identifying strategies to achieve these goals. Any solution must assume that we rapidly shift from fossil fuels to green energy. The commission found that global adoption of a flexitarian dietary pattern that could include up to about two servings per day of animal sourced foods, together with improvements in agricultural practices and reductions in food waste, would have major benefits for human health and allow us to stay within planetary boundaries. Achieving this will require the engagement of governments at all levels, civil society, and individuals.

This CARTA public symposia focuses on the long and short-term impact of humans on the planet that we inhabit, and the consequences for the future of our species. This also gives us the opportunity to celebrate the memory of the late Paul Crutzen, who coined the term “Anthropocene.” It is relevant to ask how a single species evolved the capacity to completely alter the surface of an entire planet and dominate its governing environmental and ecological processes. This symposium brings together experts regarding human impact on the planet and also addresses the current and future implications for our species.

Speakers Leslie Aiello, Michael Purugganan and Vanessa Ezenwa discuss humanity's past, present and future of the Anthropocene. Aiello speaks on how the human capacity to change the planet is not something new, but is rooted in our deep evolutionary past. One of the hallmarks of humans is our large brain size, which began to expand about 2 million years ago. Purugganan discusses how domesticated species are an interesting group of organisms that have co-evolved with Homo sapiens, and have been important in human survival and fitness. Ezenwa explores the idea that interactions between climate change and infectious diseases can increase disease prevalence in human and animal populations, but disease, in turn, may exacerbate climate change.

Speakers Mark Moffett, Charles Kennel and Martin Rees discuss humanity's past, present and future of the Anthropocene. Moffett examines the effects of the most aggressive ants on the environment, arguing that certain invasive species resemble humans in their capacity for global conquest and environmental destructiveness. Kennel speaks about the connections between past and present human exploitation of the environment, the coming crisis of the Anthropocene and what we humans can do to alleviate the crisis. Rees explores potential utopian and dystopian futures for humans on Earth. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 37934]
