Humans are a spectacular outlier among the millions of species of life on planet earth, with incredibly unique biological success. Slowly, scientists have begun to understand the traits that interacted to make us unique, such as cumulative culture, unique scales of cooperation, cognitive abilities, language, and a unique life history and mating system. However, the sequence of evolutionary events that led to our unique species was very much a mystery until the discovery of early bipedal hominins like the australopithecine, Lucy. Here, Kim Hill explains how we have learned so much about this improbable sequence and evolutionary pathway by discovering that early hominins were fully bipedal but still had small brains and little evidence for human mating and life history patterns or cumulative cultural evolution. Lucy helped us understand why the evolution of bipedality was a critical first step that led to an amazing evolutionary sequence that resulted in our spectacular outlier species.

The connection between paleoanthropology and primatology began with Darwin's theory of human origins. Lucy's discovery challenged existing ideas, coinciding with observations of wild primates. This sparked a surge of research on primate behavior, enriching our understanding of human evolution. Despite behavior not fossilizing, studying living primates has deepened insights into ancestral lifestyles. By examining their social and ecological dynamics, researchers unravel the origins of complex behaviors like cooperation and culture, shedding light on human adaptations. This interdisciplinary approach has refined methods for studying social processes and their biological effects. Fifty years since Lucy's find, these tools continue to shape our understanding of human evolution and its relevance today.

The discovery of Lucy, a fossil from the 1970s, changed paleoanthropology. Before Lucy, scientists saw human ancestors as rough guides, not distinct species. This mindset dominated the interpretation of fossils. Lucy's discovery, representing a new species called Australopithecus afarensis, showed the need to define species clearly. The clash of old and new views was seen in a 1981 debate between Richard Leakey and Donald Johanson. Leakey's refusal to offer an alternative emphasized flaws in traditional practices. This marked a shift towards a better understanding of human origins and diversity, despite some scientists holding onto old ways.

UC San Diego professor Carol Marchetto discusses how a comparative gene expression analysis of human and non-human primates revealed differences in the regulation of a class of transposable elements LINE1 retrotransposons between species. University of Southern California professor Joseph Hacia discusses studies profiling phytanic acid levels in red blood cells obtained from humans and captive non-human primates all on low phytanic acid diets. Emory University professor James Rilling discusses the difference of arcuate fasciculus between human and non-human primate brains and how the specialization of speech has helped humans evolve.

This symposium addresses several important distinctly human characteristics that range from molecules, to metabolism, anatomy, disease, and behavior. Goals include transdisciplinary interactions, improved self-understanding, promotion of ethically sound studies to explain known differences, and the generation of new, potentially unexplored, insights on uniquely-human specializations. Given the interest in understanding our evolution, this symposium will also help to organize how and in what sequence distinctly human physical, mental, social, and cultural features evolved. Such understanding may help explain the origin of our species and how it came to now directly shape the planet, giving rise to the Anthropocene (a proposed geological epoch distinguished by human influence on climate and the environment).

Identifying cellular and molecular differences between human and non-human primates is essential to the basic understanding of the evolution and diversity of our own species. While preserved tissues are the main source of comparative studies between humans, chimpanzees and bonboos, the samples do not accurately represent the traits of live cell behavior and cannot be genetically manipulated. UC San Diego professor Carol Marchetto discusses how a comparative gene expression analysis of human and non-human primates revealed differences in the regulation of a class of transposable elements (Long Interspersed Nuclear Element 1 or LINE1 retrotransposons) between species.

Unlike our closest primate relatives, chimpanzees and bonobos, humans form strong intergroup ties which can mitigate coalitionary aggression and make peace possible. However, such bonds can also be used to build larger alliances that take such conflicts to a new level of magnitude, supported by cultural and linguistic proficiencies. Arizona State University and University of Utah professor Polly Wiessner addresses intergroup ties between humans, chimpanzees and bonobos, explores some of the possible evolutionary developments that contributed to the human disposition to form mutually supportive external bonds, and then discusses the impact of social ties on coalitionary action.

Emory University professor Dietrich Stout discusses an evolutionarily motivated definition of technology that highlights three key features: material production, social collaboration, and cultural reproduction; UC San Diego professor Pascal Gagneux discusses how recent comparative genome studies have revealed that this polymorphic system is ancient and shared between humans and non-human primates, this despite the fact that none of the great ape species carries all four ABO blood types; and University of Utah professor James O’Connell discusses food sharing, evaluates one hypothesis that focuses on males acquiring big game meat and marrow to provide for mates and offspring. The other hypothesis surrounds how certain kinds of savanna plant food set up the forager interdependence which propelled all aspects of life history change.

Technology is clearly central to human life and evolution but remains hard to define and study. Emory University professor Dietrich Stout discusses an evolutionarily motivated definition of technology that highlights three key features: material production, social collaboration, and cultural reproduction. This perspective has important implications for the way we conceptualize and study the origins and evolution of human technologies.

Humans and many other species have biologically endowed abilities for discriminating “quantities” to some degree (e.g., subitizing), but only humans, via the distinct capacity of “symbolic reference” exhibit “number” — i.e., exact symbolic quantification. Language, with its symbolic properties although present in all human cultures, is a necessary condition for “number” but it is not a sufficient condition for it. UC San Diego professor Rafael Nuñez discusses the comparative analysis of “quantity” and “number”, and the implications it has for debates about the origins of other human special capacities such as geometry, music, and art.

Sialic acid-recognizing immunoglobulin-type lectins (Siglecs) are a family of cell surface proteins prominently expressed on immune cells in mammals. Siglec-11 is an example of an inhibitory Siglec. It was the first protein in the brain found to be “human-specific”: non-human primates express Siglec-11 in other tissues but not in the central nervous system. UC San Diego School of Medicine professor Ajit Varki discusses the importance of Siglec-11 and the paired receptor Siglec-16, and how they play significant roles in regulating inflammation, and have several uniquely human features including expression in brain.

Since entering into the field of paleoanthropology in 1970, Donald Johanson has found a more focused and rigorous implementation of an expanded collaborative, multinational, transdisciplinary strategy of inquiry with the application of new theoretical and technical innovations that has resulted in a richer picture of our origins and a deeper understanding of how we became human—not only in Africa, but Eurasia as well. The discovery of Lucy 50 years ago provides an appropriate benchmark by which to contrast what we know in 2024 versus what we thought we knew prior to her discovery in 1974. Knowledge of the environment in which our ancestors lived and interacted and successfully navigated the challenges of survival is now coming into clearer focus. We are in a period of specialization, and it is imperative to embrace an integrated approach that melds biological and cultural evolution. Only in this way can we continue to provide a more far-reaching vision of our ancestry.

During embryogenesis, the three germ layers (endoderm, ectoderm, mesoderm) differentiate into epithelial and non-epithelial cells, which eventually form differentiated tissues and organs. Abundant data now indicates that we humans are very closely related to other hominids including chimpanzees, bonobos, gorillas, and orangutans, the so-called "great apes". UC San Diego School of Medicine professor Nissi Varki discusses the incidence of carcinomas, including the rarity of occurrence of common human carcinomas in captive chimpanzees.

Diet has played a major role in the evolution of human and non-human primate digestive systems. Phytanic acid is a potentially toxic branched chain fatty acid that can be acquired in humans by ingesting plant and/or animal products. Although it was established that humans cannot derive phytanic acid from chlorophyll and instead normally obtain it only from meat, dairy, and fish products, less was known about the capacity of non-human primates with proportionally larger hindguts to obtain phytanic acid from plant materials. University of Southern California professor Joseph Hacia discusses studies profiling phytanic acid levels in red blood cells obtained from humans and captive non-human primates all on low phytanic acid diets. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 37379]

ABO Blood groups represent the first described human molecular polymorphism. The ABO gene encodes variants of a protein (a glycosyltransferase) that produces the short sugar chains on glycoproteins and glycolipids that define the A, B, or O antigens. These antigens are found on red blood cells, plasma glycoproteins, and other cell types in various tissues. Individual humans can have one of four blood types based on the two alleles inherited from both parents at the ABO locus: blood type A, B, AB, or O. UC San Diego professor Pascal Gagneux discusses how recent comparative genome studies have revealed that this polymorphic system is ancient and shared between humans and non-human primates, this despite the fact that none of the great ape species carries all four ABO blood types.

Humans are unusual in that we depend on shared foods, especially among families and friends and between potential mates. Food sharing occurs between healthy individuals and those that are infirm or elderly. We also differ from other great apes in our early ages at weaning, late ages at maturity, short birth intervals and survivorship decades past menopause. The emergence of these patterns was crucial to early human development. In light of observations among modern East African hunter-gatherers, University of Utah professor James O’Connell evaluates two alternatives. He discusses one hypothesis that focuses on males acquiring big game meat and marrow to provide for mates and offspring. The other hypothesis surrounds how certain kinds of savanna plant food set up the forager interdependence which propelled all aspects of life history change.

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.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? David Carrier proposes anatomical adaptations for aggression. A growing body of evidence suggests that the evolutionary roots of much of the aggression, intolerance, and violence that plagues modern societies ultimately lies in the selection that shaped our mating system. Acknowledging and understanding the legacy of male interpersonal and group aggression can help guide policy directed at reducing violence in the future.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Jandy Hanna explores climbing in human evolution. Most primates live and move in the trees, but humans have evolved to move bipedally on the ground. Primates’ arboreal life-style has long been thought to have allowed the evolution of human beings’ unusual form of movement. We know much about how horizontal movement on branches differs in primates relative to most other mammals. But only recently have we begun to learn about how climbing is accomplished by non-human primates, and how such movement may have permitted early human ancestors to move upright. Key findings regarding the biomechanics of climbing, and what these data may mean for understanding human movement and exercise, are discussed.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Grazyna Jasienska discusses different effects of activity on women's reproductive health. The effects of physical activity on female physiology and health are much more complex than for men. Just like in men, activity is beneficial for many aspects of health, but physically active women also face important physiological trade-offs. Physical activity influences levels of hormones that are crucial for female health – estrogens and progesterone. But how much and in what way these hormones are affected depends not only on the type and intensity of physical activity, but also on other factors, such as the quality of environment that women experienced during their own fetal development and childhood.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Daniel Lieberman explores how running evolved and its role in human evolution. All animals need to be physically active, but the human lineage clearly underwent selection to be considerably more physically active than our relatively inactive ape ancestors and cousins including chimpanzees and gorillas. Bipedal walking brought many benefits but also rendered hominins slow and awkward, hence vulnerable to predation. With the origins of hunting and gathering in the genus Homo, there was additional selection for endurance running which helped hominins become scavengers and hunters. Today we face a growing epidemic of physical inactivity that increases people’s vulnerability to a wide range of diseases.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Herman Pontzer explores the evolution of human metabolism and its role in our evolution and health. From an evolutionary perspective, life is a game of turning energy into offspring. The strategies that species use to acquire energy, in the form of food, and allocate energy to the essential tasks of growth, maintenance, movement, and reproduction, are incredibly diverse and reflect the ecological pressures and opportunities encountered. There is a deep evolutionary history of the human metabolic strategy and our divergence from other apes.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? David Raichlen explains the effects of physical activity on the brain and its role in evolution. Recent work suggests exercise can have important beneficial effects on the aging brain, however the underlying mechanisms remain poorly understood. An evolutionary-neuroscience approach may help us better understand these mechanisms and can provide a foundation for developing novel interventions to improve brain aging.

Human physical activities differ significantly from other species. Although hunter-gatherers sometimes climb and fight, they also walk and run long distances as well as dig, throw, carry and more. How, when and why did these capabilities evolve? What genetic, physiological and anatomical adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics such as the brains, diet, life-history strategies, gene-culture co-evolution and social cooperation? To address these and other related questions, this symposium will integrate research on genetics, biomechanics, physiology, neurobiology and behavior. Because more and more humans today are primarily sedentary, we will also explore implications of the evolution of human physical activity for contemporary health and disease.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Yana Kamberov explores how sweating evolved and what it means for Homo sapiens. Humans use sweating as the primary mechanism to dump body heat. Humans’ ability to effectively harness sweating as a thermoregulatory mechanism is a product of the evolution of a massively increased sweat gland density and a drastic reduction in the size of body hair. Advances have been made in identifying the genetic basis for how these unique and essential adaptations of human physiology evolved.

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.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Tatum Simonson explains adaptations to altitude and diving. Humans have persisted for hundreds of generations under challenging environmental extremes. Adaptations to such environments have been essential for survival, enabling populations to trek successfully among high mountain tops or to dive deeply into vast seas. Unique genetic signatures, resulting from thousands of years of strong selective pressures in these environments, have been discovered within the DNA of present-day populations. These findings provide important clues into evolutionary processes in humans. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Science] [Show ID: 36946]

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.
