CARTA - Anthropogeny (Audio)

Human beings show a range of emotional attachment, affection, and infatuation often referred to as “love”. Love promotes long-lasting and secure relationships that involve nurturing and support. Biological mechanisms underlying such behavior involve ancient neuropeptides and their receptors in the brain. These systems are also involved in reproduction, ranging from mating and pair-bonding, to givi...

Human fathers exhibit hormonal shifts in testosterone, prolactin, and oxytocin, enabling flexible responses to parenting. In species with costly paternal care, these shifts balance mating and parenting efforts, suggesting evolved neuroendocrine capacities that support fatherhood. Today, fathers collaborate with mothers worldwide, though their roles vary across cultures and family systems, much as...

The titi and owl monkeys of South America live in socially-monogamous groups where the male and female establish a pair bond and share parental duties. Why do males of these species mate in a monogamous relationship presumably foregoing other reproductive opportunities? And why are titi and owl monkey males such good fathers, investing heavily in the care of offspring that they cannot be certain t...

Grandmothers play a key role as alloparents in human families. A leading hypothesis suggests that the inclusive fitness benefits of grandmaternal care selected for an extended female lifespan after reproduction, a unique trait among primates. Beyond lifespan extension, grandmothers may have biological adaptations for caregiving. Research from our lab shows grandmothers have lower DNA methylation o...

Close relationships help us shape both our other social interactions as well as our internal physiology. Do these close relationships, also known as pair bonds, look and function similarly in species as diverse as titi monkeys, prairie voles, seahorses, and humans? How do negative experiences such as loss factor into, and perhaps strengthen, our close relationships? And what do we mean by luminanc...

Dr. Theofanopoulou studies neural circuits behind sensory-motor behaviors like speech and dance, aiming to develop drug- and arts-based therapies for brain disorders. Her brain imaging research reveals overlapping motor cortex regions controlling muscles for speech and dance, while transcriptomic studies show upregulation of the oxytocin gene pathway in key areas like the motor cortex and brainste...

Humans are an intensely social species. We experience social interactions as rewarding from infancy, and the social cognitive skills that we develop in the context of our earliest interpersonal attachments are critical for our survival and personal well being. Lack of social connection is common in many psychiatric and neurodevelopmental disorders. In some disorders, like autism spectrum disorder,...

Oxytocin is a peptide molecule with a multitude of physiological and behavioral functions. Based on its association with reproduction, including social bonding, sexual behavior, birth and maternal behavior, oxytocin also has been called “the love hormone.” This presentation will examine parallels between the healing power of oxytocin and love. As described here, many myths and gaps in knowledge re...

Ancient texts warn of love turning into hatred, as seen in stories like Cain and Abel or “Et tu, Brute?” This talk explores the neurobiology of hatred based on the biology of love: the oxytocin system, attachment networks, and biobehavioral synchrony, which mature through mother-infant bonding and later support group solidarity and out-group hostility. Using this model, we developed Tools of Dialo...

At a global level, Homo sapiens have reshaped the planet Earth to such an extent that we now talk of a new geological age, the Anthropocene. But each of us shapes our own worlds, physically, symbolically, and in the worlds of imagination. This symposium focuses especially on one form of construction, the construction of buildings, while stressing that such construction is ever shaped by diverse fa...

The symbolic tools we use to design and construct our environments have been transformed by the so-called Cybernetic revolution and the innovations in materials technology that have accompanied them. The integration of computers, the Internet of Things, embedded robotics, and artificial intelligence (AI) supports the development of intelligent/smart buildings where specific levels of automation ca...

The site of Göbekli Tepe is well known as a settlement of the transitional phase in SW-Asia, in which the greater mobility of the Palaeolithic increasingly gave way to the more permanent settlement of the Neolithic. This talk uses the example of Göbekli Tepe to explore the linkage of buildings with ecology, climate, economy, cultural, political, symbolic systems, and creation of networks between d...

This presentation will briefly trace 70,000 years of cultural evolution from the ancient crossing from Sunda to Sahul, via the swift continental colonization during the Ice Age, through the severe impacts on survival during the Last Glacial Maximum, and the socio-territorial reconfigurations during Holocene sea-level rise. The Australian Aboriginal world had become characterized by low environment...

The transition from Neolithic villages to early cities marked the greatest social transformation faced by our species before the Industrial Revolution. Our ancestors had to learn how to live in new settlements that had more people, higher densities, and more activities than had been known previously. The new adaptations to urban life involved changes in society and social processes, not just indiv...

Humans construct their physical worlds in part by designing and constructing new tools, habitations, and in due course diverse buildings and, in some cases, towns and cities and construct their symbolic worlds by putting words together to tell stories, articulate plans, tell lies, seek truth, and much more. This talk offers hypotheses that address a key question for anthropogeny: How did biologica...

This talk provides a deep time perspective for assessing the behavioural implications of the creation of the earliest known structure and the technologies used in its making. Evidence for the earliest structure appears relatively late, about 500,000 years ago in Zambia, and before the evolution of Homo sapiens. The next oldest structures were made by Neanderthals in Europe, 176,000 years ago. The...

As distinct from the buildings of termites (interesting though these are), bird nests offer a more apropos point of comparison for human buildings – they are conducted by single vertebrate (or a few) and can be adapted to varied circumstances, with even a small effect of social learning. However, the basic Bauplan remains species-specific, unlike the creativity of the human architect. Since nonhum...

Every building – from the Parthenon to the Great Mosque of Damascus to a typical Georgian house – was influenced by the energy available to its architects. This talk offers a historical perspective on a topic of great relevance today, the linkage of architecture and energy. It provides a useful complement to the non-urban perspective on ecology offered by the talk on “The indigenous architecture o...

Human "place-making" began over a million years ago when early humans made the hearth the center of social life. By 450,000 years ago, they were using caves in southwest Asia and sometimes buried their dead beneath the floor, linking memory-making with place-making. Hunter-gatherers started settling seasonally around 24,000 years ago, with permanent stone settlements by 13,000 BCE. Large, co-resid...

Lucy is one of the most famous fossils of all time. The discovery of this species had a major impact on the science of human origins and evolution. Why? What was that impact? The symposium speakers—each a prominent scientist in their field—will address this question and specifically discuss the discovery’s impact through time, starting with the first few years after the discovery, the lasting impa...

The discovery of a 3.2-million-year-old hominin skeleton named Lucy revolutionized human evolutionary studies. Her Linnean classification as Australopithecus afarensis sparked debates on taxonomy, highlighting the complexity of interpreting fossil evidence and shaping our understanding of hominin evolution. Lucy's systematics provide insights into the challenges of classifying early hominins, emph...

Lucy, discovered in 1974, revolutionized paleoanthropology, sparking interest in Africa's fossil-rich regions. This led to significant discoveries, pushing human origins records beyond six million years. Lucy's find prompted the establishment of research facilities in Africa, aiding local scholars' training. As we mark her 50th anniversary, we celebrate scientific progress and African research inf...

Lucy's 50-year legacy as a superstar in human evolution is undeniable. Yet, with newer, older fossils and a growing understanding of her ancient world, her status as our ancestor is questioned. This talk delves into how these discoveries reshape Lucy's narrative and our understanding of human evolution, likening her to a middle-aged celebrity facing new challengers.
