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 environmental impact habitation, complex social organization systems anchored within constructed sacred...

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 individual learning. Some changes came about through social interactions in a process called energized...

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 biological evolution yield humans with the “construction-ready brains” and bodies that made us capable of...

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 site in Zambia preserves rare evidence for the shaping and fitting together of two tree trunks to...

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 factors from landscape to culture and the construction of history embodied in it - and more. After...

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 nonhuman primates lack interesting building skills, and so we suggest that bird nest construction may...

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 of Australia.” Architecture has been shaped in every era by our access to energy, from fire to...

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-resident communities became common in the Holocene. The Neolithic (9600-6000 BCE) saw major social,...

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...

Paleoanthropology is booming with discoveries, reshaping our understanding of human evolution. Lucy's 1974 find stands as a milestone, providing crucial insights into early hominins. Her species, Australopithecus afarensis, remains a key reference, revealing bipedalism and dietary adaptations. Recent findings suggest bipedality evolved from arboreal upright apes, not chimpanzee-like ancestors. Earlier australopiths show bipedality predates dietary changes, indicating walking aided dietary...

The savanna hypothesis suggests that early human ancestors evolved in open grasslands. Raymond Dart's 1925 discovery of Australopithecus africanus at Taung supported this idea. Lucy's 1974 discovery confirmed bipedalism in Australopithecus species but raised questions about their tree-dwelling habits. Studies since then have refined our understanding of ancient habitats and climates, showing that human evolution involved interactions with various environments, not just savannas. This requires...

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...
