Pretty good presentation on underwater archaeology. Archaeology Underwater: How Submerged Landscapes are Changing the Future of Archaeology  Archaeology Underwater: How Submerged Landscapes are Changing the Future of Archaeology presented Dr. Ashley Lemke, Assistant Professor at the University of Texas in Arlington and Chair of the Advisory Council on Underwater Archaeology The phrase “underwater archaeology” conjures notions of shipwrecks, ships lost at sea, and the dramatic catastrophes that sank them; however, the discipline can also reveal details about ancient landscapes that contain the record of past human occupations. Many of these sites are on the earth’s continental shelves where vast stretches of shallow, coastal lands were exposed at the end of the last Ice Age. These once dry landscapes supported life for plants, animals, and humans for thousands of years. In this lecture, Dr. Lemke outlines how research on submerged landscapes is becoming an increasingly important part of archaeology, focusing on a specific study in the Great Lakes, where 100 feet of water has preserved a virtually intact 9,000-year-old landscape with rooted trees, peat bogs, hunting sites, and artifacts. About Dr. Lemke: Ashley Lemke is an Assistant Professor at the University of Texas in Arlington and Chair of the Advisory Council on Underwater Archaeology. She is a leading researcher on the archaeology of hunter-gatherers. She has worked extensively on both terrestrial and underwater archaeological projects from the Lower Paleolithic in Europe to 19th-century Nunamiut archaeological sites in the arctic. She is an expert on submerged ancient sites in the Americas and has researched such sites in the Gulf of Mexico, Great Lakes, and Atlantic Ocean. Dr. Lemke received her BA from the University of Texas in Anthropology and Classical Civilizations, and her MA and PhD in Anthropology for the University of Michigan. She is the editor of Foraging in the Past: Archaeological Studies of Hunter-Gatherer Diversity, coeditor of Caribou Hunting in the Upper Great Lakes: Archaeological, Ethnographic, and Paleoenvironmental Perspectives, and author of Introduction to Archaeology: A Workbook and The Architecture of Hunting: The Built Environment of Hunter-Gatherers and its Impact on Mobility, Property, Leadership, and Labor coming soon from Texas A&M University Press. |

Another interesting presentation on some tech used by the various Indian civilizations. 14 | Prof. Michel Danino | Minor Technologies: Transport, Water-lifting, Cosmetics | 27 March 2019  14 | Prof. Michel Danino | Minor Technologies: Transport, Water-lifting, Cosmetics | 27 March 2019 Title of the talk - Minor Technologies: Transport, Water-lifting, Cosmetics, Writing, Paper, Ice-making.... While prominent traditional technologies such as metallurgy, agriculture, water management or textile, have attracted due attention, in the Indian context, “minor” technologies deserve notice, too, since their contribution was equally essential to the material growth of the civilization. This lecture briefly surveys the following technologies: sanitation (especially in the Harappan civilization); water-lifting mechanisms; transport and road networks; ship-making, sailing, and maritime trade; writing; cosmetics; earthquake-resistant construction. |

Interesting presentation on the impact of climate change to the Indus civilizations. Climate, Environment and the Indus Civilization | Prof Cameron Petrie | ASC IITGN  Climate, Environment and the Indus Civilization | Prof Cameron Petrie | ASC IITGN The ancient Indus Civilisation developed in a region marked by a two rain systems that produced a variable climate pattern and diverse environmental conditions. This presentation will consider the nature of this climatic and environmental context, and consider the ways in which they impacted on the lifeways of Indus Civilisation populations. It will also consider the degree to which the Indus Civilisation was impacted by changing climatic conditions and the degree to which populations were adapted to their environment, and resilient and sustainable in the face of changes in water availability. Bio: Cameron Petrie is Reader in South Asian and Iranian Archaeology at the University of Cambridge, and conducts research on the archaeology of India, Pakistan and Iran. He joined the Department of Archaeology in Cambridge in 2005 as the Research Councils UK Fellow in South Asian and Iranian Archaeology, and was appointed as a lecturer in 2010, senior lecturer in 2014 and reader in 2016. Prior to coming to Cambridge he was the Katherine and Leonard Woolley Junior Research Fellow at Somerville College Oxford (2003-2006), and completed his PhD at the University of Sydney in 2002. |

Interesting presentation on ratios used in building in Harappan structures. Harappan Town Planning: Unravelling its use of ratios & linear measures | Michel Danino | ASC IITGN  Harappan Town Planning: Unravelling its use of ratios & linear measures | Michel Danino | ASC IITGN Unexpectedly, almost every major Harappan structure — fortified enclosures, large buildings, reservoirs etc. — displays a simple ratio between length and breadth. This talk documents those ratios across several Harappan sites, especially Dholavira, and argues they are the result of a deliberate cultural choice — a choice that survived in later classical Indian architecture. Further, the linear units used to apply those ratios on the ground can be calculated through geometrical and statistical approaches, yielding a “master unit” of 1.9 m and a set of sub- units ending with a “Harappan angula” of 1.76 cm. This has important repercussions for the broader discipline of Indian metrology. About the Speaker: Michel Danino, Visiting Professor at IIT Gandhinagar, has authored books on Indian civilization, including The Lost River: On the Trail of the Sarasvati and Indian Culture and India’s Future, apart from many research papers on Harappan metrology and town- planning, the Sarasvati River, the Aryan debate, and cultural issues. He was a member of the Indian Council of Historical Research and is convener of a CBSE committee for the course “Knowledge Traditions and Practices of India” whose two-volume textbook he co-edited (with Prof. Kapil Kapoor). In 2017, the Government of India awarded him Padma Shri for his work on education and culture. |

Interesting overview of a Harappan city. Dholavira: A Harappan City  Dholavira: A Harappan City Dholavira in Gujarat has recently been added to UNESCO’s list of World Heritage Sites. This illustrated talk and conversation will highlight some of what makes Dholavira an outstanding example of a Harappan city. The 5,500-year-old settlement is famous for its town planning and its careful attention to water harvesting and storage, which made it possible for this bustling city to thrive for centuries in the arid environment of Kutch. To see its inhabitants through the rain-free months, the city was almost encircled with large reservoirs, which together could store several million litres of water. Unlike in many other places of historical interest, the ruins in Dholavira are not of grand palaces or large temples. Instead, we get an intimate glimpse into people’s everyday lives – the plinths of their houses are still visible, complete with courtyards, washrooms and drains. We will talk about what we know about how people in Dholavira lived and ate, who they traded with, and what they might have made, bought and sold. One of the fascinating things about the Harappan civilisation is its as-yet-undeciphered script. In Dholavira, archaeologists discovered a very intriguing and unique ‘signboard’: what might this have said? Sometime after 1800 BCE, Dholavira, and indeed, the whole Harappan Civilisation, began to fade away. Scholars believe this decline was brought about by climate change and attendant economic and social changes. |

Interesting presentation on the diet eaten by early humans in North America. New Insights into the Diet of America's First Peoples, Dr James Chatters  New Insights into the Diet of America's First Peoples, Dr James Chatters In recent decades archaeologists have actively, often acrimoniously debated the migration route and ecological adaptation of the earliest Americans. You have the Kelp Highway hypothesis, that argues for a maritime adaptation versus the inland migration hypothesis that envisions of terrestrial foragers. Then, for Clovis, the first and only continent-wide cultural pattern, we have those who see big-game focused adaptation versus backers of the “broad spectrum forager” hypothesis. Recent studies of two of the most ancient human skeletons, the Anzick boy and Naia of Hoyo Negro contribute actual, direct evidence to these debates (see maps below). Each allows us to approach the question from a different perspective. The Anzick boy’s bone proteins were well preserved, so it was possible to conduct a stable isotope analysis to the determine most likely diet of this nursing toddler’s mother. Naia’s bones lacked protein but were nearly complete, enabling an analysis of her growth patterns, supported by isotopes in her bone minerals. Both sets of results identify megafauna as central to the diet of these earliest Americans. They present these early immigrants to our hemisphere as highly sophisticated mobile who subsisted by following the most mobile, wide-ranging prey. That, in turn, light on Clovis culture could have spread so rapidly throughout North and South America and could have contributed to the extinction of native megafauna. |
