“The Human Journey From Ape to Agriculture” with Professor Peter Bellwood

Over a span of five million years, humankind rose from modest origins to become the planet’s most dominant species. Along the way, people changed a lot in how they looked, spoke, and lived. But how did all this happen? The variety we see in humans today is the result of evolution—which began shaping the Homo group about 2.5 million years ago—and migration, as humans moved into new places. In his book “The Five-Million-Year Odyssey: The Human Journey from Ape to Agriculture” Professor Peter Bellwood brings together research from archaeology, biology, anthropology, and language studies to tell the story of human history. He takes us from the earliest hominins in Africa, through the spread of humans across the continents, to the start of farming and rapid population growth. He introduces early human relatives like the australopithecines, Homo erectus, and Neanderthals, then focuses on the rise of Homo sapiens about 300,000 years ago and their journey into Eurasia, Australia, and the Americas. Bellwood also looks at how farming, which began around 10,000 years ago, helped people move to new lands and share their languages and cultures. In this episode of Bridging the Gaps, I speak with Professor Peter Bellwood.

Peter Bellwood is professor emeritus at the Australian National University. He specialises in the human population prehistory from archaeological, linguistic and biological perspectives. His many books include “First Migrants: Ancient Migration in Global Perspective” and “First Farmers: The Origins of Agricultural Societies. He is the winner of the 2021 International Cosmos Prize.

We begin by discussing how studying languages uncovers our past and tells the story of humans. Language families act like maps, pointing to early journeys of people. Shared words that appear in many tongues offer strong clues about those first moves. Next we look at what ancient DNA and proteins can say about our past. I first ask about the hard job of finding and testing old genetic samples. After that we turn to classic archaeology, and I ask Peter about digging at historic sites. We dive into how a creature unlike any other animal arose, and we touch upon the blank spots that still puzzle us. The book’s idea of “man the tool maker” comes up: does making tools really set us apart? We talk about that in depth.

We then explore the rise and later disappearance of Neanderthals and other early human groups. Our focus shifts to the cultural growth of Homo sapiens, tracing the path from hunting and gathering to more organised farming. We look closely at the first waves of people who moved in search of richer soil and safer homes. The Fertile Crescent in the Middle East gets special attention, as we track the birth of stable villages and maybe the first cities. We also discuss the boats, paths, and simple gear that helped early travellers to travel long distances.

Shifting dates and fresh finds force us to keep revising the human timeline. We talk about lively cultures that either vanished overnight or slowly faded away. From start to end, the talk has been rich, clear, and full of insights.

“Ending Epidemics: A History of Escape from Contagion” with Richard Conniff

Ending Epidemics on Bridging the Gaps pocast

It is difficult to imagine a not-so-distant past when deadly diseases were a routine part of life. Even more astonishing is the fact that during that time, prevailing medical beliefs attributed these diseases to harmful miasmas, bodily humors, and divine dyspepsia. However, a groundbreaking revelation occurred with the discovery of the world of microorganisms, which led to the understanding that these tiny organisms might be responsible for transmitting and spreading diseases. These pivotal discoveries and understandings paved the way for numerous measures and techniques to prevent the transmission of infectious diseases.

The history of epidemics and humanity’s progress in combating these diseases is full of captivating stories. In his new book, “Ending Epidemics: A History of Escape from Contagion,” prolific author Richard Conniff outlines how our comprehension and prevention of some of the most devastating infectious diseases have advanced, consequently doubling the average life expectancy. In this episode of Bridging the Gaps, I speak with Richard Conniff, delving into moments of inspiration and innovation, decades marked by unwavering determination, and periods of profound suffering that have spurred individuals, institutions, and governments to take action in the pursuit of public health.

Richard Conniff is a prolific author of several non-fiction books and many articles for magazines such as National Geographic, Smithsonian, and Time. He is a contributing opinion writer for the New York Times, and a former commentator on NPR’s “All Things Considered”. He has won the National Magazine Award. He has also written and presented nature programmes for National Geographic television, the Discovery channel and the BBC.

Our conversation begins with an exploration of how communities in old days grappled with epidemics, given their limited understanding of the causes behind such widespread outbreaks. We delve into the intricate ways in which communities tried to comprehend and interpret illnesses before the pivotal discoveries of microorganisms and germs. An engaging segment follows, chronicling the efforts of early pioneers who harnessed the power of microscopes to identify microorganisms believed to be responsible for various diseases.

One captivating narrative we explore revolves around the remarkable utilization of cowpox to foster immunity against smallpox—an extraordinary breakthrough in the history of medicine. However, we also address the resistance encountered by these novel ideas and concepts. We then delve into the emergence of the concept of immunity, the discovery of microorganisms, and the subsequent development of vaccines and antibiotics. Additionally, we discuss the profound realization that improved sanitary conditions are indispensable for safeguarding public health.

Naturally, our conversation turns towards the recent Covid-19 epidemic, examining humanity’s response to this global crisis. Richard offers a significant insight that despite our enhanced capabilities in dealing with epidemics, these formidable diseases persist and may pose future threats if we fail to remain vigilant to the dangers they present.

“Kendall Square and the Making of a Global Innovation Hub” with Robert Buderi

Where Futures Converge on Bridging the Gaps podcast

Kendall Square, situated in Cambridge, Massachusetts, has earned the reputation of being “the most innovative square mile on the planet.” It serves as a vibrant epicentre for life sciences, housing renowned companies such as Biogen, Moderna, Pfizer, Takeda, and many others. Additionally, it stands as a prominent hub for technology, with giants like Google, Microsoft, IBM, Amazon, Facebook, and Apple occupying substantial portions of valuable office space within its bounds. The square is also home to a thriving community of startups, with convenient proximity to leading venture capital firms. Moreover, its proximity to Massachusetts Institute of Technology (MIT) further enhances its status as a centre for cutting-edge ideas.

In his book “Where Futures Converge: Kendall Square and the Making of a Global Innovation Hub,” Robert Buderi shares interesting accounts of visionary innovators and their groundbreaking creations, spanning a remarkable two centuries. In this episode of Bridging the Gaps, I speak with Robert Buderi, exploring the distinctive ecosystem that defines Kendall Square. We discuss various cycles of transformation and reinvention that have propelled its evolution over time.

Robert Buderi is an author, journalist, and entrepreneur. He is the author of “Engines of Tomorrow, The Invention That Changed the World”, and other books. He is former Editor-in-Chief of “Technology Review”, and founder of the media company Xconomy.

We begin our conversation by talking about Kendall Square’s geography, which means where it’s located, and its history as a place known for business and innovation. We then take a closer look at the first innovators who chose Kendall Square to start their businesses and create new products and services. We also talk about the advantages of having important academic and research institutions close by and explore the relationship between industry and academia. After that, we shift our focus to the present and talk about what Kendall Square is like today. We explore the different industries, products, and services that are based there. Overall, this is an interesting and informative discussion.
