For thousands of years, scholars have struggled with what it means to be human. One critical dimension of humanity is foresight, and with us to decipher the evolution of foresight is Thomas Suddendorf. Thomas is a professor at the University of Queensland, where he investigates mental capacities in young children and in animals to answer fundamenta…

Johan Rockström and colleagues first proposed the concept in 2009 of planetary boundary threats and a safe operating space for humanity. This conceptual framework clarifies environmental problems that are of planetary significance, such as biodiversity loss, climate change, and stratospheric ozone depletion. The most recently articulated planetary…

The Wall Street Crash of 1929 and the ensuing worldwide Great Depression left families in economic shock and despair. International trade collapsed to less than half of its previous levels and unemployment skyrocketed. Into this devastating mess stepped Franklin Delano Roosevelt, who began his long presidency in 1933. FDR spearheaded a series of pr…

The ways people think about matters both big and small, from climate change to daily tasks, impact the outcomes. Throughout the history of science and society, key insights arose through a thought process of simplification and subtraction, though the human tendency leans towards complication and addition. Today I discuss the power of subtraction wi…

No matter our claims to the contrary, we are all biased in our perceptions and beliefs. But bias is not random and its directions relate to our evolutionary history and culture, especially to how these interface with human sociality. With us to decipher bias is Jim Zimring. Jim is the author of What Science is and How it Really Works, published by …

The oceans have been used as the dumping grounds for all manner of toxic waste. Outrage over such dumping led to the Marine Protection, Research, and Sanctuaries Act of 1972 in the United States and the London Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter in 1975. Today I discuss the dumping of DDT and other…

Many landmarks of environmental history share a connection with a single molecule: DDT. During and after the Second World War, it was broadcast into the environment at a scale that far surpassed the applications of any prior chemical. The public met this mass spraying of DDT with enthusiasm, as the war proved it to be highly effective against the v…

In this episode, we explore five strange fossilized footprints found by Mary Leakey at the site of Laetoli in Tanzania. Decades after their original discovery, these footprints have revealed a new story about our ancient ancestors that expands our understanding of how hominins moved and interacted. ThanksThanks to Dr. Ellison McNutt and Dr. Charles…

At the start of the 20th century, physicists probed the structure of nature. Their discoveries changed our fundamental understanding of matter, of life, and of war. At the center of these discoveries stood the Danish physicist Niels Bohr. Bohr approached problems of atomic structure and quantum theory with a philosophical perspective and an ability…

The advent of agriculture over 10,000 years ago forever altered the trajectory of humanity. Communities grew larger until cities and nations dotted the landscape, labor became specialized, new diseases emerged, civilizations flourished and vanished, warfare increased in scale and lethality, and people colonized every corner of the globe. Agricultur…

The brain is the most mysterious and complex organ of the body, and when things go awry, we may be confronted with personal tragedy and we may gain insights on what it means to be human. With us to discuss neurological disorders and the history of their discovery is Sara Manning Peskin. Sara completed an AB in biochemistry at Harvard University in …

In this episode, we talk with Evan Hadingham, senior science editor for the PBS program NOVA. His new book, Discovering Us: 50 Great Discoveries in Human Origins, highlights the thrilling fossil finds, groundbreaking primate behavior observations, and important scientific work of Leakey Foundation researchers.

Nothing is so intertwined with human success and folly as economics. The economy, for better or for worse, drives much of our fate from our household budget to our national policies to the outbreak of war. But economic activity also has profound effects on the environment and a close inspection of economics opens the question of whether humans can …

The 60s hosted the space race between the United States and the Soviet Union, which occurred in the midst of the Vietnam War, the Cold War, and civil unrest. How did the culture wars of the 1960s relate to the space race, especially in the United States? How did the Civil Rights Movement, the New Left, environmentalism, the women’s movement, and th…

As a young girl, Biruté Mary Galdikas dreamed of going to the forests of Southeast Asia to study the least-known of all the great apes, the elusive orangutan. People told her it would be impossible. But, in 1971, she traveled to Borneo and started what is now the longest ongoing study of orangutans in the history of science. This is her story. She …

How do we distinguish real science from hogwash? How does real science evolve over time into pseudoscience? Why will science always be plagued with sister movements on the fringe that make us cringe? With us to explore these topics and their relationship to the demarcation problem is Michael Gordin. Michael is the Rosengarten Professor of Modern an…
