Episode 30. Global Amphibian Declines: David Wake

Science History Podcast ·

2020/05/11

Frogs have hopped around this planet for 200 million years. In comparison, anatomically modern humans have only been around for 200 thousand years. But the last half century has seen a tragic loss in amphibian biodiversity around the world. It seems especially striking that a group of animals that predate the dinosaurs have been devastated by modern human activities. With us today to discuss the history of discoveries in the area of amphibian declines is David Wake. David graduated from Pacific

Chemistry has given the world the incredible diversity of fuels, pharmaceuticals, and household products that we rely on every day, along with tremendous advances in fighting infectious diseases and ensuring an abundant food supply. But the products of chemistry also include tens of thousands of toxic compounds that compromise human health, degrade the environment, and drive species to extinction. The advent of the modern environmental movement in the 1960s and 1970s produced a new field of

Episode 27. Biodiversity: Thomas Lovejoy

Science History Podcast ·

2020/02/11

Global biodiversity is in the midst of a mass extinction driven by rapid human population growth and over-consumption of resources. These forces drive habitat loss, pollution, invasive species, climate change, and the many other proximate causes of species losses. The study of these forces, and how they can be mitigated to preserve biodiversity, is the responsibility of scientists engaged in the field of conservation biology. My guest, Thomas Lovejoy, is a founding scientist of this field, and often

Episode 26. Linguistics: Noam Chomsky

Science History Podcast ·

2020/01/11

Nothing is more human than language, and no one has done more to advance the science of linguistics than Noam Chomsky. Noam was born in 1928, and completed undergraduate and graduate degrees at the University of Pennsylvania just after the Second World War. He earned his PhD in 1955, and by 1957, he was already publishing landmark works in linguistics that disrupted the field and fundamentally altered the understanding of language. His work also devastated the field of behaviorism, led by the likes
