Archaea

Archaea

Author: BBC April 9, 2026 Duration: 54:53
Misha Glenny and guests discuss one of the most remarkable scientific discoveries of the 20th century: the archaea microorganisms. In the 1970s the American microbiologist Carl Woese (1928-2012) realised that the tiny bacteria-sized organisms he was studying were not actually bacteria but from an entirely different branch of the tree of life. It became clear that archaea, as he named them, share aspects of the cells in all plants and animals even if they often live in places where other life struggles including salty lakes, acidic pools, under the sea bed and in the gut. While aspects of what followed from Woese are still under debate, further discoveries suggest that life on Earth has been on a journey of separation and reunion: that the first cells developed into bacteria and archaea billions of years ago and that some of those later combined to form the complex cells from which we are made.

For decades, Melvyn Bragg has convened some of the world's sharpest minds around a single, unassuming table, and the resulting conversations form the heart of In Our Time With Melvyn Bragg. This BBC podcast is less a formal lecture and more an eavesdropped dialogue, where complex ideas from religion, philosophy, science, and history are unpacked with genuine curiosity and clarity. Each episode focuses on a single concept, event, or figure-from the intricacies of Islamic philosophy to the paradoxes of quantum mechanics, from the rise of the novel to the fall of ancient empires. Listeners are brought directly into a thoughtful, often lively discussion where experts debate, clarify, and connect the dots, guided by Bragg's probing yet generous questioning. You'll hear the context and contradictions behind the ideas that have shaped our spiritual and intellectual landscape, presented not as dry facts but as living, debated history. The enduring appeal of this podcast lies in its depth and accessibility, transforming daunting subjects into compelling narratives. It’s a weekly invitation to step back from the noise and spend forty-five minutes engaged in the kind of substantive, ad-free conversation that reminds us of the profound connections between all fields of human thought.
