The Evolution of Bacteria

This episode is with Michael Levin and Nick Lane. Mike is a Professor in the Biology department at Tufts University. He studies the role of bioelectric signals in regulating development and regeneration in animals. Nick is a professor of Evolutionary Biochemistry at University College London. His work is focused on the fundamental processes that underlie the origin and evolution of life. In this conversation, we talk about major transitions and key innovations in biology, information in biological systems, bioelectricity, emergence of eukaryotes and importance of bioelectric signals to create artificial life.
