Rich joins Nels and Vincent for a debriefing on the 4th Ringberg Symposium on Giant Virus Biology in Tegernsee, Germany.
Nels and Vincent look at the intracellular bacteria Legionella from an evolutionary perspective: the role of gene acquisition and reshuffling from plants, animals, fungi, and archaea in the emergence of human pathogens.
David Quammen joins Nels and Vincent to talk about his new book, A Tangled Tree, including evolutionary trees, Carl Woese, Lynn Margulis, horizontal gene transfer, and much more.
