Talk by Vivian Ash
Ever since Darwin, a branching tree has been the model for the evolution of life on Earth with genes passed vertically from parents to offspring. However, the discovery of horizontal gene transfer has threatened this idea. Has the tree of life been cut down or will it live on as the primary paradigm of life on our planet?
