Should we determine species through DNA? (part two) – podcast


In part two of The Age of Extinction takeover of Science Weekly, Patrick Greenfield and Phoebe Weston explore a relatively new and controversial technology called DNA barcoding that is helping scientists to differentiate between species – including fungi, which we heard about in part one. As the catastrophic loss of biodiversity around the world continues, could DNA barcoding at least allow us to accurately record the species that are perishing?
