TB vaccination to replace culling in badgers; Neil Shubin on the wonders of evolution

The government have announced that the controversial cull of badgers across England will begin to be phased out in the next few years. It will be replaced by vaccinating badgers for bovine TB. The cull is intended to cut tuberculosis in cattle and has killed at least 100,000 badgers since 2013. TB in cattle is a severe problem for farmers and taxpayers, leading to the compulsory slaughter of 30,000 cattle and a cost of £150m every year. However culling is thought to have failed because frequent trading of cattle and poor biosecurity on farms severely hampering efforts to tackle the crisis. Expert and ecologist Rosie Woodroffe at the Institute of Zoology, the research division of the Zoological Society of London, who has been trialling vaccinations for the past few years in Cornwall explains to Marnie Chesterton why it is highly desirable to move from culling to vaccination of badgers. Plus they discuss the parallels between this and the coronavirus outbreak in humans. Evolutionary biologist Neil Shubin at the University of Chicago, is also the author of the best-selling book on evolution – ‘Your Inner Fish’. In his new book, out this week, ‘Some Assembly Required – Decoding four billion years of life from ancient fossils to DNA’, Neil revisits the topic of evolutionary development and explains to Adam how we have now arrived at a remarkable moment—prehistoric fossils coupled with new DNA technology have given us the tools to answer some of the basic questions of our existence: How do big changes in evolution happen? Is our presence on Earth the product of mere chance? This new science reveals a multi-billion-year evolutionary history filled with twists and turns, trial and error, accident and invention.
