A study by the Royal Botanic Gardens, Kew, and Queen Mary University of London reveals that Britain's ash trees are exhibiting natural selection in response to ash dieback, a deadly fungus. Initial concerns of widespread tree death are being mitigated as younger ash trees show genetic adaptations for greater resistance to the fungus. This suggests evolution is aiding the species' survival against the disease, which was first detected in 2012.
