  • How ferns adapted to one of Earth's newest and most extreme environments

    23 October 2014, 2:00 pm

    Ferns are believed to be 'old' plant species – some of them lived alongside the dinosaurs, over 200 million years ago. However, a group of Andean ferns evolved much more recently: their completely new form and structure (morphology) arose and diversified…
