Darwin's finches are icons of evolutionary biology. They all stem from a common ancestor, which arrived on the Galápagos Islands from the South American mainland some two to three million years ago. Unusually for a group of island-living birds, they have not lost any species through human interference. However, this state of affairs may not last, as the finches have come under attack by a number of manmade threats in the last decades. These threats include traffic, deforestation, and invasive species. Together, the Galapagos National Park, the Charles Darwin Research Station and an international team of scientists are working on solutions.
