Remote Scottish wrens are growing twice as large as mainland birds in a rare glimpse of evolution in action
Researchers have discovered that wren populations on remote Scottish islands are evolving to be significantly larger than their mainland counterparts, a phenomenon known as 'island gigantism.' The study highlights how genetic isolation drives distinct evolutionary paths in similar environments.
