Contesto

Scottish wrens may be evolving into new species through island gigantism Tiny birds on remote Scottish islands are undergoing a dramatic evolutionary transformation. Scientists studying four isolated populations of British Wrens discovered that some island birds have grown astonishingly large — with the biggest St Kilda Wrens weighing more than twice as much as the smallest mainland birds.

Scientists studying four isolated populations of British Wrens discovered that some island birds have grown astonishingly large — with the biggest St Kilda Wrens weighing…
