Here we have a very nice example of how evolution is 'directed' by the environment, and an example of how the Theory of Evolution has explanatory powers that creationism simply does not have. This example is of a flightless member of the rail family of birds that evolved not once but twice on the small Indian Ocean atoll of Aldabra.
Julian P Hume of the Bird Group, Department of Life Sciences, Natural History Museum, Tring, Herts, UK and David Martill of the School of Earth and Environmental Sciences, University of Portsmouth, Portsmouth, UK, have shown that the present day flightless white-throated rail of Aldabra has some strikingly similar features to an extinct flightless rail. The extinct rail inhabited the atoll until climate change caused the sea level to rise and cover the atoll about 136,000 years ago, exterminating all plant and animal life.
