Abstract
A comparison of two fruitfly genomes shows that much of their non-coding DNA is controlled by either negative or positive selection, dealing a double blow to the neutral theory of molecular evolution.
Once upon a time, the world seemed simple when viewed through the eyes of evolutionary biologists. All genomes were tightly controlled by various forms of natural selection.
