Bread mold genomes demo 'reverse-ecology'

In a demonstration of “reverse-ecology,” UC Berkeley biologists have shown that one can determine an organism’s adaptive traits by looking first at its genome and checking for variations across a population. The study offers a powerful new tool in evolutionary genetics research, one that could be used to help monitor the effects of climate change and habitat destruction.
