Evolution does not have foresight. But organisms with a greater capacity to evolve may fare better in changing environments. This raises the question: Does evolution favor characteristics that increase a species' ability to evolve? For several years, biologists have attempted to provide evidence that natural selection has acted on evolvability. Now a new article offers clear evidence that the answer is yes.
