The fact that living things evolve in the face of environmental change is not news, but a study now suggests that the process of evolution itself evolves, too.
The "evolvability" of evolution is a controversial concept, in part because it's difficult to measure. Living things typically adapt to their environments; for example, some bacteria rapidly evolve resistance to antibiotics. But does the process itself also change over time, and if so, what would drive the evolution of evolution?
