A computer science team at The University of Texas at Austin has found that robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. Beyond its implications for artificial intelligence, the research supports the idea that mass extinctions actually speed up evolution by unleashing new creativity in adaptations.

Computer scientists Risto Miikkulainen and Joel Lehman co-authored the study published today in the journal PLOS One, which describes how simulations of mass extinctions promote novel features and abilities in surviving lineages.

"Focused destruction can lead to surprising outcomes," said Miikkulainen, a professor of computer science at UT Austin. "Sometimes you have to develop something that seems objectively worse in order to develop the tools you need to get better."

    Nothing can accelerate evolution. Evolution just happens. When the environment changes, including other critters, naturally evolution provides different results. When the environment doesn't change, eventually an equilibrium will be had.

    The problem with your claim is that evolution is a theory of why, and to a limited degree how and in what way, organisms change. Since you grant that organisms can change via evolution at different rates, then that means that evolution, which is the process of change, can happen at different rates. Once you have that, then acceleration and deceleration of evolution are natural logical consequences.
