Changes

The blue mussel is one example of rapid, short-term evolution.  As the result of the [[Asian shore crab]] eating the blue mussel, they developed a thicker shell.  Researchers were able to use a distinct population of blue mussels that did not have the [[Asia]]n shore crab as a predator as a control that did not have the corresponding change in shell thickness.  Because the control group was not naturally selected to have a thicker shell thickness, they did not evolve.[http://evolution.berkeley.edu/evolibrary/news/060901_mussels]
