Good fighters are bad runners

(University of Utah) For mice and men, a strength in one area of Darwinian fitness may mean a deficiency in another. A look at Olympic athletes shows that a wrestler is built much differently than a marathoner. It's long been supposed that strength in fighting, or protecting territory and resources, comes at the expense of running, or spatial mobility. Now an experiment with house mice provides evidence for this theory.
