Is athleticism linked to brain size? Researchers performed laboratory experiments on house mice and found that mice that have been bred for dozens of generations to be more exercise-loving have larger midbrains than those that have not been selectively bred this way -- the first example in which selection for a particular mammalian behavior has been shown to result in a change in size of a specific brain region.
