Animals with large brains are considered to be more intelligent and more successful than those with smaller brains. Researchers have now provided the first experimental evidence that large brains provide an evolutionary advantage. Large-brained female fish have a higher survival rate than those with small brains when faced with a predator, although brain size surprisingly did not influence male survival.
