An ear that is aimd higher than the other flowerpot receive sound waves sooner from a stochasticity smash-up , and can therefore alert the mouse to an approaching bash predator (Gill , 2007 . The selective pressure in this grapheme is to head for the hills predation , which leads to longer life and reproduction of much takings who carry this trait . The mice without offset ears will be eaten in the beginning they are able produce offspring .

This natural alternative will provide increased fitness in the wooded environment , where sounds from the ground cover may put in with the mouse s ability to hear the approach of predators with nearly heavy wingsThe reason that this character change occurred in the first model is increased predation of mice by owls .
