Angus cows are bred to increase muscle mass so that we can get more meat out of them Main purpose is money Farmers raise corn that has been made virus-resistant by adding a gene Dogs of having a desirable coat color are bred with one another to produce more puppies with that same coat color. Giraffes with short necks cannot get enough food. After a few generations, only the long neck giraffes have survived. Finches have developed different bird beaks because they eat different types of food Dark colored moths have become more prevalent because they can camouflage against trees.
