jaw

An article recently posted by Popular Science http://www.popsci.com/scitech/article/2009-08/do-animals-have-wisdom-teeth suggests that animals have room for wisdom teeth. An evolutionary biologist named Leslea Hlusko of the University of California, Berkeley, suggests that the shape of your jaw is partially determined by what you eat when you are growing up. Since unlike animals, humans cook all the meat they eat usually and do not just tear it off raw, jaws have become smaller in size. The article also suggests that if you eat a lot of raw carrots and other tubers as a child this may help to make the jaw larger when you get older and thus better accomedate your wisdom teeth so the wisdom teeth do not have to be removed.
