Like apples\uff0ccarrots are native to Central Asia. Thats why horses, which also come from Central Asia, like both apples and carrots so much.(16) With wild carrots, the roots are white, small and skinny, so youd have to pick a lot of wild carrots to get enough to eat.

It is the child of a donkey and a horse. ( 22) Mules have strong muscles like horses, but they eat less, can work longer, and are gentler, like donkeys.George Washington was the first person in the United States to own mules.
