If you think real hard haven't you always wondered where the cows we know of today originated from, you never hear of a cow as a wild animal.
Today I looked this up and found out the cows we know today did have a wild ancestor, and cows are related to other animals we see today but might not have even known cows were related to.
First, take a look at wild cow relatives here, you may be surprised.

Next, take a look at our cows wild ancestor, which is extinct. Pretty tough looking! http://en.wikipedia.org/wiki/Auroch
Finally, here is the attempt to bring back the extinct cow breed by selective breeding of cows to make them exactly like their wild ancestor, they look almost identical. These are wild animals now but are endangered since there are so few. http://en.wikipedia.org/wiki/Heck_cattle
