The San Diego Natural History Museum has an exhibit called Horse, which features a number of artifacts (and facts) about the domestication of the horse and its contribution to our society.
Of course, you can bet many of the exhibit displays show all types of horses, horse related artifacts, photos and videos. But then you run into a display on Indian zebus (a bovine species) and can’t help but wonder how it got into the horse exhibit.
There’s only one explanation for this cow display. Cows are such a big part of our society, they just can’t be left out for any reason. It’s as simple as moo.
