"Ox" or "oxen" is mentioned six times in the Book of Mormon (Ether 9:18; 1 Nephi 18:25; 2 Nephi 17:25; 2 Nephi 21:7; 2 Nephi 30:13; Mosiah 13:24). Some critics charge that this is an anachronism because, they claim, an "ox" is a castrated bull — something that would be impossible to find in the wild (see 1 Nephi 18:25). Ox, however, also refers to members of the subfamily Bovinae, in the Bovidae family, which includes Asiatic buffaloes, African buffaloes, cattle, and bison. A glance at a good encyclopedia will reveal the listing of other "wild ox" such as the yak, banteng, and the wild North African ox. Some LDS scholars have suggested that the Book of Mormon "ox" may refer to the tapir, camelidae, or perhaps bison.
