Key quote from the article:
There are at least two possible resolutions to the “horse” problem in the Book of Mormon: (1) definitions were expanded to include new meanings and (2) horses were present but their remains have not been found.
The Book of Mormon is a volume of holy scripture comparable to the Bible and is a record of God's dealings with His chosen people in the New World. The main purpose of the Book of Mormon is "to the convincing of Jew and Gentile that JESUS is the CHRIST, the ETERNAL GOD, manifesting himself unto all nations." (Book of Mormon Title Page) It was written by ancient American prophets for our day (Mormon 8:35) and is an American testament of the Lord Jesus Christ.
