Loan-shift and translation of unfamiliar fauna
The Septuagint and other ancient translations regularly map unknown animals onto familiar names. Hebrew re’em becomes “unicorn” in the KJV. The issue is not dishonesty. It is what translators do when the receptor language lacks the exact beast.
If Nephi’s Reformed Egyptian used a term Joseph rendered “horse,” the English word may name an American equid, a tapir-like mount in a loan-shift (a hypothesis, not a dogma), or a real Equus whose American timeline is still debated. Overconfidence on any one of those is unwise. So is the critic’s overconfidence that 1830 archaeology had the last word.
