Chickens and Sheep
....
..(3 Nephi 10:4-6)..
Archaeologists have recently found evidence of pre-Columbus chickens in the Americas.
“All uncertainty about the pre-Columbian presence of chickens was laid to rest recently by two forms of evidence, one linguistic and the other archaeological, that appear to establish beyond question that the chicken was known among ancient inhabitants of Mexico. The ancient Proto-Mixe-Zoquean language of southern Mexico (hypothesized to have been used by the ancient Olmec people) has been partially reconstructed on the basis of lexicons from descendant languages. A name for chicken emerged in that reconstruction. The word is distinct from names for turkey or other fowls. This appears to be good evidence the Old-World chicken arrived on ships to Mesoamerica long ago. Furthermore, to anchor the case, archaeologists recently found chicken bones in a Classic Maya site.” (John Sorenson, Mormon’s Codex, p. 155)
