Диего де Ланда
Roper based his arguments on anecdotes from early Spanish colonists which called native Mesoamerican brocket deer goats: "Friar Diego de Landa noted, 'There are wild goats which the Indians call yuc.'" He quoted another friar in the late 16th century, "in Yucatán 'there are in that province ... great numbers of deer, and small goats'".
