Final answer:
The American Fuzzy Lop rabbit is a breed that originated in the United States, distinct from sheep and unrelated to Cortés's introduction of sheep in the southwest or the Navajo sheep.
Step-by-step explanation:
The American Fuzzy Lop is a breed of rabbit that originated in the United States. It is not related to the Navajo sheep or the introduction of sheep to the southwestern United States by Cortés. Instead, the American Fuzzy Lop is a breed of rabbit that was developed in the 20th century, primarily for its wool which resembles that of the Angora rabbit.
While sheep have played an important role in agriculture and the conflicts over grazing land during the westward expansion, the American Fuzzy Lop rabbit is a separate and distinct animal bred for different purposes.
