North American Animals
North American Desert Animals display a wide range of adaptations and inhabit niches similar
to their counterparts from other continents. One example of this parallel is peccaries in
North America and swine from Africa. The peccary (or javelina) is native to the Americas,
while true pigs (domestic swine, warthogs, etc.) are native to Africa. Although similar in
appearance, they are completely unrelated. Both eat similar foods and have similar social
structures, as well as other adaptations. True pigs occur in other parts of the world due
only to introduction by human settlers.
