This question is about the article "Wild Horses as Native North American Wildlife"
Answer:
Most evidence suggests that the horses are in fact a native species, supporting the argument that the horses must have actually been in North America for more than 11,000 years.
Step-by-step explanation:
According to the article, wild horses of Spanish origin were taken to North America with Columbus and his entourage. They deposited these horses in Mexico, on Colombus' second voyage to the continent in 1493. The horses that were brought in at that time were E. caballus, which from where Mexico is today, began to spread across the Great Planices, intermingling in territory of the USA and giving rise to the native species we know today.
