The genus Equus initially evolved in the Americas (light blue). The earliest equids were found in the Great Plains and Western regions of North America.
From the Great Plains, equids spread to South America and the Old World, before becoming extinct in the Americas approximately 10,000 years ago for currently unidentified reasons (Janis and Bernor, 2019).
The domestication of the modern equids occurred in Eastern Asia (Wade et al, 2009). Extant equids include horses and burros as well as wild asses and zebras. (Jonsson et al, 2014)
