The domestic guinea pig or simply guinea pig (Cavia porcellus), is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not in the pig family Suidae, nor do they come from Guinea in Africa. They originated in the Andes of South America; studies based on biochemistry and hybridization suggest they are domestic descendants of a closely related species of cavy such as C. tschudii, and therefore do not exist naturally in the wild.
