Why are guinea pigs called pigs?

Introduction: The Origin of the Name "Guinea Pig"

Have you ever wondered why guinea pigs are called pigs? Despite being neither pigs nor originating from Guinea, these small rodents have been known as guinea pigs for centuries. The name guinea pig is believed to have originated from the mistaken idea that they were a breed of pig from Guinea. However, the true origin of the name is not quite clear-cut and involves a complex history of cultural and linguistic connections.

The First Encounter: Europeans Meet the Guinea Pig

The first European encounter with guinea pigs was in the early 16th century when Spanish explorers arrived in South America. They observed the indigenous peoples of the Andes keeping guinea pigs as pets and for food. The Spanish brought guinea pigs back to Europe as exotic curiosities, where they became popular pets among the wealthy. The guinea pig’s unique characteristics, such as their gentle nature and vocalizations, made them popular pets and subjects of study.

The Resemblance to Pigs: Physical Characteristics

Although guinea pigs are not related to pigs, they do share some physical characteristics. For example, they have a stocky body with short legs and a rounded snout. Additionally, both pigs and guinea pigs are herbivores and enjoy eating similar foods. The physical similarities between the two animals might have contributed to the naming of guinea pigs as pigs.

The Phonetic Connection: Similar Sounds in Different Languages

Another theory about the origin of the name "guinea pig" is that it comes from the animal’s vocalizations. In some languages, the guinea pig’s sounds resemble those of pigs, which could have led to confusion between the two animals. For example, in French, guinea pigs are called "cochon d’Inde," which translates to "pig from India."

The Cultural Association: Guinea Pigs in Folklore and Literature

Guinea pigs have appeared in folklore and literature throughout history. In South America, guinea pigs were considered sacred animals and featured in religious ceremonies. In Europe, they were popular pets and even appeared in children’s stories and nursery rhymes. The cultural significance of guinea pigs could have contributed to the adoption of the name "guinea pig."

The Guinea Pig in Science: Taxonomy and Classification

In the 18th century, the Swedish scientist Carl Linnaeus classified guinea pigs under the order Rodentia. This categorization recognized their relationship to other rodents such as rats and mice. Despite this scientific classification, the popular name "guinea pig" remained, and the animal became known as Cavia porcellus.

The Evolution of the Name: From "Indian Pig" to "Guinea Pig"

Before becoming known as guinea pigs, these animals were referred to as "Indian pigs" or "Peruvian pigs." It wasn’t until the 17th century that the name "guinea pig" became widely used. The reason for this change is not clear, but some scholars speculate that it was due to confusion between Guinea in West Africa and Guyana in South America.

The Use of Guinea Pigs in Research: A Historical Perspective

The guinea pig’s small size and gentle nature made them ideal research subjects.
