They are known by the scientific name Cavia porcellus. This name comes from Latin words meaning "little pig." Even though they have "pig" in their name, they are not related to pigs. They are actually part of a group called cavies. In the wild, they live in small groups called herds. These herds usually have one male, called a boar, and several females, called sows. The babies in these groups are called pups.

These animals have a very interesting way of staying healthy. One important thing is how they use their teeth. Guinea pigs have four front teeth that never stop growing. Because they grow continuously, the animals must chew on things like wood. This helps wear the teeth down so they do not get too long. They also need to eat certain things to stay well. Just like humans, guinea pigs need to get vitamin C from their food. Without this vitamin, they could develop a sickness called scurvy.

History shows that guinea pigs have been around for a very long time. People in the Andes region of South America first domesticated them around 5000 BC. These early people used them as a source of food. The Moche people of ancient Peru even showed them in their art. Later, the Inca people used them in special religious ceremonies. Between 1200 and 1532, people used selective breeding to create different types. This means they chose certain animals to have babies with. This helped create the many different breeds we see today.

Scientists have also used them for a long time. Since the 17th century, they have been used in biological experiments. In the 19th and 20th centuries, they were used so often that people started calling human test subjects "guinea pigs." Today, researchers use them to study medical conditions like diabetes and tuberculosis.
