“There have always been stories about animals that bring up children. One of the most famous is the story of Romulus and Remus; the twin boys who were raised by a wolf. When the brothers grew up they founded the city of Rome. While this is a legend, there are many modern stories about children being raised by wolves, which are believed by many people. In an Indian jungle in 1867 a boy was found by some hunters. They said he was living with wolves – he was about six years old. He was named Dina and went to live with humans, but he never learned to speak. The wolf-girls Kamala and Amala were also Indian. Their story was reported by a priest who said the girls were discovered in 1920. Although this story is widely believed, recent examinations of the account have cast doubt on it. It seems more likely that the girls were autistic and had been rejected by their family.

There are also stories about human children who were cared for by other types of animal. In 1724 a boy of about 12 was seen in the forest near Hanover. He was known as Wild Peter. It is unclear what kind of animal Peter lived with, but he didn't eat meat; he ate tree bark, like deer. This is similar to the story of the Syrian Gazelle Boy, who was spotted in the desert in 1946. The boy was reported to be living with a herd of gazelles. He ran very fast on all fours and ate the same food as the gazelles. However, reports about this child are inconsistent and there is no record of what happened to him.

Marina Chapman is from Colombia and is now about 65. She claims that when she was five she was kidnapped and ended up living in the jungle with monkeys. After a few years she was rescued by hunters. As there are no official records, her story can't be disproved, but her original family has never been found.

More recent stories are about children who were neglected by their parents and were looked after by animals. There are videos on the internet of Oxana, a Ukrainian girl, who moves and behaves very much like a dog. She was found in 1991 living with the dogs in her parents' backyard. Oxana's case is well- documented and experts agree that for about five years she really lived with dogs.

Many other cases, however, may have little basis in reality.”
