Hidden from the eyes of humankind, mythical creatures are said to live deep in the forests of Central America and high up in the mountains of the Himalayas. They go by the names Bigfoot and Yeti. Throughout history, scientists and explorers have been fascinated by these unknown creatures, which have been the source of inspiration for many films and stories. Amateur researchers like Matt Pruitt and Michael Mayes often roam the forests in the United States for days on end in search of Bigfoot. But even scientists like Jeff Meldrum, Professor of Anatomy and Anthropology at Idaho State University, believe they can prove that creatures like the Yeti really exist. Meldrum thinks they might belong to a species that is already thought to be extinct, the Gigantopithecus, a genus of giant apes. But could this really be true?
