Australian equivalent of the yeti, or "Abominable Snowman." The first account of the yowie appeared in 1835 when a Mr. Holman said of his trip to the subcontinent, "The natives are greatly terrified by the sight of a person in a mask calling him 'devil' or Yah-hoo, which signifies evil spirit." By 1840, Australian scientists were debating whether or not the yahoo was an imaginary being or a real, but rare, species. By the 1880s European settlers began to report seeing something that resembled a huge monkey or baboon. Through the first half of the twentieth century occasional reports appeared, almost all from New South Wales and Queensland. Along the way, "yahoo" became "yowie."
A new set of reports arose in the 1970s following the sighting of some large (too large to be a human), humanlike tracks by an Australian Air Force surveying team on Sentinel Mountain. In the late 1970s Rex Gilroy founded the Yowie Research Center and now claims over 3,000 sightings.
The yowie has been integrated into the field of cryptozoology, but remains one of the more doubtful creatures under consideration. Australia has no naturally occurring primates other than humans. The major champion of the yowie's existence is Graham C. Joyner, who has argued that it is a bear-like marsupial.
