Bigfoot

A very large, hairy, humanoid creature from North American folklore reputed to inhabit wilderness areas of the U.S. and Canada, esp. the Pacific Northwest. Also, known as Big Foot, Sasquatch,The Abominable Snowman, or Yeti.

Yeti

The Abominable Snowman, or Metch-Kangmi in Tibetan, is a huge, hairy creature that walks upright and haunts the snowcappedsnow-capped peaks of the Himalayas. For years explorers have reported footprints measuring as much as 12½ by 6½ inches in the snow.

While leading an expedition on Mt. Annapurna in 1970, Don Whillans spotted a large, furry creature walking on two legs on a nearby mountain. He watched through binoculars for half an hour before the "snowman" vanished in a clump of trees.

Scientists believe bears, which can walk on two legs, could have left some of the footprints. Other observers suggest wolves, goats, snow leopards, or perhaps falling rocks or snow could be responsible. However, the Sherpa people of the region have traditionally believed that the Himalayan peaks are haunted by demons and spirits, while the Yeti, an ancient beast, prowls the mountains.

Yeren

Variously referred to as the Yiren, Yeh Ren, Chinese Wildman, "The Wildman of Shennongjia", Man-Monkey or "Man Bear" is said to be an as yet undiscovered hominid in China's remote mountainous and forested Hubei province.[1]

Many people think that there is a species and that the Yeti, Bigfoot, Yeren, Yowie, etc, are all related somehow and that when all the continents were together they traveled to different places and adapted very quickly. This theory has not been proven yet but many people believe it to be true.
