Some say that the Yeti is a descendant of a race of giant apes, the Gigantopithecus Blacki, an extinct primate that lived in Asia and retreated into the Himalayas some 500 000 years ago.

There have only been a handful or teeth and jawbones of Gigantopithecus found throughout the world. The first tooth was found by in 1932 by a Dutch paleoanthropologist, G.H.R. Von Koeingswa in a Hong Kong apothecary shop. Since that time only a few jawbones and thousands of teeth have been found in China and India.

Paleontologists have described him as  a large, ground-feeding, ape-like genus about the size of a modern gorilla, with molar teeth well adapted to crushing tough material and flattened canines. It seems more plausible that the Yeti is a descendant rather than actually a living representative of Gigantopithecus.

Gigantopithecus is supposed to have died out hall a million years ago, but he or his descendants could possibly still survive.

However, there is no significant piece of evidence to support the theory that Gigantopithecus walked upright despite pronouncements that it did or may have. By its own size, it most likely did not. Moreover, none of its descendants evolved to walk upright and we know that no ape has ever evolved to walk upright naturally.

Stripped of its hair, the bipedal North American Sasquatch expresses many more human features than ape traits. A debatable statement since humans also have many ape-like qualities that they display without resorting  to walking on all fours.
