A drawing/portrait artwork of a Gigantopithecus – A species of great ape that went extinct as much as 100,000 years ago. The ape stood about 10-12 ft. tall and about 1200-1400lbs at most, this being a real ape that once existed amongst primitive humans. In theory, this animal is believed to be the ancestor of our today’s Bigfoot/Sasquatch/Yeti legend. In ways it makes more sense than just having a random ape walking around North America. This theory to many is the most realistic but also still very controversial/skeptical to others.
