The theory that grizzlies once walked upright is not rooted in scientific evidence. This concept is likely a myth or folklore rather than a factual explanation of any part of the natural world.
"When Grizzlies Walked Upright," tells the story of the origin of all Native American people. In the story, the Chief of the Sky Spirits shows human qualities in punishing the grizzlies by making them walk on all fours and making them no longer talk.
The ancestors of dinosaurs walked upright before they evolved into true dinosaurs. The earliest known dinosaur, Eoraptor, walked with upright legs underneath its body.
they walked upright
Australopithecus is considered the first species believed to have walked upright. Fossils of Australopithecus show evidence of bipedalism, indicating they were able to walk on two legs, which was a significant step in human evolution.
Austrapithecus (australopithecines)
There have been many primates that walked upright and were bipedal, the first is generally considered to be Australopithecus afarensis, which lived in Africa More human like versions would be included in the 'homo' genus, such has the neanderthals.

The first species believed to have walked upright on two legs is Australopithecus afarensis, with the most famous example being the fossil "Lucy" discovered in Ethiopia. This early hominin species lived approximately 3.9-2.9 million years ago.
The name Homo erectus was given to this species because of its upright posture compared to earlier human ancestors. "Erectus" means upright in Latin.
bottom of the skull because early hominids walked upright
Homo habilis likely walked bipedally, meaning on two legs. This is based on the structure of their pelvis and leg bones, which show adaptations for upright walking. This early human ancestor is thought to have had a more efficient form of walking compared to other primates.
