M.K. Davis has an interesting video about Native Americans and in the West and discusses the possibility that perhaps Bigfoots may have been kidnapping Native American women. The hybridization is evident in some photographs such as one photograph that shows two Native American men with abnormally long fingers compared to their palm. There's also an unusual amount of hair on their legs and chest of the men. One person seems to have hair that resembles a different color other than black, perhaps reddish. "There was some strangeness to these people," Davis notes.
Here's one famous story about a Paiute girl who was kidnapped by a red Bigfoot:
In the other story my uncle had heard that a few of the Mono Lake Paiute girls were out gathering berries in Piute Meadows, which is located in northern Yosemite National Park. When suddenly one of the girls who was on the edge of the meadow by the trees was heard screaming. The girls ran over there as one of the girls went to call the men. There was no trace of her. She had vanished. The people believed that she was taken by a Grizzly bear or some spirit had captured her. At the camp the family cried and was inconsolable, but the people had to go on. The next day the people started up the hill to trek along the Sierra suddenly in rear was heard a screaming and yelling. It was the girl crying, upset and yelling nonsensical things. She was moving her hands wildly and pointing back to the wooded area. She told the people that as she was picking berries along the meadow by the edge of the forest when a Big Foot or Pahi-zoho had come out behind a tree and grabbed her. He was big, reddish and hairy and she screamed and screamed. He had carried her off and she thought for sure he was going to eat her, but instead he took her into the bushes and forced himself on her. She said he stunk so bad, that it was making her sick and it was extremely painful, that he didn’t talk but grunted all that time. She was too scared to look at him, but could see his reddish big hands and hairy legs and feet, that even his feet had hair on them. They didn’t look human. She said after awhile he just went to sleep, but still had her in his grip in his arms. That his arms were very large and she just laid there scared and thinking that after that he was going to kill her. That he snorted and snored loudly all night long and suddenly almost in the morning he completely lost his grip and she made a quick dash. She ran like she had never run before for she feared for her life. Now she was safe with her people and her family, but later on she started to show signs of pregnancy. The people stayed clear of her accept her friends and family. Nine months later she had a son, a big red headed baby boy who was very hairy. The people were scared at first and some of the men wanted to kill him, but the girl’s mother prevented them. Later the people accepted him into the group for he was a good hunter and he had uncanny natural abilities of sight and smell and was very strong. He married and his children came out more normal looking, but every now and then one of his descendents comes out hairy and with red hair. Many of his descendents are now scattered in many of the Paiute tribes in California and Nevada.
