Krantz, the anthropologist who investigated sound recordings, also discussed alleged Bigfoot hair, feces, skin scrapings and blood in his 'Big Footprints' book. There is no hard evidence for the existence of Bigfoot. He listened to at least 10 tapes and found 'no compelling reason to believe that any of them are what the recorders claimed them to be,' Live Science previously reported. The late anthropologist Grover Krantz investigated sound recordings claimed to be of Bigfoot for his book ' Big Footprints: A Scientific Inquiry Into the Reality of Sasquatch (opens in new tab)' (Johnson Books, 1992). Jolanta Kowalski, Ontario’s Ministry of Resources and Forestry media relations officer, told Vice News (opens in new tab) at the time: “Our biologists say it could be a larger mammal–for example a wolf–but because it’s a considerable distance from the recorder there is no way to know for sure.”

In 2019, for example, a YouTube video (opens in new tab) of mysterious howls and screams in a forest in northwestern Ontario, Canada went viral, driving Bigfoot speculation. Strange noise recordings associated with Bigfoot occasionally attract media attention but the noises can often be attributed to known animals, such as foxes (opens in new tab) or coyotes (opens in new tab).Įxperts can't always identify the exact animal in strange recordings that cryptozoologists, people who search for creatures rumored to exist, point to as Bigfoot evidence. The creatures are also associated with other noises, such as wood-knocking, according to Scientific American (opens in new tab). Some people claim to have heard Bigfoot shrieks (opens in new tab), howls, growls, screams or other vocalizations. The logical explanation for this discrepancy is that the creatures don't exist, and that photographs of them are merely hoaxes or misidentifications. With the rise of high-quality cameras in smartphones, photographs of people, cars, mountains, flowers, sunsets, deer (opens in new tab) and more have gotten sharper and clearer over the years Bigfoot is a notable exception. The video's authenticity is still debated but it was likely a hoax, with the ape-like figure just a human wearing a costume. The most famous Bigfoot video is a short film taken in 1967 by Roger Patterson and Bob Gimlin, known as the 'Patterson–Gimlin film,' or 'Patterson film.' Shot in Bluff Creek, the video shows what appears to be a large and hairy bipedal ape, or Bigfoot, striding through a clearing. Related: Real or not? The science behind 12 unusual sightings (opens in new tab) Bigfoot video and photographs When it comes to cryptids like Bigfoot, the human brain is capable of making up explanations for events it can't immediately interpret, and many people simply want to believe they exist, Live Science previously reported (opens in new tab). In the same vein, people also often overestimate their ability to remember things. In crime cases, for example, witnesses can be influenced by their emotions and may miss or distort important details. Unfortunately, these are based on human memories, and memories are not reliable, Live Science previously reported (opens in new tab). In these accounts, Bigfoot is usually described as being about 8 to 10 feet (2.4 to 3 meters) tall and covered in hair.Įyewitness reports, or sightings, are the most common evidence put forward for the existence of Bigfoot. in the last 50 years, Live Science reported (opens in new tab) in 2019.
