‘Bigfoot’ Spotted in Yellowstone?


Our favorite lumbering ape-man, Bigfoot, has been spotted again—this time, hanging out near bison in Yellowstone National Park, according to a new video. (National Geographic News)

Queue the video up to about 2:55 and look behind the bison to see what all the fuss is about.


  • How did the geneticists in the Nat Geo News article apply scientific analysis to the legend of Bigfoot?
    • Scientists tested hairs purported to have come from the giant ape. They extracted DNA from the hair and tested the it against known species. The hair belonged to bears and other well-known animals.


  • What DNA evidence would actually support the existence of Bigfoot?
    • Scientists could test unknown hair, extract DNA, and fail to match it to any known animal. They may link some genetic markers to primates such as humans, chimpanzees, or orangutans, which would suggest the unknown animal was a primate. This has not happened.

  • Take a look at the 2008 map of Bigfoot sightings above, or take a look at the Geographic Database of Bigfoot/Sasquatch Sightings and Reports. Where do the majority of Bigfoot sightings take place? What might be some reasons for this? (In other words, describe Bigfoot’s habitat.)
    • Most Bigfoot sightings seem to be recorded in western states, such as Washington, Oregon, and California.
    • Many sightings seem to take place in areas with undeveloped forests. As a top predator, the Bigfoot species would need huge swaths of undisturbed territory to support a healthy breeding population.


  • Do you think Yellowstone National Park supports a Bigfoot-friendly ecosystem?
    • Yellowstone definitely supports a healthy forest ecosystem, although there have been very few Bigfoot sightings there.
