S4·E5 Siberian Snowman

Up in the icy mountains of Siberia in southern Russia, there have been a rash of recent sightings of a beast known as the Siberian Snowman. Similar in description to Bigfoot, this nine foot tall creature may, in fact, be related to a nearby archeological find that recently uncovered a new human ancestor. Could there be a few of these pre-humans lurking in the mountains?
