Under the cold clear waters of Lake Huron, University of Michigan researchers have found a five and a half foot long, pole shaped piece of wood that is 8,900 years old.

The wood, which is tapered and beveled on one side in a way that looks deliberate, may provide important clues to a mysterious period in North American prehistory.

 This was the stage when humans gradually shifted from hunting large mammals like mastodon and caribou to fishing, gathering and agriculture, said anthropologist John O’Shea.  But because most of the places in this area that prehistoric people lived are now under water, we don’t have good evidence of this important shift itself just clues from before and after the change.
