The mastodon tooth, now preserved at the Independence National Historical Park, is an artifact of Franklin’s role in the social and scientific movement called the Enlightenment. Further, the tooth was a building block for the natural philosophers of the 18th and 19th century as they came to understand the process of evolution.
