The more two DNA sequences differ, the longer ago they shared an ancestor. But raw differences undercount, because a site can mutate more than once. The Jukes–Cantor correction inflates the raw distance to estimate the true number of substitutions per site. Educational tool.

Reading this result: About 15.0% of sites differ, and the Jukes–Cantor correction inflates that to 0.167 substitutions per site to account for hidden multiple hits.
