Abstract:

A mysterious discovery has stumped scientists who study genetics at the cellular level for over a decade. Our genome, or collection of genes, has undergone many evolutionary changes since humankind first emerged millions of years ago, including parts of it that play a critical role in development and survival. Yet hundreds of small segments of our DNA have remained virtually unchanged not only among human beings, but across many other animal species whose lineages diverged before the time of the dinosaurs.
