While our colleagues in Houston wonder "whether the public might actually learn something about early human history from Lucy's exhibition," we're with the Smithsonian on this one. Unlike old, fragile museum pieces of art, Lucy is still an active scientific subject, despite her deadness. As Slate points out, there's still research that can be done with her frail old bones. We thought of a treasure near and dear to our country's heart--the Declaration of Independence--and how, when it has gone on tour, solely copies have been used. (In some cases, "rare original copies" were used, a phrase which will make our brain hurt for at least a few days.) And then we ran across this:

The International Association for the Study of Human Paleontology, a group affiliated with UNESCO, passed a resolution in 1998 saying such fossils shouldn't be moved outside the country of origin. The resolution, unanimously approved by representatives of 20 countries, including Ethiopia and the United States, said replicas should be used for public display.
