One day, I encountered a group of second graders examining the displays of fossil hominids. I noticedthatonegroupofkidswasgatheredaroundadisplay,arepro- duction of a 17000-year-old human burial from a Pleistocene site in France.Ourreplicahadbeenarrangedintheexactstateofreposethat theoriginalskeletonheldfornearly18000years:legsandarmsflexed asifasleep,andsurroundedbygravegoods,includingstonetoolsand shellbeadsfromanecklace.Iapproachedthekidsandaskedwhatthey couldtellaboutthisperson.Mostsmiledandshrugged. ‘‘He’sdead,’’oneboysaidinaflatvoice.

THE NATIVE AMERICAN GRAVES PROTECTION AND REPATRIATION ACT On November 16, 1990, the 101st US Congress passed Public Law 101–601(HR5237;104STAT.3050),apieceofhumanrightslegislation betterknownastheNativeAmericanGravesProtectionandRepatriationAct (NAGPRA).1Acoalitionoflawmakers,NativeAmericanactivists,tribal elders, and leaders from the museum, archaeology and physical anthropologycommunitieswrotetoNAGPRA,toregulatethedispos- itionofNativeAmericanremainsandassociatedgravegoods. Manymuseumscontainedlargeskeletalandartifactcollections derivedfromWorkProgressAdministration2(WPA)-eraandotherexcav- ations of prehistoric and historic archaeological sites in the USA. In addition to human remains, NAGPRA also pertained to ‘‘associated funerary objects,’’ ‘‘sacred objects,’’ as well as ‘‘objects of cultural patrimony.’’ What constituted an ‘‘object of cultural patrimony’’ was opentobroader interpretation, despite the two pages-worthofcircui- tousdefinitionswithinthedocument. Institutions,suchaspubliclyfundedmuseums,universities,and federal agencies, were required by NAGPRA to create a summary of humanremainsandartifactsandsendittoculturallyaffiliatedNative Americantribes,nolaterthanNovember2,1993.Theinstitutionswere required to make complete and detailed inventories of human remains,associatedfuneraryobjects,anditemsofculturalpatrimony bythisdate,andthentosendthesummariestofederallyrecognized Native American tribes or Native Hawaiian organizations to which thesecollectionswereculturallyaffiliated.
