Collecting and exhibiting human remains raises ethical questions today. Human remains are therefore considered "sensitive objects". In addition, objects with religious significance and objects whose acquisition, origin and production are questionable or unknown are also considered sensitive. Central to dealing with "sensitive objects" is transdisciplinary research into their origin (provenance research). The significance of human remains can be understood differently depending on the context or the spirit of the times. This is why the International Council of Museums ICOM formulates guidelines in which it refers to the duty of care in view of the origin of the objects. According to ICOM, the scientific study and exhibition of "sensitive objects" must be carried out "in compliance with professional standards and take into account the interests and beliefs of the social, ethnic or religious groups from which the objects originate, insofar as these are known". According to ICOM, if the origin of an object is unknown, it should not be exhibited. Requests for restitution from societies of origin should be pursued with respect and sensitivity. It is important for us to emphasise that human remains are human beings. The deceased were and are treated and buried on the basis of specific and diverse ideas. The views and practices of the societies of origin should determine how human remains are treated.
