A paleoanthropologist conducts research at a remote fossil site in eastern Africa. The anthropologist is a researcher based at a major university in the United States, and he spends 6 weeks every summer excavating and cataloging fossil materials at the site. The anthropologist has been working in this area for over 15 years, and he has formed close partnerships with local scholars and residents. His current field team is made up of students from the United States and from Kenya, as well as professional colleagues from both countries. He also hires residents from the local village to help with the excavations and to act as field staff, including drivers, cooks, and guides. 1. In answering each question, be sure to support your choice with relevant information from the AAPA Code of Ethics. In this situation, the anthropologist is studying fossil materials that are over 2 million years old. From whom should he obtain informed consent for his work?
2. If he continues to work here for the next 10 years, how often should he reobtain informed consent? Should this be done at regular time intervals? Or should it be done only when something changes (for example, if he moves to a different excavation area at the site)?
