From early in its history, the "Ancestors" project was designed to be multifa­ceted. In addition to the exhibition of original human fossils, the idea of a symposium at which curators of these fossils could present the results of their current work was among the first aspects planned. Once approval for the project was received, it was decided that a symposium volume would be a logical addition. This book is thus the outcome of the Ancestors symposium, "Paleoanthropology: The Hard Evidence," held from April 6 to April 10, 1984.

Each curator bringing fossils to the exhibit was invited to present a paper. About half accepted; the others, not specialists in paleoanthropology, declined. On the basis of the titles offered by these curators, a second group, consisting of colleagues with major research interests complementing those of the curators, was invited to participate in the scientific aspect of "Ancestors" by presenting a symposium paper (or chairing a session) and taking part in the fossil-study sessions. Almost all of the contributors to the symposium submitted papers for publication -- the few exceptions are noted in the introductory sections. Owing to financial exigencies, the majority of the participants thus invited were Americans, but a number of our most active colleagues from Eurasia and Africa were also included.

The symposium was planned to represent more of a stock-taking -- a summary of the state of paleoanthropology in the mid-1980's -- than a source of new directions, although some of those were included. The speakers were asked to concentrate on aspects or implications of the "hard evidence," the fossils themselves, in light of the direct association with the exhibition of original fossils. Again, in view of this focus, archeological presentations were not solicited, since within the time available broad­ening the range of topics would have meant reducing the depth of those covered.

The Wenner-Gren Foundation for Anthropological Research cosponsored the symposium with the American Museum of Natural History. In addition, Mrs. Lita Osmundsen, Director of Research at Wenner-Gren, joined Ian Tattersall, John Van Couvering, and myself on the Symposium Committee and gave us the benefit of her years of experience in organizing meetings of all sizes. The generous support provided by Wenner-Gren for the symposium and its publication was vital, and Mrs. Osmund­sen's active participation was itself an indispensible element in the success of the entire scientific program.

Although the study session is described in the first article, it is appropriate to note two aspects here. First, most of the financial support for that period of compara­tive study and research (apart from expenses for the curators) came from the Anthro­pology Program of the National Science Foundation and the L.S.B. Leakey Foundation; without this aid, combined with that from Wenner-Gren for the symposium, the scientific sessions would simply have been limited to the participating curators and would therefore have had much less lasting value and impact.
