GREGORY, Curator The following exhibits have been completed or installed during the past year: Exhibits 1. "Family Tree of Man." Installed in the Hall of the Age of Man. This exhibit includes a series of sixteen models of skulls prepared by members of this department in coöperation with the Department of Preparation; it represents the various forms of extinct and recent races of men and of anthropoid primates, arranged on a large model of a tree in accordance with their family relationships. Six of the original models of skulls were prepared by Prof. J. H. McGregor with the assistance of Miss Roigneau; the remaining ten were prepared by Mr. Otto Falkenbach under the direction of the curator. The model of the tree and the background were prepared by Messrs. Jansson and Hope, under the direction of Assistant Director Clark and the curator. This exhibit is the product of many years of research by members of the Museum staff and their colleagues in this country and abroad. It is, of course, not a final or complete visualization of the genealogical relationships of man, but it rests upon a broad, constructive, conservative interpretation of many thousands of recorded facts in the fields of comparative and human anatomy, palæontology and other branches of science. The spirit of the exhibit is expressed in the following excerpt from the master label: "As yet we know but little of the direct fossil ancestors of man, but the fossils represented by stages 1, 2, 3, 4, 5, 6, 7, of this 'Family Tree' are important milestones along the immensely long road of man's evolution." Five complete copies of the exhibit have been made for sale to other educational institutions, and of these, four have already been sold. 2. "Comparative Anatomy of Man and Anthropoids." Installed in the Hall of the Age of Man. This exhibit was also prepared by members and associates of this department in coöperation with the Department of Preparation. It shows a series of casts of the brain cavity of anthropoids and of extinct and recent men, as well as half sections of the skulls and half sections of the lower jaws. It brings out very clearly the fundamental unity 98 L DEPARTMENT OF COMPARATIVE ANATOMY "FAMILY TREE OF MAN" Milestones along the road of man's evolution |
