Paleopathology: A 20,000-Skeleton Perspective The diagnosis of various pathologies is a major tool for both archaeology and medicine. This set illustrates disease phenomena which are reproducible across geographic and even species lines. The antiquity of one disease -- rheumatoid arthritis -- varies geographically, possible evidence for its origin as vector-transmitted and for speculation about human behavior. By Bruce M. Rothschild. 63 slides -- $126
	Dental Anthropology By illustrating variations in human dental morphology and pathology. this set demonstrates the information anthropologists can gain about diet, behavior, nutritional stress and biological interrelationships of prehistoric and living populations. Included are archaeological specimens from India, Pakistan, and the Canary Islands. By John R. Lukacs. 90 slides -- $158
	Origins of Treponemal Disease, Distinguished According to Variety Syphilis, Yaws, and Bejel occur in more than 40 ancient populations. Yaws and Bejel can be traced back more than 6,000 years in the New World, possibly migrating with early Asian populations. Consistently represented for thousands of years, replacement of Yaws by syphilis is first documented 1800 years ago in the United States. The osseous record suggests possible infection of Columbus' crew. Thus, syphilis appears to be a New World disease, derived from Old World Yaws, and subsequently transmitted back to the Old World.
