The Subject

Evolution does not occur in a vacuum. It takes place against a background of changing conditions, some of a climatic or tectonic nature, some created by organisms themselves. The extent to which the rate and direction of evolution are controlled by organisms is the central question in a debate that has been raging for as long as evolution has been part of the intellectual vocabulary of scientists. In an effort to stimulate empirical work on the subject, we organized a symposium on the contributions that functional morphology and comparative physiology are making to paleobiology. The symposium was held as part of the North American Paleontological Convention on July 1, 1992, at the Field Museum of Natural History in Chicago. This issue of Paleobiology contains all the submitted and accepted papers presented at the symposium.

The present paper has been prepared in the course of work at the University of Illinois for the degree of master of science in zoology. In addition to extensive collections of Entomostraca made at the Biological Station of the University of Illinois, situated at Havana, on the Illinois River, I have been able, through the kindness of Dr. S. A. Forbes, to examine all the accumulations in this group made by the Illinois State Laboratoryof Natural History during the last twenty years,and covering a territory little less than continental.

We are indebted for the material from which the following notes have been compiled to Principal Dawson, of Montreal, and to the Secretary of the Portland Society of Natural History, to whom our best thanks are due for the opportunity thus afforded us of comparing the fossils of the North American Clay Beds with those of our own country. By carefully washing theclays kindly forwarded to us, we have obtained many specimens in excellent condition for examination.

The modern North American anti-cult movement (hereafter ACM), a counter- movement, has been researched both conceptually and historically/organizationally. My purpose here is not to trace all the historical and sociological trivia and varieties of the ACM in North American during its thirty five-year heyday of growth, maturity, and then relative morbidity. Rather, I wish to accomplish two tasks: first, to place the understanding of counter-movements such as the modern ACM in a sociological social movement context (foreign as that may have seemed to its activists during the 1960s-90s); and second, to provide an overview of this current incarnation of a very old social movement theme in American history. Regarding the subject of counter-movements, Tahi Mottl correctly claimed thirty years ago that it was a relatively neglected one. Things are becoming slightly better today.

Contemporary Development

Since the calls "cabinets of curiosities", the essence of natural history was consolidating itself with the birth of the museums and the development of the Museums of Natural History. This consolidation was reached through following activities: expeditions, field trips, collection classification works, catalogues of diffusion of scientific knowledge, educativ activities and expositions. The present paper intends to discuss the importance of the museal institutions for the studies of Paleontology; since the museums of Natural History had exerted a pioneering paper in the institutionalization of certain areas of knowledge, as Palaeontology, Anthropology and Experimental Physiology, in Brazil. The Paleontological studies in museums had collaborated in the specialization and modernization of the appearance of "new museum idea". As this new concept the museum is a space of diffusion of scientific knowledge, represented as an object that reflects the identity of the society without an obligator linking with physical constructions. However, the Brazilian museums have been sufficiently obsolete, with problems that involve acquisition and maintenance of collections to production of temporary or permanent exhibitions. When the Brazilian institutions of natural history are analyzed they are not organized on the new museum conception and the digital age as the North American and European ones. Despite the difficulties found by the Museums since its birth as Institution in the 18th century, the contemporary development of Museology and Palaeontology as Science had contributed for the consolidation and institutionalization of both, helping the diffusion of scientific knowledge.

Dr Marshall McKusick is Associate Professor of Anthropology in the Department of Anthropology, University of Iowa, USA. He and others have been concerned with the rise of antiquarian speculation in the United States, which is historically comparable to mound-builder theories of a century ago that gained great popular currency. Professor McKusick's book on the subject of the various speculations Atlantic voyages to prehistoric America, will be published early next year by the Southern Illinois University Press, Carbondale.

AbstractA reassessment of the taxonomic relationships of North American gigantopterids is presented in light of an examination of large populations of specimens housed in the US National Museum of Natural History. Variations in venation and subtle aspects of leaf shape facilitate refined understanding of the relationships and diversity of the North American gigantopterid species leading to an improved understanding of the taxonomic and biogeographic relationships of this group, which are found most abundantly in western equatorial Pangea and Cathaysia. Current literature suggests that there are eight North American genera, however, this study has revealed a morphological overlap of several previously defined genera, leading to the conclusion thatGigantopteridiumencompasses the species previously treated asCathaysiopteris yochelsoniias well as a new species,Gigantopteridium utebaturianum. The transfer ofC.yochelsoniitoGigantopteridium yochelsoniisuggests thatCathaysiopterismay represent a genus endemic to Cathaysia, limiting the biogeographical connection between the regions toZeilleropteris,Gigantopteridium,Euparyphoselis, andGigantonoclea.
