8th Biennial Meeting of the International Society for Evolutionary Protistology; College Park, MD; July 1990

原生生物是真核生物的一个不同的群体， 包括藻类、真菌和原生动物， 原核生物之间的中间组织水平 （细菌和蓝绿藻）和更高度组织化的 植物和动物的群体。 原生生物通常被用作 细胞生物学实验室研究中的实验生物。 了解原生生物之间的进化关系 藻类、真菌和 原生动物由不同的研究者群体进行研究。 然而，在过去几年中， 组织起来，研究不同国家之间的相似性和差异性， 三组，并建立标准的命名为 它们共享的结构。 这项仔细的研究应该 允许调查人员将相似之处区分开来， 共同的祖先（同源性），由于共同的 类比（Analogies） 第一个这样的努力完成是 鞭毛体和细胞骨架的特别小组 研究结果将在特设工作组第8次会议上介绍。 国际进化原生生物学会 公园，马里兰州。 拟议的工作队会议及其相关的 诉讼数量将产生广泛的影响。 这种综合将 在细胞生物学家、进化生物学家、 生物学家和系统学家的藻类，真菌， 原生动物 这些研究结果将有助于扫清道路， 为了更好地理解古代的多样化 更高的生物。

The protists are a diverse group of eucaryotic organisms, including the algae, fungi, and protozoa, united by their intermediate level of organization between the procaryotes (bacteria and blue-green algae) and the more highly organized groups of plants and animals. Protists are commonly used as experimental organisms in laboratory studies of cell biology. Understanding the evolutionary relationships among protists groups has been impeded by the fact that algae, fungi, and protozoans are studied by separate communities of investigators. During the past few years, however, several Task Forces have been organized to study the similarities and differences across the three groups, and to establish standard nomenclature for structures that are shared by them. This careful study should allow investigators to separate similarities that are due to common ancestry (homologies) from similarities due to common function (analogies). The first such effort to be completed is the Task Force on the Flagellar Apparatus and the Cytoskeleton. The results will be presented at the 8th meeting of the International Society of Evolutionary Protistology, in College Park, Maryland. The proposed Task Force meeting and its associated proceedings volume will have wide impact. This synthesis will open new discussions between cell biologists, evolutionary biologists, and systematists working of algae, fungi, and protozoans. These findings will help to clear the path leading to a better understanding of the ancient diversification of higher organisms.
