9707146 MCHUGH The symposium ORelationships of Metazoan Phyla: Advances, Problems, and ApproachesO, to be coordinated by Damhnait McHugh and Kenneth M. Halanych, will be hosted by the Society for Integrative and Comparative Biology in Boston in January, 1998. This symposium will provide a critical assessment of the current state of knowledge about the historical (phylogenetic) relationships among the phyla of animals, especially those that have different body plans. By identifying problems and highlighting different approaches to reconstructing the phylogenetic relationships among animal groups, the symposium will play an important role in directing future research in the field. The two-day schedule includes three keynote addresses and 17 symposium presentations from researchers on topics such as the use of mitochondrial gene arrangements to analyze relationships among animals, the genetic basis for change in animal body plans, the phylogenetic relationships among bilaterally symmetrical animals as assessed by both morphological and molecular evidence, and the possibility that the great increase in the numbers of animal taxa observed in Cambrian-age fossils relative to those in older rocks does not mean that there were fewer animal species before the Cambrian. Symposium proceedings will be published in the journal OAmerican ZoologistO.

9707146麦克休关于后生动物的关系：进展、问题和方法的研讨会，由达姆纳伊特·麦克休和肯尼斯·M·哈兰奇协调，将于1998年1月在波士顿由综合与比较生物学学会主办。本次研讨会将对动物门之间的历史(系统发生)关系的知识现状进行关键评估，特别是那些具有不同身体计划的动物。通过发现问题并突出不同的方法来重建动物群体之间的系统发育关系，研讨会将在指导该领域未来的研究方面发挥重要作用。为期两天的日程安排包括三次主旨演讲和17次研讨会演讲，研究人员就以下主题发表了演讲：使用线粒体基因排列来分析动物之间的关系；动物身体结构变化的遗传基础；通过形态和分子证据评估的两侧对称动物之间的系统发育关系；以及在寒武纪化石中观察到的动物类群数量相对于较老岩石中的动物类群数量大幅增加的可能性，并不意味着寒武纪之前动物物种的数量较少。研讨会记录将发表在《OAmerican ZoologistO》杂志上。
