*** 9527453 Newman The fields of developmental and evolutionary biology are both undergoing ferment. The vast progress in the last few years in characterizing the genetic mechanisms involved in embryonic development has demonstrated unexpected degrees of functional redundancy and overdetermination in these processes. In addition, evolutionary studies have revealed surprising extents of homoplasy and other forms of parallel morphological evolution in disparate lineages, as well as evidence that extensive morphological diversity appeared much earlier in the history of multicellular life than previously thought. These phenomena have raised new questions concerning the relationship between gene activity and the generation of biological form, and have suggested to some that the solution to these puzzles will emerge with the development of a new parardigm for understanding the evolution of developmental systems. It is the purpose of this symposium on "Determinants of Morphological Evolution" to bring together investigators in the areas of developmental and evolutionary biology whose work evidences an appreciation of the connection between these disciplines, and physical scientists working in the areas of morphogenesis of condensed materials, to discuss questions of the genetic, epigenetic, physical and life history determinants of the evolution of biological form. The invitation by the organizers of the Fifth International Congress of Systematic and Evolutionary Biology to present a symposium on these subjects represents an encouragement to such interdisciplinary activity, and the site of this meeting, in Hungary, will help foster communication among groups of scientists with traditionally different approaches to the study of biological form. ***

纽曼 发育生物学和进化生物学领域都在酝酿之中。在过去的几年里，在表征胚胎发育中所涉及的遗传机制方面取得了巨大的进展，这表明这些过程中存在意想不到的功能冗余和过度决定。此外，进化研究揭示了不同谱系中惊人程度的同质性和其他形式的平行形态进化，以及广泛的形态多样性在多细胞生命历史中出现的证据比以前认为的要早得多。这些现象提出了关于基因活动和生物形式产生之间关系的新问题，并向一些人表明，随着理解发育系统进化的新范式的发展，这些难题的解决方案将出现。这是本次研讨会的目的“形态进化的决定因素”汇集研究人员在发展和进化生物学领域的工作证明了这些学科之间的连接的赞赏，和物理科学家在凝聚材料的形态发生领域的工作，讨论问题的遗传，表观遗传，物理和生活史的生物形式的进化的决定因素。第五届国际系统和进化生物学大会的组织者邀请举办一次关于这些主题的专题讨论会，这是对这种跨学科活动的鼓励，这次会议在匈牙利举行，将有助于促进对生物形式研究采取传统上不同方法的科学家群体之间的交流。 ***
