The concept of character and the definition of the attribute are two major theoretical issues of phylogenetics. Lately, great progress has been made in the conceptual development of attributes as historical individuals undergoing series of transformations. While operational application of this ideographic concept of character has been possible since the publication of the direct optimization algorithm and POY software, it has been restricted to molecular characters only. The present paper proposes the first application of direct optimization to morphological characters, in the case study of the phylogeny of Odontellidae. This new homology regime is compared to the traditional homology scheme. The theoretical and operational limitations of the application of direct optimization to morphological characters are discussed. Some thoughts on the basics of its generalization to all morphological characters analyzed in a dynamic homology phylogenetic framework are given. © The Willi Hennig Society 2009;.
性状的概念和属性的定义是系统发育学的两个主要理论问题。最近，在将属性概念发展为经历一系列转变的历史个体方面取得了重大进展。自直接优化算法和POY软件发布以来，这种表意性状概念的操作应用虽然可行，但仅限于分子性状。本文提出了直接优化在形态性状上的首次应用，以牙形刺科系统发育的案例研究为例。将这种新的同源性机制与传统的同源性方案进行了比较。讨论了直接优化应用于形态性状的理论和操作局限性。给出了关于将其推广到动态同源性系统发育框架中分析的所有形态性状基础的一些思考。©威利·亨尼希协会2009年。
