进化新奇物的起源是进化发育生物学研究的中心议题。在任何新的特征中，都有一个保守的组成部分，它要么是结构性的，要么与潜在的遗传控制有关，但什么是真正的新的，什么是保守的，并不总是很明显。然而，解开这种新旧特征的混合是理解进化变化机制的基础。节肢动物附肢的起源说明了追踪进化新奇事物起源的复杂性。在血统的基础上，主体轴已经被分割和前后图案化，并且已经可以获得形成侧向生长所需的遗传工具包。新奇可能是发展的决定，“阅读”可用的轴向信息，并利用它来区分分段模式和轴向分段的附件。一些重要的新办法弥补了传统上被区分为系统性变化和局部性变化之间的差距。例如，几个动物群体进化出的体腔的起源可能是由细胞间粘附特性的简单变化引发的。现有个体发育途径中任何可能的变化都有可能产生新的东西。
The origin of evolutionary novelties is a central topic in evolutionary developmental biology (evo-devo) studies. In any new feature, there is a conserved component that is either structural or related to the underlying genetic control, but it is not always obvious what is really new and what is conserved. Nevertheless, disentangling this blending of old and new features is basic to understanding mechanisms of evolutionary change. The origin of arthropod appendages illustrates the complexity in tracing the origin of evolutionary novelties. At the base of the lineage, the main body axis was already segmented and antero-posteriorly patterned, and the genetic tool kit required to form lateral outgrowths was already available. The novelty was possibly the developmental decision to "read" the available axial information and to exploit it for differentiating segmentally patterned and axially segmented appendages. Some important novelties bridge the gap between what have been traditionally distinguished as systemic and local changes. For example, the origin of the body cavities evolved by several animal groups may have been initiated by simple changes in cell-to-cell adhesive properties. Any possible change in an existing ontogenetic pathway has the potential to generate novelties.
