Croizat, L.、G. Nelson 和 D. E. Rosen（美国自然历史博物馆鱼类学系，纽约，纽约 10024）1974 年。起源中心和相关概念。系统。动物园。 23:265-287.-达尔文意义上的起源中心概念经常被接受和使用，就好像它是历史动物地理学分析所必需和基础的概念模型一样。但在某些方面，它与共同祖先和变异的原则不一致（例如，异域物种形成），并且将其应用于动物分布的具体例子通常会产生模糊的结果。在接下来的几页中，我们对起源中心概念进行了批判，并概述了另一种概念模型，其中涉及生物分布的广义模式（广义轨迹）。我们假设给定的广义轨迹估计了一个祖先生物群，由于地理的变化，该生物群已细分为局部区域的后代生物群。我们假设，在这些地区，由于传播障碍而或多或少地在生物上相互隔离，后代生物群会分化并产生更现代的分类多样性和分布模式。我们拒绝达尔文的起源中心概念及其推论，即物种的扩散，将其作为历史生物地理学中普遍适用的概念模型。我们承认扩散的现实，并详细说明了如何根据同源性和广义轨迹来识别扩散的例子，但我们认为，在全球范围内，现代生物分布的一般特征是由祖先生物群因地理变化而细分所决定的。 [生物地理学；分配;进化。]
Croizat, L., G. Nelson, and D. E. Rosen (Department of Ichthyology, The American Museum of Natural History, New York, New York 10024) 1974. Centers of origin and related concepts. Syst. Zool. 23:265-287.-The concept of center of origin in the Darwinian sense is often accepted and used as if it were a conceptual model necessary and fundamental to historical zoogeographical analysis. But in certain respects it is inconsistent with the principles of common ancestry and vicariance2 (e.g., allopatric speciation), and its application to concrete examples of animal distribution generally yields ambiguous results. In the following pages we present a critique of the concept of center of origin, and outline an alternative conceptual model, involving generalized patterns of biotic distribution (generalized tracks). We assume that a given generalized track estimates an ancestral biota that, because of changing geography, has become subdivided into descendant biotas in localized areas. We assume that in such areas, more or less biotically isolated from one another by barriers to dispersal, the descendant biotas differentiate and produce more modern patterns of taxonomic diversity and distribution. We reject the Darwinian concept of center of origin and its corollary, dispersal of species, as a conceptual model of general applicability in historical biogeography. We admit the reality of dispersal and specify how examples of dispersal may be recognized with reference both to sympatry and to generalized tracks, but we suggest that on a global basis the general features of modern biotic distribution have been determined by subdivision of ancestral biotas in response to changing geography.
