同源是一种生物上的相同关系,据称在面对形式、组成和功能的变化时保持不变。尽管同源性具有中心性和重要性,但对于我们应该如何理解这一概念,人们并没有达成共识。两种主要的同源性观点--系谱和发育记述--都有明显的缺陷。我们提出了一个新的帐户,同调的层次依赖帐户,它避免了这些缺点。此外,我们的帐户提供了特殊的、一般的和系列同调之间的连续性。
Homology is a biological sameness relation that is purported to hold in the face of changes in form, composition, and function. In spite of the centrality and importance of homology, there is no consensus on how we should understand this concept. The two leading views of homology, the genealogical and developmental accounts, have significant shortcomings. We propose a new account, the hierarchical-dependency account of homology, which avoids these shortcomings. Furthermore, our account provides for continuity between special, general, and serial homology.
