摘要

这篇论文对传统的系统发育提出了一个问题:通过裂变繁殖的生物体的身份可以用几种不同的方式来理解。这引发了关于如何区分亲本生物和后代的问题，使垂直基因转移变得不清楚。父母和子女之间的区别源于我所说的身份问题。如何解决这个问题对系统发育分组有影响。如果一个特定的无性生物的身份通过裂变而持续存在，那么系统发育树上的垂直谱系将以不同的方式分裂，而如果一个有机体的身份没有在裂变过程中幸存下来。

Asexual organisms, identity and vertical gene transfer

This paper poses a problem for traditional phylogenetics: The identity of organisms that reproduce through fission can be understood in several different ways. This prompts questions about how to differentiate parent organisms from their offspring, making vertical gene transfer unclear. Differentiating between parents and offspring stems from what I call the identity problem. How the problem is resolved has implications for phylogenetic groupings. If the identity of a particular asexual organism persists through fission, the vertical lineage on a phylogenetic tree will split differently than if the identity of an organism does not survive the fission process.

期刊介绍： Studies in History and Philosophy of Biological and Biomedical Sciences is devoted to historical, sociological, philosophical and ethical aspects of the life and environmental sciences, of the sciences of mind and behaviour, and of the medical and biomedical sciences and technologies. Contributions are from a wide range of countries and cultural traditions; we encourage both specialist articles, and articles combining historical, philosophical, and sociological approaches; and we favour works of interest to scientists and medics as well as to specialists in the history, philosophy and sociology of the sciences.
