寄生虫及其宿主协同进化的研究进展

Status and prospect for researching coevolution of parasite and host

本文对寄生虫及其宿主协同进化的研究进行了回顾,将其发展分为三个阶段:1.寄生虫-宿主协同进化的初步认识;2.协同进化模式及其内在机制的探索;3.协同进化机制研究方法的发展。目前的研究主要集中于协同进化生物学意义的进一步深入探讨。同时,对协同进化的有关概念、方法和本学科的发展进行了简单阐述和讨论。

Three phases can be recognized in the development of the coevolutionary research program:1.Recognition of predictable associations among hosts and their parasites; 2.Search for patterns of association and their underling causes;3.Development of objective and repeatable methods for reconstructing and interpreting these patterns of association.Now, modern research mainly concentrates and expands on the interpretation of the biological questions associated with coevolution-how and why it happened? This paper also gives the method of Brooks parsimony analysis (BPA) , and discusses several questions of coevolution.
