摘要
作者提出应创建一门源于进化生物学与细胞生物学两者的交叉学科一进化细胞生物学(细胞的进化生物学)。其根本任务在于用进化的观点考察真核细胞的一切方面,从它们的起源和演化来认识它们的现在。文中列举了其具体的研究内容,并分析了其研究方法上的特点,指出在这里需要把进化生物学的综合性分析与细胞生物学的实验研究最紧密地结合起来。文中还论述了真核细胞的细胞器的“不进化”现象,指出其根本原因在于进化焦点的转移。
The author suggests to found a new scientific branch-evolutionary
cell biology, which is an overlapping part of evolutionary biology and cell biology. The main subject of this new scientific branch is to study the origin and evolution of eukaryotic cells and their various living activities in order to examine them from the standpoint of how they arose in history and what principle stages they passed through in their development, and from the standpoint of their developments, to examine what they have become today.
The content of evolutionary cell biology can be temporarily definded as the following. 1. the prokaryotic ancestor of eukarvotes; 2. the origin and evolution of eukaryotic cells and their organelles; 3. the origin and evolution of various activities of eukaryotic cells and their organellesj 4. the origin and evolution of the social relationships among cells; 5. the motive force in the origin and evolution of eukaryotic cells; 6. the 'un-evolution' phenomena of organelles; 7. the law and conditions on transforming endocytosymbionts into cellular organelles; 8. the origin and evolution of the special organelles in certain eukaryotes (e. g. the macronucleus in ciliates, the kinetoplast in kinetoplastid flagellates).
For studying the problems of evolutionary cell biology, both synthetical analyses of evlutionary biology and experimental researches of cell biology are necessary and ought to be integrated with each other.
The main cause of the 'un-evolution' phenomena of cellular organelles and the author regarded that these phenomena were mainly induced by the transference of the focal point of evolution.
