Abstract

I suggest a common population genetic mechanism that explains persistence of biological species as consistently reproducing groups of similar organisms: genetic renewal due to genetic drift or selection, which restricts genetic diversity of populations. In contrast to concepts explaining species integrity via interbreeding, the concept of drift- and selection-induced genetic renewal explains species existence not only for sexually reproducing organisms, but also for asexual, or agamous, organisms. I redefine concepts of population, isolation and species in terms of genetic renewal. The proposed concept of renewing species develops Alan Templeton’s cohesion species concept.

摘要

我建议一种共同的种群遗传机制，该机制可以解释生物物种的持续存在，因为它们始终是相似生物体的繁殖群体：由于遗传漂移或选择而导致的遗传更新，这限制了种群的遗传多样性。与通过杂交解释物种完整性的概念相反，漂移和选择诱导的遗传更新的概念不仅解释了物种的存在，不仅存在于有性繁殖的生物中，而且还存在于无性或无性的生物中。我从遗传更新的角度重新定义了种群，隔离和物种的概念。提出的物种更新概念发展了艾伦·邓普顿的凝聚物种概念。
