Summary of Darwin's theory

本文发表在 rolia.net 枫下论坛Darwin's theory of evolution is based on key facts and the inferences drawn from them, which biologist Ernst Mayr summarised as follows:

Every species is fertile enough that if all offspring survived to reproduce the population would grow (fact).
Despite periodic fluctuations, populations remain roughly the same size (fact).
Resources such as food are limited and are relatively stable over time (fact).
A struggle for survival ensues (inference).
Individuals in a population vary significantly from one another (fact).
Much of this variation is inheritable (fact).
Individuals less suited to the environment are less likely to survive and less likely to reproduce; individuals more suited to the environment are more likely to survive and more likely to reproduce and leave their inheritable traits to future generations, which produces the process of natural selection (inference).
This slowly effected process results in populations changing to adapt to their environments, and ultimately, these variations accumulate over time to form new species (inference).更多精彩文章及讨论,请光临枫下论坛 rolia.net

    • 批达尔文进化论的,真正的靶子在这儿。
    • 从计算机科学的角度看,基因这样的“代码”经过“外力“的不同组合修改可以创造出不同的物种,并非一定由“适应“而产生。
