群体选择理论是说：进化可以通过生命体整个群体的生存能力差异来产生，而不是个体的生存差异。 这一理论之所以被否定是因为从数学上看它不太可信。
The idea that evolution can work by the differential survival of entire groups of organisms, rather than just of individuals, was rejected because it is mathematically implausible.
群体选择理论对此提出了一个解释，即尽管由于利他者相对于利己者处于不利的位置，利他者在每一个群体中的频率都会下降，但利他者在总体中的频率却有可能上升。
The theory of group selection proposed an explanation-even if the frequency of altruists is decreasing in every group of a deme, it can still increase in the whole population.
按照的他的理论，进化是群体的结果而不是个体的选择。
According to his theory, evolution is the result of the population and not the single individual.
