Genetic algorithms mimic Darwinian natural selection, where "fitness" selects individuals for survival, breeding, and, hence, adaptive mutation.
遗传算法模仿达尔文的自然选择，其中“适应性”选择进行生存、繁殖以及由此而来的适应性变异的个体。
Each additional human case increases opportunities for the virus to improve its transmissibility, through either adaptive mutation or reassortment.
每增加一例人间病例增强了该病毒通过适应性突变或重组提高其可传播性的机会。
The second mechanism is a more gradual process of adaptive mutation, whereby the capability of the virus to bind to human cells increases during subsequent infections of humans.
第二种机制是一个渐进的适应性变异过程，在这一过程中，伴随人类受到感染，病毒与人体细胞相结合的能力增加了。
