The ultimate goal of the proposal is to explain evolution. This is not an easy task considering the stunning diversity in biological populations and their complex interactions with the environment. Long-term evolution can be more easily studied in small populations for which it is reasonable to assume that mutants are going to extinction or fixation by random drift one at a time. Then, the effect of selection on the probability of fixation becomes of prime importance. Approximations for this probability have to be ascertained and conditions for selection to favor one type replacing another deduced and interpreted.

该提案的最终目的是解释进化论。 考虑到生物种群惊人的多样性及其与环境的复杂相互作用，这不是一项容易的任务。 在小种群中研究长期进化更容易，因为可以合理地假设突变体会通过随机漂移一次一个地灭绝或固定。 然后，选择对注视概率的影响就变得至关重要。必须确定该概率的近似值，并推导和解释有利于一种类型取代另一种类型的选择条件。
