个体的优势常常与群体的利益相冲突，比如当一个等位基因通过减数分裂驱动在一个死亡率增加的群体中传播时，或者当一个无性基因型以牺牲未来的适应性为代价获得即时优势时。种群内的选择可以调和个体和群体的优势，就像在进化过程中“诚实的减数分裂”抵抗分离扭曲，避免“性的代价”。物种之间的选择，其进化的重要性被记录下来，大概有利于物种的生存和繁殖，其遗传系统或社会组织有利于协调个体与群体优势的机制的进化;换句话说，具有遗传或社会系统的物种，其中基因的长期选择优势最接近于其对物种利益的贡献。
An individual''s advantage often conflicts with the good of its group, as when an allele spreads by meiotic drive through a population whose death rate it increases, or when an asexual genotype derives immediate advantage at the expense of future adaptability. Selection within populations may reconcile individual and group advantage, as in the evolution of "honest meioses" resistant to segregation distortion, and the avoidance of the "cost of sex." Selection between species, whose evolutionary importance is documented, presumably favors the survival and multiplication of species whose genetic systems or social organizations favor the evolution of mechanisms reconciling individual with group advantage; in other words, species with genetic or social systems where a gene''s long-term selective advantage most nearly matches its contribution to the good of the species.
