Computer experiments that mirror the evolutionary dynamics of sexual and asexual organisms as they occur in nature were used to test features proposed to explain the evolution of sexual recombination. Results show that this evolution is better described as a network of interactions between possible sexual forms, including diploidy, thelytoky, facultative sex, assortation, bisexuality, and division of labor between the sexes, rather than a simple transition from parthenogenesis to sexual recombination. Diploidy was shown to be fundamental for the evolution of sex; bisexual reproduction emerged only among anisogamic diploids with a synergistic division of reproductive labor; and facultative sex was more likely to evolve among haploids practicing assortative mating. Looking at the evolution of sex as a complex system through individual-based simulations explains better the diversity of sexual strategies known to exist in nature, compared to classical analytical models.

生殖分工和遗传复杂性的协同作用推动了性别的进化

反映有性和无性生物在自然界发生时的进化动力学的计算机实验被用来测试被提议用来解释性重组进化的特征。结果表明，这种进化被更好地描述为可能的性形式之间的相互作用网络，包括二倍体、孤雌生殖、兼性、分类、双性恋和两性之间的分工，而不是从孤雌生殖到性重组的简单过渡。二倍体被证明是性别进化的基础。双性生殖只出现在具有协同生殖劳动分工的异配二倍体中；并且兼性在实行混合交配的单倍体中更有可能进化。
