通过研究这两个物种在连续分化过程中的基因流动动态，研究组观察到相反的关系：在相同的遗传分化水平上，植物比动物经历更少的基因渗入，这表明物种屏障在植物中建立得更快。这种模式提出了一个问题，即植物和动物之间微观进化过程的差异在宏观进化尺度上影响生殖隔离建立的动态。
据介绍，物种形成，即新的生殖隔离物种从祖先种群中出现的过程，是基因组内基因流动障碍逐渐积累的结果。迄今为止，种间基因交换（基因渗入）在植物物种之间比在动物物种之间发生得更频繁的观点，在科学研究中得到了强有力的支持。

Abstract: Speciation, the process by which new reproductively isolated species emerge from ancestral populations, results from the gradual accumulation of barriers to gene flow within genomes. To date, the notion that interspecific genetic exchange (introgression) occurs more frequently between plant species than animals has gained a strong footing in scientific discourse. By examining the dynamics of gene flow across a continuum of divergence in both kingdoms, we observed the opposite relationship: Plants experience less introgression than animals at the same level of genetic divergence, suggesting that species barriers are established more rapidly in plants. This pattern raises questions about which differences in microevolutionary processes between plants and animals influence the dynamics of reproductive isolation establishment at the macroevolutionary scale.
