The variation of positive selective pressures from initial positive selection to eventual purifying selection not only represents the adaptive evolution of S protein from animals to human, but also provides a good clue to investigate the interspecies transmission of other viruses.

从最初的阳性选择到最后的负选择，S蛋白经历了变化的自然选择压力。这种变化的选择压力不仅反映了SARS-CoV由动物向人类跨种传播的适应性进化过程，也为研究其他病毒的跨种传播机制提供重要线索。
