了解高山生物是如何在历史环境变化中形成的，可以提高我们预测和减轻全球变暖对高山物种构成的威胁的能力。中新世早期至中期，邻近地区的加速多样化和殖民化可能是由造山和亚洲季风的增强共同驱动的。横断山脉的高山植物群比地球上任何其他高山植物群持续存在的时间都要长得多，这说明了过去的地质和气候事件如何塑造了现代生物群落。
Understanding how alpine biotas formed in response to historical environmental change may improve our ability to predict and mitigate the threats to alpine species posed by global warming. In the world's richest temperate alpine flora, that of the Tibet-Himalaya-Hengduan region, phylogenetic reconstructions of biome and geographic range evolution show that extant lineages emerged by the early Oligocene and diversified first in the Hengduan Mountains. By the early to middle Miocene, accelerated diversification and colonization of adjacent regions were likely driven jointly by mountain building and intensification of the Asian monsoon. The alpine flora of the Hengduan Mountains has continuously existed far longer than any other alpine flora on Earth and illustrates how modern biotas have been shaped by past geological and climatic events.
