Cold adaptation

Since Darwin, researchers have explored how species adapt to different elevations. Tropical reptiles, typically diverse in warm lowlands, have also colonized high elevations on islands and the mainland. The frequency of such transitions has been unclear.自达尔文时代起，研究者便一直在探索物种如何适应不同海拔环境。热带爬行动物通常在温暖低地具有极高的物种多样性，它们同样成功拓殖了岛屿与大陆的高海拔区域。不过这类演化过渡事件的发生频率此前仍未明确。
