全球气候的最后一次重大革命是从末次冰期到现在的间冰期的过渡。25-10 ka。植被带和哺乳动物群落经历了重大重组。新的放射性碳数据表明，一系列复杂的气候变化极大地影响了哺乳动物物种的分布范围，但与个别物种的生态有关的方式不同。对于最终灭绝的物种来说，范围的缩小是一个漫长而复杂的地理过程，需要数千年或数万年。最近使用古代DNA进行的遗传学研究表明，这一过程往往伴随着遗传变异的丧失，据推测，还伴随着适应性的丧失。即便如此，一些物种在小型的终极避难所中存活了数千年，最终灭绝--这种模式类似于为濒危的现代生物群假设的“灭绝滞后”或“灭绝债务”。是否避难。物种能否存活并重新扩展到新的区域，特别是在生物干扰的环境中，是由一系列复杂的因素决定的，并非不可避免。引用这篇文章：A.M.

The last major global revolution of climate was the transition from the last glacial stage to the present interglacial, ca. 25-10 ka. Vegetational belts and mammalian communities underwent major reorganisation. New radiocarbon data show that the complex series of climatic changes affected the ranges of mammalian species dramatically, but in differing ways related to the ecologies of individual species. For species that ultimately went extinct, the reduction in range was a prolonged and geographically complex process taking thousands or tens of thousands of years. Recent genetic studies using ancient DNA show that this process was often accompanied by loss of genetic variation and, presumably, adaptive flexibility. Even so, some species survived for thousands of years in small, terminal refugia before finally becoming extinct - a pattern akin to the 'extinction lag' or 'extinction debt' posited for endangered modern taxa. Whether refugial. species can survive to re-expand into new areas, especially in anthropogenically disturbed environments, is determined by a complex of factors and is not inevitable.
