While the interplay between migration and adaptation dictates species response to climate change, technological limitations have obfuscated explicit tests on past adaptive responses. However, a surge in technology-driven advances in paleoecological methods coincides with breakthroughs in processing ancient DNA, providing the first opportunity to assess adaptation to past climate shifts.

古生态学的演变。

虽然迁移和适应之间的相互作用决定了物种对气候变化的反应，但技术限制已经模糊了对过去适应性反应的明确测试。然而，技术驱动的古生态方法进步的激增与处理古代 DNA 的突破相吻合，这为评估对过去气候变化的适应情况提供了第一个机会。
