Hybrid zones provide a powerful opportunity to analyze ecological and evolutionary interactions between divergent lineages. As such, research on hybrid zones has played a prominent role in the fields of evolutionary biology and systematics. Herein, we clarify what hybrid zones are, what is (and is not) known about them, and how different types of genomic data contribute to our understanding of hybrid zones. We then review two key topics, namely, what genomic analyses of hybrid zones have revealed about the basis and dynamics of speciation and how hybrid zones directly affect evolutionary processes. In the latter case, we emphasize the importance of contingency and ecological and genomic context in outcomes of hybridization. Throughout, we highlight limitations and key unknowns, and suggest approaches most likely to advance our understanding of hybrid zones and evolutionary processes in general.

来自杂交区的种群基因组数据分析

混合区为分析不同谱系之间的生态和进化相互作用提供了强大的机会。因此，杂交带的研究在进化生物学和系统学领域发挥了重要作用。在此，我们阐明了什么是混合区，它们已知（和未知）什么，以及不同类型的基因组数据如何有助于我们理解混合区。然后我们回顾了两个关键主题，即杂交带的基因组分析揭示了物种形成的基础和动态以及杂交带如何直接影响进化过程。在后一种情况下，我们强调偶然性以及生态和基因组背景在杂交结果中的重要性。在整个过程中，我们强调了局限性和关键的未知数，
