脊椎动物的颅基板对脊椎动物的颅部感觉器官至关重要。它们的进化起源引起了进化生物学家和发育生物学家的广泛关注，产生了关于它们在其他谱系中的假定同源物以及可能构成其起源和多样化的发育和遗传创新的推测和假说。在本文中，我们首先简要回顾我们目前对基板发育以及它们所形成的细胞类型和结构的理解。接下来，我们总结先前关于基板进化的假说，讨论它们的优点和注意事项，然后考虑从基板发育而来的各种细胞类型的进化历史。在一篇相关综述中，我们还进一步考虑外胚层模式形成的进化。利用来自脊椎动物、被囊动物、文昌鱼、其他两侧对称动物和刺胞动物的数据，我们将这些线索构建成一个基板进化历史以及构成基板进化和发育基础的基因、细胞和发育过程的情景。（C）2014爱思唯尔公司。保留所有权利。
Vertebrate cranial placodes are crucial contributors to the vertebrate cranial sensory apparatus. Their evolutionary origin has attracted much attention from evolutionary and developmental biologists, yielding speculation and hypotheses concerning their putative homologues in other lineages and the developmental and genetic innovations that might have underlain their origin and diversification. In this article we first briefly review our current understanding of placode development and the cell types and structures they form. We next summarise previous hypotheses of placode evolution, discussing their strengths and caveats, before considering the evolutionary history of the various cell types that develop from placodes. In an accompanying review, we also further consider the evolution of ectodermal patterning. Drawing on data from vertebrates, tunicates, amphioxus, other bilaterians and cnidarians, we build these strands into a scenario of placode evolutionary history and of the genes, cells and developmental processes that underlie placode evolution and development.
