This project aims to investigate the origin of paired appendages, a major event in early vertebrate history that changed ecological opportunity and fuelled the radiation of jawed vertebrates. This project expects to generate new knowledge on the mechanism that drove this innovation, which despite over a century of debate, remains one of the great unknowns of comparative vertebrate evolution. Expected outcomes of this project include uncovering the anatomical changes underpinning the origin of the vertebrate appendicular system. This should provide significant benefits as it will inform our own natural history and provide a paradigm for studying gene network conservation, phylogenetic modifications, and the acquisition of novel structures.

这个项目的目的是调查成对附肢的起源，这是早期脊椎动物历史上的一个重大事件，改变了生态机会，并加剧了有颌脊椎动物的辐射。该项目预计将产生关于推动这一创新的机制的新知识，尽管经过了世纪的争论， 关于脊椎动物进化的未知数该项目的预期成果包括揭示支撑脊椎动物无脊椎系统起源的解剖学变化。这应该提供显着的好处，因为它将告知我们自己的自然历史，并为研究基因网络提供一个范例 保护、系统发育修饰和新结构的获得。
