This project aims to investigate the developmental basis of vertebrate appendage diversity and how during evolution limbs became fins. The project expects to determine how specific populations of cells that regulate fin formation arise during development, the genetic basis of their function, and how their role in development has evolved in lineages with divergent appendage anatomy. Expected outcomes include understanding the molecular basis of the fin-limb transition and the origin of divergent appendage patterning systems. This should provide significant benefits by advancing our knowledge of the relationship between evolution and development, and understanding limb defects, which are amongst the most common of human congenital malformations.

本项目旨在探讨脊椎动物附属物多样性的发育基础，以及在进化过程中四肢如何变成鳍。该项目希望确定在发育过程中调节鳍形成的特定细胞群是如何产生的，它们功能的遗传基础，以及它们在具有不同附属物解剖结构的谱系中在发育中的作用是如何演变的。预期的结果包括了解鳍肢转变的分子基础和不同附属物模式系统的起源。这将通过提高我们对进化和发育之间关系的认识，以及对肢体缺陷的理解提供重大的好处，肢体缺陷是人类最常见的先天性畸形之一。
