Theoreticians have long recognised the value of colour polymorphic systems for providing a window into the evolution of genetic diversity, adaptations and even speciation. However, few species display appropriate discrete polymorphisms, and as such, there is little empirical evidence to support these ideas. Using a series of innovative experiments and a unique bird displaying three discrete head colours, I will test these theories, producing results which will have a major international impact. Understanding the interaction of environmental and genetic diversity in the highly endangered Gouldian finch also offers an opportunity to provide insight into how declining wild populations can be effectively managed.

理论家们早就认识到颜色多态系统的价值，它为遗传多样性、适应性甚至物种形成的进化提供了一个窗口。然而，很少有物种显示适当的离散多态性，因此，几乎没有经验证据支持这些想法。通过一系列创新的实验和一只独特的鸟展示三种不同的头色，我将测试这些理论，产生将产生重大国际影响的结果。了解环境和遗传多样性的相互作用，在高度濒危的胡锦雀也提供了一个机会，提供洞察如何减少野生种群可以有效地管理。
