Evolutionary convergence, where similar traits evolve independently in multiple lineages, is a fundamental biological process, which affects many aspects of an organism's morphology. Despite its importance we don't understand what underlies the convergence we observe in nature - does convergence in genetic make-up underlie convergence in morphology? We will investigate whether similar hindlimb morphologies are determined by the same genetic mechanisms in iguanian lizards of Australia and North America. Our study will be the first of its kind in vertebrates and will provide significant information about the evolutionary link between an animal's morphology and its genetic make-up.

进化趋同，即相似的性状在多个谱系中独立进化，是一个基本的生物学过程，它影响生物体形态的许多方面。尽管它的重要性，我们不明白是什么基础上的趋同，我们观察到的性质-趋同的遗传组成的基础上趋同的形态？我们将调查是否相似的后肢形态是由相同的遗传机制在澳大利亚和北美的鬣蜥蜥蜴。我们的研究将是第一个在脊椎动物中进行的此类研究，并将提供有关动物形态与其遗传组成之间进化联系的重要信息。
