Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unprecedented system, backed by 37 years of long term host-parasite and behavioural data, and recent genetic analyses. This project intends to produce significant data to allow an examination of the early stages of host-parasite evolution in action, providing novel insights into the speciation process.

寄生虫被认为是种群分化和最终物种形成的驱动因素，但这一过程的动力学还没有得到很好的理解。该项目将利用新的基因组技术，新的杂交区分析和择偶数据，研究寄生虫通过与沉睡的蜥蜴Tiliqua rugosa中的免疫反应基因相互作用来驱动种群分化的假设。这个物种提供了一个前所未有的系统，由37年的长期宿主-寄生虫和行为数据以及最近的遗传分析支持。该项目旨在产生重要的数据，以检查宿主-寄生虫进化的早期阶段，为物种形成过程提供新的见解。
