Abstract: Coevolution is the process of reciprocal evolutionary change between interacting species. This process is thought to be a major driver of biological diversification and has been linked to speciation. Coordinated evolution between nuclear and organelle genomes can occur by reciprocal changes in the functional constraints of interacting proteins, and even playing an important role in speciation. In this master's thesis, we used target-capture sequencing data from 122 individuals from two different mitochondrial lineages to test the compensatory evolution hypothesis by comparing the phylogenetic trees of three diferent types of genes: mtDNA, nuclear genes interacting with mitochondrias (oxphos genes) or random nuclear genes. Our results showed the two different mitochondrial lineages. Tajima's D test also showed mitochondria to be under strong purifying selection. However, differences were not observed between the oxphos and the nuclear genes. More studies should be carried out to confirm or not the compensatory evolution hypothesis in this lizard species with the data produced in this study.
