MacLean Submitted for the degree of Doctor of Philosophy Institute of Evolutionary Biology University of Edinburgh 2019 Declaration The composition of and work contained within this thesis is my own work, except where explicitly stated otherwise. Oscar A. MacLean i Abstract Plasmodium is the genus responsible for causing malaria in humans, killing more than 400,000 individuals a year. Species from the genus are also capable of infecting different primate, avian and rodent species. In this thesis I use previously published genomic data to investigate several aspects of Plasmodium evolution. I compare mutation rates and the strength of selective constraint across different subgenera of Plasmodium. I find little to no conservation of mutation rate across the genus, and no evidence that these mutation rate changes are driven by selective optimisation.
