Evolution by natural selection takes place through the success and failure of individuals to survive and reproduce. It thus involves the lowest level of taxonomic structure — the individual. To understand many of the processes of evolution at higher taxonomic levels, it is necessary to study and understand the behaviour of populations and individuals in nature and the laboratory: to record their survival and measure their fitness. This study of the interaction between individual fitness and genetic variation lies within the field of population genetics.
