All of the above factors can potentially change over millions of years in a population due to the process of evolution, but the fundamental driving force behind this change is the genetic makeup of the population. Over time, mutations, genetic drift, gene flow, and natural selection can all contribute to changes in the frequencies of different genetic variations within a population, which can then impact various traits such as lifespan, disease resistance, and physical appearance. Ultimately, evolution is a result of changes in the genetic makeup of a population that lead to differences in phenotype and fitness.
