Natural selection.
Evolution, as defined by scientists today, is a undirected, purposeless mechanism. So, to answer your question, evolution is not driven by anything.In a sense, evolution is driven by reproductive variation and differential reproductive success. Reproductive variation providing random drift, and differential reproductive success providing a measure of "direction" to this drift.
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
Mendels Law
Behaviors that promote reproductive success are likely to be those that increase an individual's chances of survival, reproductive opportunities, and successful mating. This can include traits such as physical attractiveness, resource acquisition, social status, and mate choice strategies that maximize the chances of producing healthy offspring.
