QUESTION: What is evolution? As it is most famously used, evolution is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state.
Evolution is the change in heritable traits within populations over time. Often the definition is more focused to mean changing allele frequency within a population over time. Selection (including sexual, kin, etc) is one way that allele frequencies can change and it is the only mechanism that produces adaptation.
