Answer
Variation: All life forms vary genetically within a population.
Inheritance: Genetic traits are inherited from parents and are passed on to offspring.
Selection: Organisms with traits that are favorable to their survival and reproduction are more likely to pass on their genes to the next generation.
Time: Evolutionary change can happen in a few generations, but major change, such as speciation, often takes many thousands of generations.
