remember the essential requirements for selection with the handy acronym V.I.S.T


V = Variation: All life forms vary genetically within a population. It is this genetic variation upon which selection works.

I = Inheritance: Genetic traits are inherited from parents and are passed on to offspring.

S = Selection: Organisms with traits that are favorable to their survival get to live and pass on their genes to the next generation.

T = Time: Evolution takes time. Evolution can happen in a few generations, but major change, such as speciation, often takes long periods of time.
