Perhaps the most important is that RNA can, in addition to carrying information, act as a catalyst. ... A catalytic RNA could, potentially, catalyze a chemical reaction to copy itself.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
