参考答案: Mutations are the source of variation.
Mutations lead to characteristics that may be advantageous to the individual or harmful, (orneutral). Advantageous mutations passed on to offspring can give an improved chance of survival.
Better survival leads to an increase of the new allele frequency in the population.
Evolution by natural selection selects for the advantageous alleles.
