a.) each species produces many more offspring than can survive long enough to reproduce.
b.) the offspring that do survive contain genes that are inherited from the parents.
c.) some individuals have genes that increase their chances for survival and reproduction. these individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
d.)living organisms change over time.
e.)there is a struggle for existence among the members of a population.
f.)there is variation among the members of a species. some of this variation is genetically determined and so can be passed on to future generations.
