natural selection
the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution
adaption
the process of becoming adapted to an environment; an anatomical, physiological, or behavioral change that improves a population's ability to survive
mutation
a change in the nucleotide-base sequence of a gene or DNA molecule

a relationship between two organisms in which one organism benefits and the other is unaffected
parasitism
a relationship between two species in which one species, the parasite, benefits from the other species, the host, which is harmed
