Selective Breeding
the process by which individuates that are better adapted to their environment survive and reproduce more successfully than less well adapted individuates do; a theory to explain the mechanism of evolution
Natural Selection
a period between the birth of one generation and the birth of the next generation
Generation Time
the formation of one species as a result of one evolution
