the process where organisms that have the best adapted traits for their environment survive and reproduce to pass those traits to future generations

traits are inherited from parents

natural-made selection process

human-made selection process

a rapid process

allows only selected traits to be inherited over generations

allows only beneficial traits to be inherited over generations

change occurs over many generations

examples: breeds of dogs and increased kernels in corm

the identification and breeding by humans of desirable traits in plant and animals

examples: beaks in finches and long necks in giraffes

occurs in natural populations

a slow process
