• get smaller animals

• create animals with desirable traits

• create animals with bad traits

The following is a similarity between artificial selection and natural selection

• Humans determine traits

• Nature determines traits

• Offspring are produced

When nature selects and species with beneficial adaptation survive and produce offspring

• natural selection

• artificial selection

Artificial Selection decreases diversity which is bad because

• organisms with same traits will refuse to reproduce with each other

• organisms with all the same traits are susceptible to extinction.

• organisms with the same traits will be very aggressive

• organisms with same traits collectively get smarter and will some day rule the world
