You should know the difference between artificial selection, natural selection, and evolution. You should be able to explain the differences (and give examples) of directional, stabilizing, and disruptive selection. You should be able to explain the difference (and give examples) of premating and postmating reproductive isolation. You should be able to explain what mechanisms can cause speciation. You should be able to explain the difference between allopatric and sympatric isolation.
