3 domains: bacteria, Archaea, Eukarya

polymorphism: variation within a population where different structures, colors, biochemistry, etc. but clearly belong to the same population since they reproduce with one another.

Geographic Variation: population in different areas look different from each other.

Hybrid zones: geographic areas where two distinctly different forms of an organism contact each other and interbreed.

Clinal variation: gradual change in some trait across geographic distance.
