Two organisms that are closely related would have

• very similar DNA sequence

• exactly the same DNA sequences

• no proteins in common

• completely different DNA sequence

The law of superposition states

• the oldest rock layer is on the top, the younger rock layer is on the bottom
• rock layers are always in sequence from oldest to youngest
• the youngest rock layer is on the bottom and the oldest is on the top
• the oldest layer is on the bottom and the youngest is on the top when it is undisturbed

Relative dating

• gives the exact age of rocks and fossils
• is when you date your cousin
• gives the approximate age of rocks
• tells us who to trust

Average phenotypes are favored in the environment, while extremes have lower survival rates.

• seasonal selection

• distruptive selection

• directional selection

• stabilizing selection
