• These are the same animal.
• These animals have a common ancestor.
• These animals are not likely related.
• These animals are likely becoming one species.

Which two organisms are the most closely related according to their DNA sequence?
Critter A--> ATG CTT AAC CCG TTA
Critter B--> ATC GTT TTC CCG TAA
Critter C--> ATG CTA TAG GCG TAA

• Critter A and B
• Critter A and C
• Critter B and C
• They are all equally related

Individuals who are considered fit, have:

• Stronger genes
• Fewer mutations
• More food
• More offspring

The process by which organisms with variations most suited to their local environment survive and leave more offspring.

• Natural Selection
• Artificial Selection
• Speciation
• Genetic Drift

What does evolution mean?

• To change something
• To change and adapt over time
• To lose some original features
• To improve ssomething over time

What is natural selection?

• Your natural fate is decided from birth
• Nature actively chooses who surivives
• Those best suited to demands of environment surivie
• The weakest of a species surivie
