• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

Due to pollution, a pond becomes darker over time. Which trait variation became more common?

• light fish

• dark fish

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

According to natural selection, light colored tree trunks would favor
