In this process, better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.
• The acquired traits of a population.
• Hair color and eye color
• Attractive features.

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.

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype
