Evolution Review

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.

Natural selection is when ____________ decides who survives and who doesn't

• nature
• humans
• animals
• years

• Neither will be successful

What type of structures are these?

• homologous

Whales are aquatic mammals that contain a pelvis (hip) bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)
