Evolution Test Review

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

According to this data, the unknown bacterial species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

Over time, early organisms were ______________ and became more ______________.

• Complex, simple

• Uncommon, common

• Simple, complex

• Younger, older

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? 

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals are better adapted to exist in their environment than others are. 
• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals tend to produce fewer offspring than others in the same environment.

Several of the Galapagos Islands are inhabited by grasshoppers, beetles, flies, bees, and butterflies. Finches that feed on these consumers would have beaks adapted for

• probing, only

• probing or grasping

• crushing or probing

• parrotlike feeding or grasping

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.

What genetic event causes different beak sizes to first arise?

• They arose because of their need to be able to eat different food.

• Random mutations

• The environment made the change happen.

• The finches beaks changed a little at a time each generation.
