Evolution Review

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals
• They live in similar environments
• They have a common ancestor
• All organisms resemble humans

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.

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

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age
  
• Fossil B is older than fossil C
• Fossils A is older than fossil B
• Fossil D is older than fossil C

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)

• vestigial structure

• analogous structure

• homologous structure

Which one does not increase variation?

• Gene flow

• Migration

• Mitosis

• Crossing Over

I will review how to read a phylogenetic tree!

• Yes

• No

• Maybe

What do phylogenetic trees do?

• Help you visualize how species are related.
• Provide windbreaks in your yard.
• Provide DNA details.
• Show the distribution of organisms
