Unit 9 Evolution Review

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

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

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

What do we call a change in a species over time?

• Adaptation

• Evolution

• Extinction

• Environmental influences

Comparing human hemoglobin of chimpanzees, horses, kangaroos, and chickens, reveal that humans have the fewest amino acid differences with 

• Kangaroos
• Horses
• chickens
• chimpanzees

Both bats and butterflies can fly, yet the anatomy of their wings are vastly different. The two species do not have a recent common ancestor, yet have similar traits. This is an example of what kind of evolution?

• Divergent Evolution

• Convergent Evolution

• Adaptive Radiation

The image shows two peppered months on a tree. In the context of natural selection, would the black colored moth trait be selected FOR or AGAINST?

• Selected FOR

• Selected AGAINST

All the individuals of a species that live in a particular area are called a

• variation
• population
• fossil
• group

Which structure is shown in the picture (different structure, same function)?

• analogous structure

• homologous structure

• vestigial structure

• DNA

What is the purpose of a cladogram?

• To map the ancestral relationships and shared traits of different organisms.

• To trace the inherited traits of a single species over time.

• To check the likelihood of an offspring having a particular trait.

• To monitor mutations that arise among different populations.
