Unit 6A Review

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

What characteristic did Darwin observe about the finches on the Galapagos Islands?

• Their feathers 
• Genotypes 
• Their beaks
• Their body sizes

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 environment around Manchester, England, changed during the Industrial Revolution.  How did this change affect peppered moths living in the area?

• Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.
• Natural selection favored moths with white wings that were easy for predators to see.
• Natural selection favored moths with white wings because predators could not see them on the soot-colored trees.
• Natural selection caused moths with white wings to become extinct.

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

Which statement is part of Darwin’s theory of evolution by natural selection? 

• More offspring are produced than can possibly survive.
• The organisms that are the fittest are always largest and strongest. 
• The number of offspring is not related to fitness.
• Acquired characteristics that are inherited are the cause of evolution.

A change in a DNA sequence that affects genetic information

• mutation

• fitness

• transformation

Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches 
 

• have the ability to interbreed.
  have the ability to interbreed.
• acquired traits through use and disuse.
• all eat the same type of food.
• descended from a common ancestor.

Images of the embryo and adult stages of three different organisms are shown.

Which of the following is the best conclusion that can be drawn from this evidence?

• Having similar embryos indicates that these organisms eat the same types of food.

• Having similar embryos indicates that these organisms live in a similar environment.

• Having similar embryos indicates that these organisms share a recent common ancestor.

• Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
