Clicker Question• The ability of bacteria to consume nylon must be a

mutation since nylon did not exist until 1940. Inorder to test the theory that the bacteria evolvedfrom non-nylon consuming bacteria a researchergrew non-nylon consuming bacteria with only nylonfor food. Within a few generations the bacteriawere producing the enzyme needed in order todigest nylon.

• What is the adaptation?a) The nylonb) The bacteria which cannot consume the nylonc) The ability to digest nylond) The ability of both the nylon and the non-nylon

consuming bacteria to reproduce

• In the experiment, how are the nylon consuming bacteriamore fit than the non-nylon consuming bacteria?

a) The nylon consuming bacteria are able to survive andreproduce as a result of the adaptation.

• According to this information, what type of reproductivebarrier evolved among the fruit eating birds?

A. Temporal isolationB. Gametic isolationC. Geographic isolationD. Behavioral isolation

A few seed eating birds started to eat fruits. Beak mutationscaused the offspring of these few birds to become better fruiteaters. At the same time a mutation caused a slight change in thefeather coloration of the birds. Over many generations the fruiteating birds preferred to mate only with other fruit eating birds.

• At what point did the fruit eating bird become a new species?A. When it started to eat fruit.B. When feather color changedC. When the fruit eating birds mated only with other fruit eating

birds

A few seed eating birds started to eat fruits. Beak mutationscaused the offspring of these few birds to become better fruiteaters. At the same time a mutation caused a slight change in thefeather coloration of the birds. Over many generations the fruiteating birds preferred to mate only with other fruit eating birds.

• What does this example illustrate?A. The development of marsupials through speciation.B. The evolution of many species from a single

ancestor (adaptive radiation)C. Geographic isolationD. Changes in the gene poolE. All of the above answers are correct

• How did the gene pool for the fruit eating birds change?A. The genes for beak type and feather color changed as a result of

mutations.B. The frequency of the genes for beak type and feather color in the fruit

eating birds increased.C. The genes for the fruit eating birds changed such that the fruit eating birds

became more fit.D. The change in the gene pool for the fruit eating birds resulted in a

beneficial adaptation.E. All of the above answers are correct

Clicker Question• The anteater an the armadillo both have powerful claws

and long sticky tongues which allow them to open thenests of insects such as ants and termites and consumethem. Both of these species are not related. What typeof evolutionary pattern is illustrated by this example?

A. Convergent evolutionB. Divergent evolution

Clicker Question• The kit fox lives in the desert where its coat helps

disguise it from predators. The ears of the kit fox havea greater surface area so that it can more efficientlyremove body heat. The red fox lives in the forest wherethe red coat blends into the surroundings. Geneticanalysis have confirmed that the red fox and the kit foxshare a common ancestor. What type of evolutionarypattern is illustrated by this example?

A. Convergent evolutionB. Divergent evolution

Clicker Question• A forest fire destroys a population of wild flowers. The

Clicker Question• The evolution of the human species has occurred over

millions of years of gradual changes. What type ofmacro evolutionary theory does this illustrate?
