Evidence of Evolution 1

Multiple Choice

How did Darwin's observations of finches differ among the Galapagos Islands?

• They did not differ; all finches were the same

• Finches on different islands had different dietary habits

• Finches on different islands had differently shaped beaks suited to their specific diets

• Only the color of the finches differed

Multiple Choice

These birds live close together and look similar. However, they do not reproduce together because one population has a courting dance to attract mates and the other does a pointing display.

Are they the same species?

• no because they do not interbreed

• yes because they live in the same place

• yes because they look alike

• not enough information

Open Ended

Propose a method to study the effect of urbanization on the biodiversity of a nearby forest.

Multiple Choice

variation

• random and irreversible changes in the DNA of an organism

• the individuals in a population that are best suited to the environment and will leave more offspring than those which are not

• mating which is the result of certain individuals selecting a mate based on phenotype

• the differences in the genetic makeup of organisms within a gene pool

Multiple Choice

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the genetic material (DNA) of the sexually reproducing organism to -

• contain fewer mutations
• be lesser in quantity
• be simpler overall
• show more variation

Multiple Choice

Jon states the following claim: "Biogeography provides evidence for the theory of evolution." To support this claim, which evidence would be MOST useful for Jon to cite?

• A sequence of fossils shows that horses became smaller over time.

• Polar bears and grizzly bears are similar in many ways, but are adapted to live in different regions.

• Farm crops developed in Asia are now raised successfully in regions all over the world.

• Fossils of plants and animals have been found in Antarctica, which now is covered in ice.

Multiple Choice
