Biogeography Quiz

What is biogeography?

• The study of how and why plants and animals live where they do

• The study of rocks and minerals

• The study of weather patterns

• The study of human behavior

Which statement is correct for Peter and Rosemary Grant's study on Darwin's finches done in the 1970s?

• Birds with bigger beaks survived the drought and reproduced

• Birds with smaller beak size survived the drought and reproduced

• After two years of drought, the average beak size had decreased

• The Grant study could prove the evolution of finches by artificial selection

What is adaptive radiation?

• The process of natural selection

• The process of migrating to different places

• The process of adapting to a new environment

What did the study of Darwin's finches by Peter and Rosemary Grant in the 1970s prove?

• Evolution of finches by natural selection

• Decrease in the number of finch species

• No significant changes in the finch population

Which of these is the best definition of biogeography?

• The study of how and why plants and animals live where they do.

• The study of how and why plants affect each other and the environment.

• The study of how and why plants evolve to compensate for changes in habitats.

• None of these are definitions of biogeography.

When looking at camel biogeography it is clear that they evolved adaptations that suited them for the particular environment where they lived. Through natural selection, descendants of the original camel ancestors evolved the diversity they have today.

• true

• false
