10. What is the Red Queen hypothesis in evolutionary ecology?
(A) A hypothesis about the formation of new species
(B) A hypothesis stating that organisms must constantly evolve to maintain relative fitness in a changing environment
(C) A hypothesis about gene flow
(D) A hypothesis about genetic drift

11. How do ecological gradients such as temperature or altitude influence animal evolution?
(A) By promoting gene flow
(B) By decreasing species competition

15. What is convergent evolution?
(A) The study of animal anatomy
(B) The evolution of new species
(C) The evolution of similar traits in unrelated species due to shared environmental pressures
