Crash Course Evolution Quiz

What is the theory of evolution?

• A guess about the origin of life

• A hunch about gene distribution

• A large set of ideas that explains many observations

• A hypothesis about natural selection

What is the fossil record evidence of?

• The change in gene distribution over time

• The extinction of ancient organisms

• The similarity of all living organisms

• The distribution of species around the world

What do homologous structures in different organisms suggest?

• They are evidence of a common ancestor

• They are the result of random mutations

• They are unrelated to each other

• They are unique to each species

What do DNA sequences in different species indicate?

• They are completely different in each species

• They are not useful for evolutionary studies

• They are unrelated to each other

• They are 98.6% identical in humans and chimpanzees

What does biogeography explain about the distribution of species?

• It has no relevance to the theory of evolution

• It demonstrates the impact of continental drift on species distribution

• It shows that similar species are found in different regions

• It explains the random distribution of species around the world

What is an example of direct observation of microevolution?

• The resistance of bacteria to antibiotics

• The discovery of new species of finches in the Galapagos islands

• The change in digestive systems of mosquitos due to DDT

• The development of muscles in Italian wall lizards

What is macroevolution?

• The development of new species in a short time period

• The long-term evolution of large organisms

• The rapid evolution of small populations

• The change in gene distribution over time

What did the study of dinosaur fossils in the 1820s reveal?

• Dinosaurs were similar to modern reptiles

• Dinosaurs were not related to modern organisms

• All dinosaurs were giant iguanas

• Dinosaurs had diverse characteristics

What did the study of whale fossils reveal about their evolution?

• Whales are not related to any other organisms

• Whales have no relation to other mammals

• Whales evolved from land mammals

• Whales are a separate group of organisms

What did the study of marsupials' distribution reveal about their evolution?

• Marsupials in Australia are descendants of those in South America

• Marsupials are evenly distributed around the world

• Marsupials in Australia are descendants of those in North America

• Marsupials evolved independently in different regions
