Evidence for Evolution Quiz

What are the two bold claims made by the theory of Biological Evolution?

• All living things on earth are related and evolved from a common ancestor, powered by natural processes.

• All living things have unique origins and processes.

• Evolution is a random process without any scientific evidence.

• Only certain species have evolved over time, while others have remained unchanged.

Which group of animals is used to focus on the evolutionary tree in the video?

• Birds

• Reptiles

• Cetaceans

• Insects

What does comparative anatomy reveal about whales?

• They lay eggs.

• They share anatomical features with land mammals.

• They are cold-blooded.

• They have gills like fish.

What does the presence of tiny hip and leg bones in modern whales suggest?

• Evidence of aquatic origin with no land ancestors

• A recent adaptation for swimming

• A coincidence with no evolutionary significance

• Remnants from their evolutionary history as land mammals

What does embryology show about the development of whales?

• Whale embryos develop gills at early stages.

• Whale embryos show leg buds that disappear as they grow.

• Whale embryos develop feathers.

• Whale embryos are identical to fish embryos.

What is significant about the basilosaurid whales according to the fossil record?

• They were fully aquatic with no leg structures.

• They had fully developed legs for walking on land.

• They show an intermediate nasal placement, supporting evolution.

• They are identical to modern whales.

What role do fossils play in understanding evolution?

• They provide a record of ancient shopping habits.

• They only show that dinosaurs existed.

• They show the transition of species over time, supporting evolutionary theory.

• Fossils are unrelated to the study of evolution.

How do scientists use DNA to study evolution?

• By altering the DNA of living species

• By comparing the DNA of fossils

• By comparing the DNA code of different living creatures

• DNA is not used in studying evolution

What does the DNA evidence suggest about the relationship between whales and hippos?

• Whales and hippos share no common ancestors.

• Whales and hippos evolved from a common ancestor.

• Whales evolved directly from hippos.

• DNA evidence is inconclusive about the relationship.

Which feature is shared by both whales and hippos?

• Gills for breathing underwater

• Feathers for insulation
