Evidence for Evolution Quiz

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

• Evolution is a random process without any natural selection.

• Living things do not evolve over time.

• All living things on earth evolved from a common ancestor.

• All living things have a fixed genetic code.

Which branch of the evolutionary tree is focused on in the video to demonstrate evolution?

• Reptiles

• Amphibians

• Cetaceans

• Birds

What is comparative anatomy?

• The study of animal behavior in different environments.

• The study of human anatomy only.

• The study of bone structures in mammals.

• The study of similarities and differences in the anatomy of different organisms.

How do whales breathe?

• They do not need to breathe

• Using lungs like land mammals

• Through gills like fish

• Through their skin

What embryological evidence supports the idea that whales evolved from land mammals?

• Whale embryos have gills at early stages.

• Whale embryos are identical to fish embryos.

• Whale embryos show development of leg buds that later disappear.

• There is no embryological evidence supporting this idea.

What role does embryology play in studying evolution?

• Embryology has no role in evolutionary studies.

• It reveals similarities in the developmental stages of different species, supporting common ancestry.

• It shows how embryos of different species are completely distinct.

• It provides evidence of how traits are inherited from parents.

What does the fossil record of basilosaurid whales suggest?

• They were identical to modern whales.

• They were fully aquatic with no leg structures.

• They show no evolutionary link to land mammals.

• They had small, yet fully developed hips and leg bones.

How do scientists use fossils to understand evolutionary history?

• Fossils are not used in studying evolution.

• By dating them to create a timeline of life.

• By showing that fossils have not changed over millions of years.

• By comparing them to modern animals to find no similarities.

What is the significance of Maiacetus in whale evolution?

• It is a modern whale with no terrestrial features.

• It shows no evolutionary changes over time.

• It is considered a walking whale, linking aquatic and terrestrial life.

• It disproves the theory of evolution.

How is DNA evidence used to support the theory of evolution?

• By showing that all living things have identical DNA.

• By comparing the DNA of different species to find common ancestors.

• By demonstrating that DNA is unique to each species with no similarities.

• By proving that DNA does not change over time.
