Evidence for Evolution Quiz

The video explores five major categories of evidence for evolution: the fossil record, comparative anatomy, comparative embryology, DNA and biochemistry, and geographic distribution. It explains how fossils show changes over time, anatomical similarities suggest common ancestry, embryonic development stages are similar across species, DNA comparisons reveal genetic relationships, and geographic distribution shows patterns of migration and isolation. These evidences collectively support the theory of evolution.

What is the primary significance of the fossil record in studying evolution?

• It helps in predicting future evolutionary changes.

• It provides information about the climate of the past.

• It allows comparison of current organisms with those from the past.

• It shows the diet of ancient organisms.

What does the law of superposition state?

• Younger rock layers are found above older layers.

• Rock layers are always vertical.

• Older rock layers are found above younger layers.

• Rock layers are always horizontal.

Which of the following is an example of a homologous structure?

• The legs of a dog and the arms of a human.

• The wings of a butterfly and a bat.

• The tail of a monkey and the tailbone of a human.

• The fins of a whale and the wings of a bat.

What is a vestigial structure?

• A structure that has a new function.

• A structure that has lost its original function.

• A structure that is only found in fossils.

• A structure that is unique to humans.

Which of the following is a vestigial structure in humans?

• The appendix.

• The brain.

• The heart.

• The lungs.

What do Hox genes determine in an organism?

• The lifespan of the organism.

• The location of body parts during development.

• The size of the organism.

What is a phylogenetic tree used for?

• To show the diet of different species.

• To map the geographic distribution of species.

• To predict future evolutionary changes.

What did Darwin observe about the finches on the Galapagos Islands?

• They were all identical.

• They were not related to any other birds.

• They could not fly.

• They had different beak shapes suited to their environment.

Why are marsupials only found in Australia?

• They migrated from North America.

• They can only survive in Australian climate.

• They evolved from a common ancestor isolated in Australia.

• They were introduced by humans.
