Evidence for Evolution Quiz

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

• Evolution is powered by supernatural processes.

• Living things do not change over time.

• All living things on Earth are related and evolved from a common ancestor.

• All living things have a fixed genetic code.

What distinguishes whales from fish?

• Whales lay eggs.

• Whales have placentas and give live birth.

• Whales are cold-blooded.

• Whales have gills.

What evidence suggests that whales evolved from four-legged land mammals?

• Whales have scales similar to fish.

• Whales have fins instead of limbs.

• Whales have tiny bones resembling hip and leg bones.

• Whales can breathe underwater without coming to the surface.

What does embryology reveal about the development of whales?

• Whale embryos develop feathers at some stage.

• Whale embryos are identical to fish embryos.

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

• Whale embryos develop gills at early stages.

What is the significance of the basilosaurid whales' nasal opening position?

• It has no significance in the study of evolution.

• It is an intermediate trait showing evolution from land to water.

• It shows they were fully adapted to land living.

• It indicates they could breathe underwater.

What does the presence of small legs in basilosaurid fossils suggest?

• They indicate a mutation with no function.

• They were remnants from their evolutionary past.

• They were used for walking on land.

• They were used for swimming.

How does DNA evidence support the theory of evolution?

• It shows no relation between different species.

• It disproves the theory of evolution.

• It reveals close genetic matches between species, indicating common ancestry.

• It proves that all living things have identical DNA.

What common ancestor do whales and hippos share according to genetic findings?

• A large aquatic reptile.

• An ancient bird species.

• A land-dwelling mammal that lived roughly 54 million years ago.

• A small amphibian-like creature.

Which of the following is a shared feature of whales and hippos?

• Both species have multi-chambered stomachs.

• Both species lay eggs.

• Both species have external testicles.

• Both species are primarily carnivorous.

What does the evolutionary history of whales demonstrate?

• Whales have not evolved over time.

• Whales have always been fully aquatic.

• Whales and fish share a direct ancestor.

• Whales evolved from four-legged land mammals.
