  • What is the main reason why blue whales are not considered fish?
    They eat different types of food than fish.
    Their body structure is more similar to mammals than to f
    They do not live entirely underwater.
    They are too large to be fish.
  • How do scientists visualize what extinct ancestors looked like?
    By studying ancient paintings.
    By using skeletal and fossil evidence.
    By guessing based on modern animals.
    By combining DNA from living species.
  • What is inferred about the common ancestor of mammals, including humans and whales?
    It lived about 4 billion years ago.
    It had structures similar to modern mammals.
    It was a large aquatic animal.
    It had a skeleton identical to humans.
  • What does the presence of shared body structures between species suggest?
    A shared evolutionary history.
    They evolved at the same time.
    They have similar diets.
    They have no differences.
  • What is the significance of all living things sharing basic traits like cell structure and DNA?
    It explains why mammals are the most complex organisms.
    It proves that all life on Earth is unrelated.
    It shows that all life evolved from a common ancestor.
    It demonstrates how whales are more advanced than fish.
  • What do the small leg bones in blue whales indicate?
    They serve no evolutionary purpose.
    Whales once had ancestors that walked on land.
    Whales are still evolving into land animals.
    They are used for swimming.
  • How do whales and humans demonstrate their mammalian connection?
    By having lungs, producing milk, and similar bone structures
    By walking on land regularly.
    By living in the ocean.
    By laying eggs and having shiny scales.
  • According to the article, what was the appearance of the earliest mammalian ancestor?
    A single-celled organism.
    A small, mouse-like creature.
    A fish with gills and fins.
    A large blue whale-like animal.
  • What evidence do paleontologists use to trace evolutionary connections between species?
    Comparing the color of their skin.
    Observing the habits of modern animals.
    Studying their diets.
    Fossilized remains and DNA analysis.
  • Which of the following is a characteristic shared by humans and blue whales?
    Both have lungs for breathing air.
    Both have scales on their bodies.
    Both lay eggs.
    Both breathe through gills.
