Evolution: The Theory of Evolution Questions and Answers Already Passed Who created the system for classifying and naming plants and animals? Malthus Lamarck Linnaeus Darwin Linnaeus Read the paragraph and then answer the question. A giraffe has to stretch its neck to reach leaves for food. Over time, the giraffe's neck gets longer from being stretched. The giraffe will then pass on this elongated neck to its children. Which scientist would have agreed with this explanation? Linnaeus Lamarck Malthus Darwin Lamarck Who had the idea to study humans as groups rather than as individuals? Malthus Darwin Lamarck Linnaeus Malthus What were Lamarck's ideas about evolution and why were those ideas incorrect? - Lamarck thought organisms changed during their lifetimes based on their needs. - He thought those changes were then passed on to the next generation. - Organisms cannot acquire traits during their lifetimes, like longer arms or a longer neck, and pass them on to their offspring. What did Darwin conclude about the finches on the Galapagos Islands that later supported his theory of evolution? Check all that apply. - The finches on the Galapagos Islands all had the same beak. - The finches on the Galapagos Islands had different beaks. - The beaks of the finches stayed the same over time. - The beaks of the finches changed over time. - The Galapagos finches had a common ancestor. - The Galapagos finches did not have a common ancestor. The finches on the Galapagos Islands had different beaks. The beaks of the finches changed over time. The Galapagos finches had a common ancestor. Why do fossils support the theory of evolution? Check all that apply. - Fossils show that organisms descend from a common ancestor. - Fossils show that traits change slowly over time. - Fossils show that organisms inherit acquired characteristics. - Fossils show that evolution always occurs very rapidly. - Fossils show extinct species. Fossils show that organisms descend from a common ancestor. Fossils show that traits change slowly over time. Fossils show extinct species. Several kinds of bears are found on Earth. Most bears are brown or black, but one type of bear, the polar bear, is white. What process led to this difference in fur color? Explain your answer. - The process that led to this difference in fur color is natural selection. - In an arctic environment, white bears blend in well with their surroundings, while brown and black bears stand out. - Brown and black bears would be easier to spot as prey, and would not survive in an arctic environment. - White bears are more adapted to the environment, so they would survive and reproduce. What are the four main components of Darwin's theory of evolution? - Organisms become different over time. - All organisms have common ancestors. - Evolution occurs slowly over an extended period of time.
