A. Who thought this? Lamarck, Darwin, or both of them? Organisms have changed over time. Organisms changed because they wanted to survive. There was variation in a population. Certain traits helped organisms survive and reproduce better than other organisms without those traits. Organisms can never become extinct. The environment had something to do with why organisms changed. Parents are able to pass on at least some of their traits to their offspring. Parents are only able to pass on traits that they were born with. Organisms could decide to change something about their body and pass on that change to their offspring. Organisms are still changing. B. Evolutionary biologists studied both Lamarck and Darwin's theories very carefully. Darwin's theory has been supported by a lot of evidence. Lamarck's Theory of Inheritance of Acquired Characteristics has been disproved. Explain why we should believe Darwin and disprove Lamarck. Draw suitable examples to back your argument.

In the early 1800 s, French naturalist Jean Baptiste Lamarck suggested that the best explanation for the relationship of fossils to current organisms is that life evolves. He proposed that by using or not using its body parts, an individual may change its traits and then pass those changes on to its offspring. He suggested, for instance, that the ancestors of the giraffe had lengthened their necks by stretching higher and higher into the trees to reach leaves. Evaluate Lamarck's hypotheses from the perspective of present-day scientific knowledge.
