Lamarck's vision of evolution differed from Darwin's in that Lamarck believed a. living things evolve in an upward direction. b. behavioral changes modify heritable traits. c. genetic differences among individuals in the population allow for evolution. d. a and b only. e. none of the above.
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.
