Which of the following statements best summarizes Lamarck's views on evolution?

Lamarck's views on evolution are primarily centered around the idea of the theory of acquired characteristics. He proposed that organisms can adapt to their environments during their lifetime and that these adaptations can be passed on to their offspring. For example, he suggested that if a giraffe stretches its neck to reach higher leaves, its offspring would inherit a longer neck as a result of this effort. This belief underscored the possibility of change in an organism's traits based on its experiences and uses, which differentiates his theory from Darwin's natural selection. Lamarck's ideas laid important groundwork for the study of evolution, even if they have since been widely revised and challenged by modern genetics and evolutionary theory.
