Theory of Inheritance of Acquired Characteristics
Jean-Baptiste de Lamarck based his theory on the observation that individuals inherit the traits of
their ancestors. He proposed that "all the acquisitions or losses wrought by nature on individuals, through the
influence of the environment in which their race has long been placed, and hence through the influence of the
predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new
individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the
individuals which produce the young".
Example, giraffes stretching their necks to reach leaves high in trees strengthen and gradually
lengthen their necks. These giraffes have offspring with slightly longer necks. In essence, a change in the
environment brings about change in “needs", resulting in change in behavior, bringing change in organ usage
and development, bringing change in form over time -and thus the gradual transmutation of the species.
