उत्तर
According to Lamarckism, long-necked giraffes evolved because of stretching of necks over many generations by short-necked ones.
Explanation:
Lamarck suggested that giraffes stretched their necks to reach food and that this acquired change was passed to their offspring. Natural selection, rather than stretching, is the explanation linked to Darwin.
