Detailed explanation-1: -The horns of ruminants have resulted from the ruminants’ butting their heads together during combats. These examples, which appear naive in light of later discoveries, constitute some of the evidence on which Lamarck rested his theory.
Detailed explanation-2: -Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this process led to change in a species. A male fiddler crab uses its front claw to ward off predators and to attract mates.
Detailed explanation-3: -Lamarck believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves.
