Answer 1

Answer:

Lamarckism: Lamarck gave the principle of 'use or disuse of organs’. He proposed that the reason behind evolution was the changes in the morphological activities of the organism. For example: giraffe has a long neck because it used to browse on leaves of tall plants by extending their neck for several generations, shoulders of iron smith are strong due to repetitive hammering movements, wings of ostrich and emu are weak because they are not used for flying, legs of birds and swan are used for swimming because they live in water. These characters are termed as acquired characters which are transferred from one generation to another.
