• The natural tendency of internal parts to decrease in size

• A continuous 'new need' or want created by the environment

Answer 1

The second postulate of Lamarckism states that a new organ develops in response to a continuous 'new need' or want created by the environment. The environment creates needs, and the organism responds by forming new organs.
