Concept:Lamarck’s theory of evolution is based on environmental influence, use and disuse of organs, and inheritance of acquired characters.
Explanation:Lamarck believed that changes in the environment bring about changes in species.
He also held that organs used frequently become well developed, while unused organs become vestigial.
He further proposed that acquired characters are inherited by offspring.
Option D states that survivors in a competitive community must have inherited useful traits.
This describes natural selection, which is a Darwinian idea and not a Lamarckian postulate.
Therefore, option D is the statement that is not part of Lamarck’s theory.
Answer:D. survivors in a competitive community must have inherited useful traits
