Concept:Lamarck’s theory explains evolution through environmental pressure, use and disuse of organs, and inheritance of acquired traits, but not natural selection.
Explanation:Lamarck proposed that changes in the environment force organisms to develop specialised characters.
Features that are used become stronger, while unused parts weaken and disappear.
He believed these acquired characters are inheritable and can be passed to offspring.
He did not include natural selection of offspring in his theory.
Natural selection belongs to Darwin’s theory of evolution.
Answer:The correct option is A: There is natural selection of offspring.
