Which statement is incorrect?
Correct answer: D. Analogous organs are functionally different but structurally alike.
- A. Homologous organs are functionally different but structurally alike.
- B. Examples of homologous structures are arms of man, forelimbs of cat and flippers of whale.
- C. Examples of analogous structures are wings of bats, birds and insects.
- D. Analogous organs are functionally different but structurally alike.
Explanation
Analogous organs are those which have different structures, but their function is the same in different organisms. Wings of bats, birds, and insects are structurally different, but their function is the same, i.e., flying.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
