Read the following statements regarding the anatomical and morphological evidences of evolution. Select the incorrect statement.

Options

  1. AThe eyes of an octopus and a mammal are analogous structures that evolved due to convergent evolution.
  2. BThorns of Bougainvillea and tendrils of Cucurbita represent homology.
  3. CThe wings of a butterfly and the wings of a bird are homologous organs indicating shared ancestry.
  4. DThe brains and hearts of vertebrates show structural similarities and are examples of divergent evolution.

Correct answer

C. The wings of a butterfly and the wings of a bird are homologous organs indicating shared ancestry.

Step-by-step solution

The wings of a butterfly and the wings of a bird are analogous organs, not homologous organs. They have different basic anatomical structures and embryonic origins but perform the same function of flight. This is an example of convergent evolution, which does not indicate shared ancestry. The eyes of an octopus and a mammal are analogous structures that evolved due to convergent evolution. Thorns of Bougainvillea and tendrils of Cucurbita represent homology as both are modified axillary buds. The brains and hearts
