4) Study the wings of the birds in the two images below. Which of the following words applies to only one of the wing structures
Pani-rosa [81]

Answer:

The answer is A) Homologous structures

Explanation:

Homologous Structures:

  • Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
  • Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
  • For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
  • Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
  • Inherited and developmental are out of context in terms of evolutionary relationships.
