Question

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 represented in this pair of species? (Ostrich) ( Humming Bird) A) Homologous B) Developmental C) Vestigial D) Inherited

Answer 1

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.
