Question

structures are fully functional, show evidence of a common ancestor, and may or may not have the same function in different species.

Answer 1

Anatomical there are similarities among many organisms. Homologous structures found in different species that are anatomically similar because they have been inherited from a common ancestor.

Answer 2

Answer:

Flippers of whale and forelimbs of human have a common basic structural plan but perform functions of steering during swimming and holding the things respectively.

Explanation:

Homologous structures have a common basic structure but perform different functions in different species. For example, flippers of whale and forelimbs of human have a common skeletal structure with the humerus, radius, ulna, carpels, etc. but perform different functions. Flippers in the whale are adapted to serve in swimming while forelimbs of human do the function of grasping and holding objects.
