Question

darren needs to show the ancestral relationship between two species. what picture would best be suited to show a common ancestry? a diagrams of human, whale, bat limbs b diagrams of insects, bird, bat wings c partially visible diagram

Explanation:

Common ancestry is supported by homologous structures—similar bone arrangements from a shared ancestor, even with different functions. Option A shows human, whale, and bat forelimbs with identical bone patterns (humerus, radius/ulna, carpals, metacarpals, phalanges), proving shared ancestry. Option B has analogous structures (insect, bird, bat wings) with different origins, not indicating common ancestry.

Answer:

A. Diagram of human, whale, and bat forelimb skeletons
