Verified step by step guidance

Understand the concept of homologous structures: Homologous structures are anatomical features in different species that have a similar origin but may serve different functions. They arise from a common ancestor.

Identify the common ancestor: Determine if the anatomical features in question could have originated from a common ancestor, which is a key characteristic of homologous structures.

Analyze the evolutionary development: Consider the evolutionary pathways of the species involved. Homologous structures often develop through divergent evolution, where related species evolve different traits.

Compare the anatomical features: Examine the structural similarities between the features. Homologous structures often have similar bone structures or arrangements, even if their functions differ.

Apply the concept to the given options: Evaluate each pair of anatomical features to determine if they share a common evolutionary origin, focusing on structural similarities rather than functional ones.
