Question

Quizplus · Accepted Answer

Homologous structures refer to anatomical features that have a common evolutionary origin and share similar underlying structures, despite their superficial differences. This suggests that they have a similar function and may have been adapted for different purposes over time. Homoplasic structures, on the other hand, are superficially similar anatomical features that have evolved independently and have different underlying structures. Symplasic structures and dependent structures are not commonly used biological terms.
