Question

bats and birds are only very distantly related, and both evolved wings for flight in very different evolutionary pathways.
what is the term that describes the wing structures that these species evolved?

○ analogous structures
○ divergent structures
○ embryonic structures
○ homologous structures

Explanation:

• Analogous structures: Structures that have similar functions but different evolutionary origins. Bats (mammals) and birds (aves) evolved wings independently for flight (similar function), but their wing structures have different evolutionary paths.
• Divergent structures: Not a standard biological term in this context. Divergent evolution refers to species evolving different traits from a common ancestor.
• Embryonic structures: Relate to the development of embryos, not the functional - evolutionary relationship of adult structures.
• Homologous structures: Structures with similar evolutionary origins but may have different functions (e.g., human arm and bat wing - same bone structure from a common mammalian ancestor, but human arm for grasping, bat wing for flight).

Answer:

analogous structures
