Question

certain flightless beetles have wings. their wings are an example of which type of structure? embryonic structure vestigial structure homologous structure adapted structure

Explanation:

• An embryonic structure is related to the early - stage development of an organism.
• A homologous structure is one that has a similar origin but may have different functions (e.g., human arm and bat wing).
• An adapted structure is one that has changed to suit a particular function or environment.
• A vestigial structure is a remnant of a structure that had a function in an ancestor but has lost most or all of its original function in the organism. Flightless beetles' wings are remnants (they don't use them for flight anymore), so they are vestigial.

Answer:

vestigial structure
