Certain flightless beetles have wings that have no function. The wings are an example of which type of structure?

(2) Answers

The wings on the beetles are examples of vestigiality. Vestigiality is a structure with attributes that have apparently loss its ancestral function but stil present during evolution. It is a normal evolutionary process in the changing environment that does not pressure them to evolve.


These wings are a type of vestigial structures, that is they are a remainder of the time when the beetles could actually fly, but stopped doing so over time due to the lack of stimulus for flight.
