Question

select the correct answer from each drop-down menu.

the images show the wings of two different organisms. the wings of the housefly and the bat are analogous structures. this indicates that
choose an answer

• their wings evolved from a common ancestor
• their wings have different evolutionary lineages
• the two species do not share any common ancestors at all

housefly
bat

Explanation:

Identify the relationship between the structures

Using the Analogous Structures knowledge point
The wings of a housefly (an insect) and a bat (a mammal) serve the same function (flight) but do not share a common embryonic or evolutionary origin. Therefore, they are classified as analogous structures.

Determine the evolutionary implication

Using the Convergent Evolution knowledge point
Because analogous structures arise when different species adapt to similar environmental pressures rather than inheriting the trait from a shared ancestor, this indicates that their wings have different evolutionary lineages.

Answer:

The images show the wings of two different organisms. The wings of the housefly and the bat are <blank>analogous structures</blank>. This indicates that <blank>their wings have different evolutionary lineages</blank>.
