Question

Houseflies have very tiny hind wings that are too small to lift them off the ground. Scientists have observed fossils of an ancient insect they believe is related to houseflies. However, these insects had second pair of wings that were much bigger. How does this show support for the theory of evolution? Houseflies have a vestigial structure. The ancient insects had a vestigial structure. Both share a homologous structure. Both share an analogous structure.

Answer 1

A. Houseflies have a vestigial structure.

Answer 2

Houseflies have a vestigial structure.

Step-by-step explanation:

Vestigial structures nonfunctional structures present in living organisms. These structures were functional in the ancestors of the organisms and have lost the ability to work during evolution.

Houseflies have tiny hind wings as vestigial structures that do not serve them in flying. However, these hind wings were much bigger and served in flying in ancestral species of houseflies as proved by the discovery of insect having bigger hind wings.
