Human ears have muscles responsible for ear movement, but they are nonfunctional in most humans, unlike in other primates. this is an example of which form of evolutionary evidence?
a. homologous structures
b. analogous structures
c. vestigial structures

C. The vestigial structures. A vestigial structure is an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species. Often, these vestigial structures were organs that performed some important function in the organism at one point in the past. However, as the population changed due tonatural selection, those structures became less and less necessary until they were rendered pretty much useless. While most of these types of structures would probably disappear over many generations, some seem to keep being passed down to offspring even though they have no known function.
