b
This is an example of homologous structures, which indicates that they share a common evolutionary origin.
This is the best argument because homologous structures suggest that bird and butterfly wings evolved from a common ancestor and have similar functions but differing structures due to adaptations to different environments or ecological niches.
Which statement provides the best argument for why bird and butterfly wings evolved to have a similar function but differ in structure?
a
This is an example of vestigial structures, which indicates that the common ancestor of birds and butterflies had the same structure as birds.
b
This is an example of homologous structures, which indicates that they share a common evolutionary origin.
c
This is an example of embryological structures, which indicates that bird and butterfly wings have similar function because they develop in much the same way.
d
This is an example of analogous structures, which indicates that they are not closely related even though they perform the same function.
