Question

birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because
multiple choice
bird wings, but not insect wings, function on the physics principles of lift.
insect wings are vestigial.
there is no fossil link between these groups.
the wings are not homologous structures with a common ancestral origin.
they did not evolve in the same region or live at the same time

Explanation:

Homologous structures indicate relatedness as they have a common - ancestral origin. Since bird and insect wings do not have a common ancestral origin, they are not homologous and thus this similarity is not evidence of relatedness.

Answer:

D. the wings are not homologous structures with a common ancestral origin.
