How do homologous structures show
common ancestry?
A. They show us the genetic makeup of extinct organisms.
B. They show the situation that caused a species to branch
off from the original.
C. They show similarities between species and which
organism first developed the structure.
D. They are the structures that exist in the oldest living
member of an existing species.

According to the context, homologous structures show similarities between species and which organism first developed the structure.

What are homologous structures?

They are structures that in different species fulfill similar functions, but have different embryonic origins, by virtue of their similarity, they suggest their connection with a common ancestor.

That is to say, it is the expression of the same genetic combination and that it is supposed to come from a common ancestor.

Therefore, we can conclude that according to the context, homologous structures show similarities between species and which organism first developed the structure.
