The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.

Vestigial organs have long been one of the classic arguments used as evidence
for evolution. The argument goes like this: living organisms, including man,
contain organs that were once functional in our evolutionary past, but that
are now useless or have reduced function. This is considered by many to be compelling
evidence for evolution. More importantly, vestigial organs are considered by
some evolutionists to be evidence against creation because they reason a perfect
Creator would not make useless organs.
I just know this much about vestigial organs, maybe I helped you:))
