species are closely related and may have evolved from a common ancestor. [Monkeys driving a pink car]
It does not, however, prove that we are all somehow related to the Kardashians.
We'll get over that crushing disappointment somehow.
All right, if you chose “A,” then you don’t know a bat’s wing from your left [A man raises his left arm and a bats wing appears underneath]
arm, both of which happen to be examples of homologous structures.
They're similar in anatomy, but not necessarily in function.
While the anatomical similarity part might sound promising, answer A has nothing to do [Hand shaking a bottle of prenatal tablets]
with anything prenatal.
So “A” is incorrect.
Vestigial organs are useless body parts.
Like the top skin fold on your ear, or your wisdom teeth. [A man with an x-ray of his mouth and an arrow pointing to a wisdom tooth]
Considering your teeth aren't going to help you figure this question out, we can safely
eliminate answer C. How about B?
Well biogeography is a study, but it researches the geographic distribution of plants and animals
Biogeographers have this intense need to know why birds are rarely seen at the mall. [A bird walking through a store]
It's mostly because they're so...cheep...
And that's it for B?
It's so wrong.
That brings us to comparative embryology, which is the study of structural similarities [A cracked egg with an embryo inside]
before an animal is born.
Ringing any bells?
Aristotle is recognized as the first person to compare embryos of different species in [Aristotle looking under a microscope]
an effort to prove that all animals are somehow structurally related.
The Greek philosopher was also the first to know the correct answer to our question is [Aristotle stood with the letter D]
“D,” comparative embryology.
If you chose “D”, you're practically the next Aristotle.
Or, as we like to think of it, Aristotle 2: Electric Boogaloo. [Aristotle with a guy and girl performing dance moves]
