Excuse me, but they are indeed twins. They are not IDENTICAL twins, but they are, indeed, twins. It’s not my fault that Nick Contaflone failed basic biology.

Let’s look at the aforementioned Exhibit A:

NC: “it comes down to your definition of twins for non-humans, e.g., to me, puppy litter = siblings not twins.”

In other words: They were indeed born at the same time from the same mother, but HE does not call them “twins”.

NC: “Marble/Pinkie not identical twins, if they were I'd call them twins. But they're not, so how about "sametime sisters!”

He equates the term “twins” with “identical twins”, ignoring the possibility of fraternal twins in favor of the made-up “sametime sisters”.

He then goes on to stick his foot further down his throat with the next line:

NC: “But I'm not sure I'd call six baby mice fraternal twins, even though if a human had 6, they'd be twins obvi” [sic] “On the other hand if there were only two mice and they looked alike I'd call them twins. BIRTH IS SO CONFUSING”

A litter of six baby mice would not be twins either… they’d be sextuplets.

In biology, a litter of two is called “twins”, regardless of which mammal they came out of. These twins can be “identical” (their DNA is the same) or “fraternal” (their DNA is different). Fraternal twins may be of different sex, may look completely different, or may be nearly indistinguishable from each other (prompting them to be mislabeled “identical”).

A litter of three is called “triplets”. Four is “quadruplets”, five “quintuplets” and six “sextuplets”.

Technically, identical triplets are possible, as are a set of identical twins and a fraternal singleton, as well as three singleton fraternal triplets.

What can we deduce from “Exhibit A”?

1)	Pinky and Marble are born of the same womb, at nearly the same time. 2)	Pinky and Marble are NOT identical twins 3)	Nick Contaflone failed basic biology BIG TIME

We add to that the on-screen evidence, which is incontrovertible: Pinky states explicitly that Marble in her younger sister by a few minutes.

When a real-world horse carries two embryos to term, they are officially called “twins” (so Nick is wrong in that regard).

So we can say, beyond a reasonable doubt, that Pinky and Marble are, canonically, fraternal twins.

Unless someone wants to make an argument that they are the product of polygamous simultaneous pregnancies.
