10 Magical Game Of Thrones Details Explained With Science
7. Dragons
Dragons. Of course we had to talk about dragons.
Although, if we were unbearable pedants, we would correctly refer to them as wyverns, for that is actually what Daenerys' "dragons" are. Luckily, we aren't unbearable pedants, so we won't.
Although dragons, much to the dismay of Magic: The Gathering enthusiasts the world over, do not exist, there's no solid biological limitation or evolutionary reason why they shouldn't.
Anyone who has ever lit their fart (so every teenage boy for a start) will confirm that animals are more than capable of producing flammable gasses and expelling them at pace. Animals are also capable of producing electrical sparks, such as the many types of electrical fish. If, by some quirk of evolution, these two properties came together in a reptile then, boom, you'd have a dragon.
One drawback of your real-world dragon, however, is that it probably wouldn't be able to fly unless they were either (A) much smaller or (B) filled with gas like a huge dragon-shaped lilo. Coincidentally, delicious flammable methane is not only highly flammable, but lighter than air, so the whole concept of dragons isn't as outlandish as it seems.
