So in an effort to encourage people to read more sciencey things I've stumbled upon today's article. Needless to say, I'm changing "Who would win" to ask you, my readers,
"Who's more badass?"
(Credit to the Dresden Codak Comics... because they're awesome)
For those of you who don't actually want to read the whole thing and make fun of me in the comments section it goes like this.
"When a wasp approached a swarm of ants on the tuna bait, the ants would begin charging at it, spitting acid and trying to bite the insect, which is 200 times larger. Often this was enough to make the poor wasp flee in a panic, but in rare bursts of bravery, it would occasionally grab a Napoleonic ant in its mandibles, fly backward a few centimeters with the insect twitching in its jaws, open its mandibles, and let gravity do its work."
Keep in mind here that in this test, the wasp was ~200x LARGER than the ants.
Cooperlogic behind the cut. Debate in the comments.
