The Global Mega-Colony of Ants

Ants are fascinating. They’re small and individually dumb, but together they can form very complex societies capable of activities like farming and altering entire ecosystems. In this video, Kurzgesagt shows how the Argentine ant became one of the most numerous and successful species of ant in the world, forming a single mega-colony across the entire Earth, from Argentina to the US to Japan.

“The enormous extent of this population is paralleled only by human society,” the researchers write in the journal Insect Sociaux, in which they report their findings.

However, the irony is that it is us who likely created the ant mega-colony by initially transporting the insects around the world, and by continually introducing ants from the three continents to each other, ensuring the mega-colony continues to mingle.

“Humans created this great non-aggressive ant population,” the researchers write.
