Scientists led by Eiriki Sunamura of the University of Tokyo, have discovered that a single mega-colony of ants has colonised much of the world.
(The species, Argentine ants, are living in vast numbers across Europe, the US and Japan and they belong to the same interrelated colony. They will even refuse to fight one another. In Europe, one vast colony is thought to stretch for 6,000km (3,700 miles), while another in the US, known as the 'Californian large', extends over 900km (560 miles) along the coast of California. The colony could rival humans in the scale of world domination. After all, we never seem to refuse to fight one another.)
