I would argue that ants are one of the most dangerous, effective and successful creatures on earth. But as we know they are not the dominant form of life. They also vary through-out their many species; some have potent venom while others even have acid. Many species are ferocious beasts alone but their true strength lies in numbers. The only true thing even able to wipe out a whole colony is Cordyceps.
Despite this they are not the dominant life form on earth, at least in the we are, but like robo-cop; We can rebuild them, bigger and better. What can I do to Legionary Ants (more commonly called Army Ants) to make them as dominant and successful as humanity?
