[ExI] The Ant Game

[Stuart LaForge]

Ants are such awesomely successful creatures. They rival us for  
dominance of the world. Scientists estimate that 20% of all  
land-animal biomass is contained in ants. Army ants are particularly  
noted as being one of the top predators in the South and Central  
American tropics where they devour anything that cannot get out of  
their way. Here is a cool video of army ant attacking a nest of their  
larger but nowhere near as sophisticated cousins the wasps. Notice the  
wild bridge they built out of their own bodies.

They build such bridges to cross obstacles like rivers that are many  
meters across. The game is try to guess *why* these army ants built  
that particular bridge.
