There are 3 million species of animals living in tropical rain forest, and one of them, the red fire ant, lives underground, under constant threat of annihilation from flash floods. Nature doesn’t care, if a species wants to survive, it has to prove it deserves to.
When the floods come, fire ants hold on to each other, creating a living raft that could float until the water recedes, months if necessary. So how does the species figure something like that out? Instinct? Trial and error? Was there one fire ant that was being swept away by the rushing water, and grabbed on to another ant, only to find that together, they could float?
