In some way, it sort of forces us to rethink the definition of "intelligence"..it's almost like in computer science..what I think they call "distributed processing"..each ants' miniscule brain linked together..the collective whole is somehow far more powerful.
BTW..do you happen to know where in Africa that was, and what species of ant? Other species, like the army ants..have evolved a totally different, yet equally successful, model..the army ants swarm through the jungle, eating everything they encounter..they stay in one spot for a few days..the form a "living nest"...they all link thir limbs together...and then, when the surrounding food source is all eaten..they swarm to another location..almost the exact opposite of the ants in the video..
no idea where it was...in another 500 years the ants may have street names posted....*LOL*...(not being nasty)..it just hit me. Finding stuff at dump.com after receiving it in an email is troublesome.
