> they tend to create more problems than they solve. The natural solution to natural problems is to evolve Is dying of drought, while being survived by less thirsty mutants, really solving any problems? I guess there's some genetic lineage that keeps on replicating. Then we humans decide whether it's similar enough to keep labelling it the same "species". If so, maybe we declare that the species solved the problem of the drought. Meanwhile, I doubt there were any creatures happy to die of thirst for lack of an aqueduct. If we ignore that unfortunate reality and measure success by DNA replication, then civilization might still being doing alright. We've had a bit of a population explosion in the last few hundred years.
