Unfortunately, adaptation is not always a sign of intelligence. We often spread and use up our environment much like a virus or a bacterium. We have to use another gift of our biology and THINK. We can see the effects of our actions, but few are doing anything about it.
Exactly.
But I don't think we are complimenting our physiology. If modern medicine wasn't around, I believe we would be inferior to Palaeolithic humans in regards to survivability. And additionally, we (humans) are evolving (at least behaviourally) in a way that requires huge amounts of resources as a crutch for our survival.
