Yes, but all that proves is that some subset of humanity is capable of doing it. Not humanity as a whole.
> Yep, the myth of the good savage.
Actually a lot of the verbal culture of many tribes show that they understand how they are dependent on the animals for their food source, and you can find active efforts not to overhunt in many cultures. It seems to me the main thing that has increased isn't necessarily intelligence, but greed.
What's the point of this argument? Yes, humanity as a whole has become very specialised. With the consensus of the community and enough will power a subset of humanity can achieve almost anything we can conceive. Is this any different than toting dolphin pods that pass on their hunting tricks? Or captive gorillas that can communicate? Potential is not limited to the lowest common denominator.
