The idea that humans were involved in any way in eradicating dozens of species of giant animal when we were still hunter-gatherers has important implications in any case. It was thought, until relatively recently, that it was only when humans invented agriculture several thousand years ago that our species’ relationship with the natural world become unbalanced. Until then, humans had a close affinity with nature. But if ancient hunter-gatherers played a part in wiping out these species of huge animals as long as 50,000 years ago, humanity’s supposed innate harmony with the living world appears misplaced.
As the piece points out, that the megafauna all disappeared as humans turned up is at least an indication that it wasn’t just happenstance.
And the idea that hunter gatherers are innately in harmony with nature is simply too stupid for words in the first place. They’re predators on it.
