But the historical record makes Homo sapiens look like an ecological serial killer.
No doubt humans were an invasive species when they arrived on other continents. That said, I think that without an awareness of the ecological consequences of their migration, we shouldn’t judge them, or deem human action during this time as outside of the natural order. Like all species, humans were motivated by their own survival. That is the basis of macroevolution. Ecosystems are constantly evolving, as well.
