Humans as Kudzu

A fascinating take on human propagation across the planet:

"You'd think that the fact that we're adapted to Africa in a way we aren't adapted to anywhere else would be an advantage, but it turns out not to work that way. The overwhelming factor, for H. sapiens as well as stink bugs, is that our native range is adapted to us -- humans or bugs become dangerously invasive when we can escape not just the limited space of our native range, but the constraints on our population that come from other co-native species: predators or parasites (including diseases)."
