I’m reading a book right now (Plagues and Peoples by William H. McNeill) that at one point compares the spread of early humans out of Africa to a disease. He has a good argument, saying that the ability of humans to use technology allowed them to mutate, in effect, faster than local wildlife could respond and comparing human expansion to a pandemic. I might have used an invasive species as a metaphor rather than a disease because in this case it wouldn’t really be a metaphor – humans were at the time an invasive species. But in a book about pathogenesis in humans, such a comparison is apt.
So here is the question: to what extent is our history as a species inevitable?
