Europe’s first farmers

Archaeological digs in caves and elsewhere have turned up evidence of their Mesolithic technology: flint-tipped tools with which they fished, hunted deer and aurochs (a now extinct species of ox), and gathered wild plants.

So the only sensible answer to the question, how do we stop this from happening again, is: by doing all we can to prevent such pathogens infecting humans in the first place.
