But overall, they're going to be ravished, they're going to be destroyed. It's going to be a bigger impact than the Black Plague had on Europe, this new introduction of these diseases into the new world. Not only did the old world bring all their old cooties to the new world and kill everybody, but they also found some pretty cool materials to fight diseases back in Europe. This probably should go in the plant section, but they found quinine, a malaria-fighting plant, and that's going to be a drug that is really going to wipe out malaria, for the most part, in the old world because of the new world. So old world wins, new world loses. So in terms of animals, the old world just has a lot more animals. There were 72 classifications of large mammals in the old world, and of those 72, something like 13 had been domesticated.
