Some of those papers appeared in august journals such as Nature, Science, and Philosophical Transactions of the Royal Society of London. My own favorite saw print in a more specialized organ called Parasitology. This one, titled “Coevolution of Hosts and Parasites,” appeared in 1982. It began by dismissing those “unsupported statements” in medical and ecological textbooks “to the effect that ‘successful’ parasite species evolve to be harmless to their hosts.”
