In the 1950s, 100 million rabbits were overrunning Australia – an invasive species crisis that led people to unleash germ warfare – infecting them with a deadly virus called myxomatosis. It was devastating – 99.9% of the rabbits across the continent died, according to Penn State University biologist Andrew Read.  But the survivors rebounded, and over the subsequent decades the virus became less virulent, and then deadlier, and the rabbits evolved resistance. I talk to Dr. Read about that episode, what scientists learned from it, and how those lessons might apply to understanding the evolution of SARS-CoV-2.
