Where do viruses, such as Ebola and HIV, come from and why they are so aggressive? This book changed tenets of evolutionary virology, developing the concepts of aggressive symbiosis and plague culling, which explain much of the horror of plague virus
The symbiotic pattern of evolution is everywhere and allows us a very different and fascinating window into the way symbiotic viruses work, since all viruses are symbiotic, including those involved in our human reproduction.
