Book review – Plagues upon the Earth: Disease and the Course of Human History

7-minute read

It might sound crass to write that the COVID-19 pandemic is just the latest in a long line of infectious disease outbreaks, but a little perspective helps. Historian Kyle Harper previously impressed me with his study on the role of climate and disease in the decline of the Roman Empire. In Plagues Upon the Earth, he offers a global, multidisciplinary environmental history of infectious disease, showing that it is a force that has both shaped and been shaped by human history. This magnificent book stood out as much for its nuance and academic rigour as it did for its readability.

Book review – Discovering Retroviruses: Beacons in the Biosphere

In the already unusual world of viruses, retroviruses stand out for being even more so. Called “retro” because they reverse the flow of genetic information from RNA to DNA, rather than the normal DNA to RNA, they have turned out to be ancient, omnipresent, and incredibly influential. They are also important as they cause diseases such as AIDS. With Discovering Retroviruses, Anna Marie Skalka delivers a book dedicated to this particular group that is as technical as it is fascinating.

Book review – Virusphere: From Common Colds to Ebola Epidemics: Why We Need the Viruses that Plague Us

Beware the virus. If there is one message physician and evolutionary biologist Frank Ryan is hammering home with this book, it is this. Viruses are absolutely everywhere and more numerous even than microbes. So much so that Ryan speaks of the virosphere rather than the biosphere. But more than harbingers of disease, they are also agents of evolutionary invention. Now why does that sound familiar?

Book review – Viruses: Agents of Evolutionary Invention

When I reviewed Planet of Microbes: The Perils and Potential of Earth’s Essential Life Forms, I remarked that microbes are everywhere. If you are willing to stretch the definition of life a bit further still, there is one entity that is even more numerous and omnipresent: the humble virus. We tend to think of viruses almost exclusively in the context of disease (see for example The Invisible Enemy: A Natural History of Viruses). But, as virologist and pharmaceutical researcher Michael Cordingley shows here, they are so much more than mere pathogens and have a huge influence on evolutionary processes in all organisms. This book paints a remarkable portrait of these unusual life forms.
