It’s natural to think of viruses as enemies of mankind. More so when we are in the middle of a pandemic. But things aren’t quite that bad when we extrapolate the impact to all living beings throughout the history of life. I wrote this short article where I tried to explain one benefit of viruses which has had a huge impact on who we are. There is also a high level overview of how viruses operate. Please read if you are interested. If the topic fires your curiosity, Carl Zimmer’s ‘A Planet of Viruses’ is a good beginners level book and the book referenced in the article is a pretty detailed take on the science of viruses.
