Sharon Moalem, MD, PhD, is an award-winning physician-scientist and geneticist. He is the author of the New York Times bestseller Survival of the Sickest and Inheritance, an Amazon Best Science Book of the Year, among other books. His work brings together evolution, genetics, and medicine to revolutionize how we understand and treat disease, and his clinical research led to the discovery of two new rare genetic conditions, and to his discovery of a first-in-class antibiotic which targets ‘superbug’ infections. His books have been translated into more than 35 languages.
This was a very thought–provoking book on the nature of evolution. I really liked how this book gave me new perspective on why some people could be more susceptible to certain diseases than others. I'd always wondered how "dangerous" genes, like those that cause diabetes or something, were passed on if they could kill you, but as the book puts it: "Why would you take a pill that was guaranteed to kill you in forty years? Because it will save you tomorrow." The book theorizes that the genes that cause diabetes was helpful to those living in cold climates, because it'd help you conserve energy and stay warm by changing your sugar levels. This book is a bit old, so I'm curious as to whether or not the theories in this book ended up being proven correct—it did tend to draw on a lot of speculation at times. Overall, this book probably deserves five stars, and I'd say this book is a must read if you are interested in biology or genetics.
I think that the scientific theories and stories presented in this book are still relevant, even though they are dated. There is also the use of some gendered language and examples that don't necessarily work well in 2025. I would love to see updates on this work! (I read an older version, so perhaps there are ...)
A book recommended and borrowed from my sister Kayla. It was a difficult read at times since I am not as verse in science but I ended up learning a lot about evolution and genetics! The chapters go on many tangents to explain all the historical context, biological functions, and what we can learn from it and then finally circles back to the main point.
Not too into the weeds of the science, but still cool to learn about what we consider diseases now were actually genetic mutations that occurred to help people survive and adapt to the environment in the past.
