Review for'Survival of the Sickest: The Surprising Connections Between Disease and Longevity (P.S.)'

"Survival of the Sickest: The Surprising Connections Between Disease and Longevity" by Dr. Sharon Moalem is a compelling and thought-provoking exploration of how certain diseases have played an unexpected role in human evolution and survival. In this book, Moalem delves into the paradoxical idea that some of the very ailments that plague humanity today were actually advantageous to our ancestors in their respective environments. Through a blend of genetics, evolutionary biology, and medical history, Moalem presents a narrative that challenges the conventional understanding of disease and health.

One of the most striking aspects of "Survival of the Sickest" is Moalem's ability to present complex scientific concepts in an accessible and engaging manner. He uses a storytelling approach that captivates the reader, weaving together historical anecdotes, personal stories, and scientific research. This makes the book not only informative but also highly readable, even for those without a background in science or medicine. The inclusion of real-world examples helps to illustrate the book’s key points, making the science come alive in a way that is both relatable and intriguing.

Moalem explores a range of diseases and conditions, such as diabetes, hemochromatosis, and sickle cell anemia, and explains how these conditions may have conferred survival benefits in certain environmental contexts. For instance, he discusses how the genetic mutation that causes hemochromatosis, a condition characterized by excessive iron accumulation in the body, may have helped our ancestors survive the plague by depriving bacteria of the iron they need to thrive. Similarly, he examines how the gene responsible for sickle cell anemia provides a protective advantage against malaria, a deadly disease that has historically ravaged many parts of the world.

The book also delves into the concept of "thrifty genes," which are thought to have helped our ancestors survive periods of famine by promoting fat storage. Moalem suggests that these same genes may now contribute to the prevalence of obesity and diabetes in modern societies where food is abundant. This exploration of genetic trade-offs highlights the complex interplay between our evolutionary past and present-day health challenges.

One of the strengths of "Survival of the Sickest" is its ability to provoke critical thinking about the nature of disease and health. Moalem encourages readers to consider the broader evolutionary context of human biology and to question the simplistic notion that diseases are merely detrimental. By highlighting the adaptive advantages that certain conditions may have provided in the past, the book offers a nuanced perspective on the relationship between genetics, environment, and health.

However, some readers may find that Moalem's arguments occasionally rely on speculative connections that are not fully substantiated by empirical evidence. While the book is thoroughly researched and cites numerous scientific studies, the nature of evolutionary biology means that some hypotheses remain difficult to prove definitively. Despite this, the book's overarching thesis is compelling and invites further exploration and discussion.

In conclusion, "Survival of the Sickest" is a fascinating and enlightening read that challenges conventional wisdom about disease and longevity. Dr. Sharon Moalem's ability to present complex scientific ideas in an accessible and engaging manner makes this book a valuable addition to the popular science genre. It prompts readers to reconsider the role of disease in human evolution and to appreciate the intricate connections between our genetic heritage and contemporary health. For anyone interested in the intersections of genetics, evolution, and medicine, "Survival of the Sickest" is a must-read.
