The Gene

Siddhartha Mukherjee · 2016 · 10 ideas · 10 min

Heredity is a code we've only recently learned to read and rewrite, and every triumph of genetics has been shadowed by the temptation to misuse that knowledge to sort and rank human beings.

Why this book

Siddhartha Mukherjee traces the gene from a vague Victorian intuition that traits pass between generations to the precise molecular unit scientists can now sequence, edit, and manipulate — weaving the history of genetics through Mendel's pea plants, Darwin's evolution, Watson and Crick's double helix, and the Human Genome Project, while never losing sight of a deeply personal thread: a family history of mental illness that runs through his own relatives. He argues genetics is the most powerful and most dangerous science of the last century, capable of curing disease and, in the wrong hands, of resurrecting eugenics in modern dress.

The book matters because gene-editing tools like CRISPR have moved genetic manipulation from theory to practice within a single generation, and Mukherjee insists we cannot responsibly wield that power without understanding the ugly history of people who thought they already understood heredity well enough to control it.

Who should read it

Anyone curious about where CRISPR, genetic testing, and hereditary disease research actually came from; readers of The Emperor of All Maladies will recognize the same blend of rigorous science and human stakes, this time centered on family and identity rather than cancer.
