Award-winning, celebrated New York Times columnist and science writer Carl Zimmer presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities...

But, Zimmer writes, “Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are—our appearance, our height, our penchants—in inconceivably subtle ways.” Heredity isn’t just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors—using a word that once referred to kingdoms and estates—but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer’s lucid exposition and storytelling, this resounding tour de force delivers it. 

Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world’s best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.An Amazon Best Book of June 2018: Heredity is a lot more complex than most people think. In She Has Her Mother’s Laugh, New York Times columnist Carl Zimmer dives deep into the ways that we pass along our genetic inheritance. Through history, science, and a boatload of personal curiosity (the book originated from questions he had regarding his own child, and he had his entire genome mapped in the process of writing it), Zimmer seeks to retell the story of heredity in broader and more inclusive terms than the ones we’re used to hearing. For example, who we become is determined by our ancestors’ genes, yes; but it is also a product of our own cells—for one cell can contribute to millions of future cells. How we treat ourselves, what we learn, and even how we feel, eventually contributes to our hereditary future. The forces at work are myriad, mostly unseen, and subject to variables that we barely understand. Zimmer is trying to help us here, to teach us, and in doing so he succeeds in entertaining us as well. --Chris Schluep, Amazon Book Review
