8 | Carl Zimmer on Heredity, DNA, and Editing Genes

Our understanding of heredity and genetics is improving at blinding speed. It was only in the year 2000 that scientists obtained the first rough map of the human genome: 3 billion base pairs of DNA with about 20,000 functional genes. Today, you can send a bit of your DNA to companies such as 23andMe and get a report on your personal genome (ancestry, health risks) for about $200. Technologies like CRISPR are allowing scientists to edit genes, not just map them. Science writer Carl Zimmer has been following these advances for years, and has recently written a comprehensive book about heredity: She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity. We talk about how our understanding of heredity has changed over the years, how there is much more to inheritance than simply listing all the information we pass down in our DNA, and what the future might hold in a world where genetic manipulation becomes widespread.
