It's All Relative Adventures Up and Down the World's Family Tree

A.J. Jacobs has received some strange emails over the years, but this note was perhaps the strangest: “You don’t know me, but I’m your eighth cousin. And we have over 80,000 relatives of yours in our database.”<br> <br>And so begins A.J. Jacobs’s quest to build the biggest family tree in history. In an era of us-versus-them thinking, this book is a hilarious, heartfelt and profound exploration of what binds us all – where family begins, how far it goes, and the science that is revolutionizing the way we think about ethnicity, history and the human species.<br> <br>This book is about A.J. Jacobs’s family. But it’s also about your family. Because it is the same family.
