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

A.J. Jacobs has received some strange emails over the years, but this note was perhaps the strangest: You dont know me, but Im your eighth cousin. And we have over 80,000 relatives of yours in our database.

And so begins A.J. Jacobss 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.

This book is about A.J. Jacobss family. But its also about your family. Because it is the same family.
