Acknowledgments

We wish to express great thanks to our daughter, Melissa Gerald, whose advice and suggestions as a biological anthropologist were of utmost assistance in preparing all aspects of this book. Our son, Marc Gerald, was instrumental in introducing us to Sterling Publishing and providing encouragement and invaluable professional support throughout this project. Christina Gerald is thanked for her loving support during the writing of this book, and we also wish to acknowledge Jon Ivans for his suggestions for book-entry inclusions. The excellent support of the editorial and production staff of Sterling Publishing—in particular, Melanie Madden, our editor—and Scott Calamar at LightSpeed Publishing helped bring this book to fruition, and all are also most greatly appreciated.
