Over the last decade, Africa has taken a central position in the search for the timing and mechanisms leading to modern human origins, and the rich archaeological and human paleontological record of North Africa is critical to this search.  In this volume, we bring together new research into the archaeology, human paleontology, chronology, and environmental context of modern human origins in North Africa.  The result is a volume that better integrates the North African record into the modern human origins debate and at the same time highlights the research questions that are currently the focus of continued work in the area.​
