The discovery of 21,000-23,000-year-old human footprints at White Sands National Park in New Mexico is one of the most exciting developments in the study of the deep past in recent years. But do these footprints hold up to real scrutiny? And if they’re real, how do they change our understanding of the first people in the Americas? I asked two experts on the earliest inhabitants of the Americas what they thought of this incredible new evidence: Dr. Jessi Halligan, Assistant Professor of Anthropology at Florida State University, and Dr. Shane Miller, Associate Professor of Anthropology at Mississippi State University. Both have extensive experience on the topic, and help us understand precisely what these footprints tell us about the human past in North and South America.Patrick's book is now available!
