After Anzick: Reconciling new genomic data and models with the archaeological evidence for peopling of the Americas

"...The origin of Native Americans has long been and is still one of
the most important topics in archaeology. The date, tempo, sources,
and pathways of the first migrations to the Americas are constantly
moving targets; archaeologists keep searching for earlier sites and
additional routes. As this volume was going to press, two new
claims received much publicity: cutmarked bones at Bluefish Caves
are suggestive of occupation of the Yukon at 24,000 cal BP
(Bourgeon et al., 2017), and the broken bones of a mastodont are
claimed to demonstrate hominin activity in southern California
130,000 years ago (Holen et al., 2017). Time will tell if these new
claims prove any more sustainable than those advanced for many
other now-forgotten or dismissed pre-Clovis candidates..."
