After a long isolation in Beringia, populations move into the Americas as the ice sheets separate. A Pacific coastal route opening around 16,000 years ago is now favoured over the interior ice-free corridor, which appears to have been biologically barren until later. Genomic evidence indicates a rapid southward expansion and an early split into northern and southern branches. Within a few thousand years people are present from Alaska to Patagonia.
