The findings confirmed the timing of many migrations that are known from archaeological evidence, but there were a few unexpected implications in the data as well. For instance, the new family tree hints that humans first arrived in North America 56,000 years ago, much earlier than is currently estimated, and points to human migration to Papua New Guinea a full 100,000 years before the earliest documented evidence of habitation in that region. These tantalizing results do not necessarily mean that those migration timelines should be pushed back, but they do offer a compelling avenue of research going forward.To that end, the team hopes to continue adding branches to this unprecedented family tree. While this initial version of the project contains genetic information from several thousand individuals, the researchers said this method could potentially accommodate millions of genomes in future iterations, providing an ever-evolving portrait of our vast human family.“Although much work is still required to build the genealogy of everyone, the methods presented here provide a solution to this fundamental task,” the researchers concluded in the study.
