In recent years, the young-earth creation (YEC) model for human origins has made great strides showing that human history is stamped all over our DNA, and in a manner consistent with the YEC timescale. One of the most fruitful arenas has been the history of the indigenous peoples of the Americas. Previous Y chromosome work has confirmed the known post-Contact history and discovered migration events in the pre-Columbian era. In this study, I replicate these Y chromosome findings in the field of human mitochondrial DNA (mtDNA). I also extend the history deep into the past and solve some of the lingering questions raised by the initial Y chromosome findings. Finally, I show new evidence for a mtDNA root, and for the validity of mtDNA as a molecular clock.
