Previous studies of the human mitochondrial DNA mutation rate suggested the existence of a molecular "clock" that measured time consistent with the young-earth timescale, but these studies were limited to the D-loop (~7% of the mitochondrial DNA genome). Several recent studies measured the mutation rate in the entire mitochondrial DNA genome. I demonstrate that these new data agree with the expectations from D-loop results, further confirming the origin of the human race within the last 6000 years and strongly rejecting the evolutionary and old-earth creation timescales.
