In a study reported in the July 6, 2012 issue of Science, researchers analyzed the DNA sequences in a large group of European Americans and African Americans. Their data, coupled with demographic models, revealed the recent burst in genetic diversification. Dr. Tomkins comments:
The authors wrote, "The maximum likelihood time for accelerated growth was 5,115 years ago." Old-earth proponents now have a new challenge: to explain why—after millions of years of hardly any genetic variation among modern humans—human genomic diversity exploded only within the last five thousand years?Once again, science is the ally of the truth found in Holy Scripture.
However, the same data conforms to and dramatically confirms biblical history. Since the author's date represents the maximum time, the actual DNA diversification event probably occurred even sooner. A biblical time scale indicates that a global flood occurred about 4,500 years ago, and this closely correlates with the time scale of the researcher's estimate.
