Human DNA Variation Linked to Biblical Event Timeline by Jeffrey Tomkins, Ph.D. | Jul. 23, 2012
Each person is different, and each, except an identical twin, has unique DNA differences. These differences can be traced across global populations and ethnic groups. Furthermore, recent research provides interesting insight about the approximate time that these DNA differences entered the human race.
A new study reported in the journal Science has advanced our knowledge of rare DNA variation associated with gene regions in the human genome.1 By applying a demographics-based model to the data, researchers discovered that the human genome began to rapidly diversify about 5,000 years ago. Remarkably, this data coincides closely with biblical models of rapid diversification of humans after the global flood.
The vast majority of DNA base sequences between any two humans are nearly identical, so the few differences are traceable among people groups. The human genome project has continued to analyze thousands of humans throughout the world for variation in their DNA sequence. Researchers link this variation with many human traits and heritable diseases.2
Typically, this variation is evaluated using single DNA base differences or single nucleotide polymorphisms (SNPs) between individuals and populations. Because of the type of standardized "gene chip" technology commonly used, most SNP analyses evaluate only the most variable parts of the human genome and, therefore, exclude the much less variable protein-coding regions.
The recent Science study analyzed the DNA sequences of 15,585 protein-coding gene regions in the human genome for 1,351 European Americans and 1,088 African Americans.
The data proved ideal for examining the course of human genetic variation over time, partly because protein-coding regions are less tolerant of sequence variation than other parts of the genome; these regions record more reliable, or less "noisy" historical genetic information.
Typically, evolutionary scientists incorporate hypothetical deep time scales taken from paleontology or just borrowed from other authors to develop and calibrate models of genetic change over time.3 In contrast this Science study used demographic models of human populations over known historical time and known geographical space. The resulting data showed a very recent, massive burst of human genetic diversification.
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?
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.
The Bible clearly indicates that modern humans descended from Noah's three sons— Shem, Ham, and Japheth—and their wives. Such a dramatic reduction (bottleneck) in the overall size of the human population would certainly have been followed by a burst of genetic diversity, as it does in many animal populations.4 The genetic data from this research paper spectacularly confirms key biblical events and their Bible-based timelines.

“The recent Science study analyzed the DNA sequences of 15,585 protein-coding gene regions in the human genome for 1,351 European Americans and 1,088 African Americans.”
The first scientific error in the study is the “human genome variation” in the data - the human’s sampled - 1)was too small, and 2)too small a representation of the diversity of global human population, leaving out the Middle East (home of the Bible), the Indian “Sub-Continent”, all parts of Asia, all of the Pacific Island peoples and all of South America.
Reference needed please. The only thing by a Jeffrey Tomkins in Science Magazine is as part of a listing of authors in an article on gene transfer in bacteria (not the same Tomkins as far as I can tell). Nothing in the American Journal of Science either. However, a Life Science quiz does eventually link back to two articles in "Science" that studied the cortex of the brain. Neither one mentioned any worldwide floods but were hailed by the ICR because they did not discuss evolution. There are also links to an article by Brian Thomas, MS which also start down the path to the great flood. I also found a listing that references the journal "Science" but this links back to the ICR and I cannot find any actual links to this journal.
In other words, I cannot find the original work in "Science" magazine.
Step 1: Look at article I posted. Find first reference:
Tennessen, J. et al. 2012. Evolution and Functional Impact of Rare Coding Variation from Deep Sequencing of Human Exomes. Science. 337 (6090): 64-69
Step 2: “Copy” the reference into your browser.
Step 3: Open Google Scholar
Step 4: Paste the reference into Google Scholar.

Another article to which Science refers comes to a similar conclusion because:
The development of agriculture and livestock in the transition from the Paleolithic to the Neolithic era some 10,000 years ago heralded a demographic explosion in our species that is still ongoing today. Paradoxically, this rapid population growth, made possible by improved living conditions, may be responsible for an excess of damaging variants in our genome
In other words, as humans developed agriculture and animal husbandry they became more diverse.
Sorry, but your first post said "The original work appeared in "Science" magazine". The author, Jeffery Tomkins, does not appear in Science, the article that he used to draw his conclusions does. The other article that I referenced above speaks of the transition from Paleolithic to Neolithic over 10,000 years ago. Does this mean that the young Earth theory is wrong or can we just skip this background foundation because it goes back too far?
Sorry, but cherry picking articles to find evidence that you want while ignoring others that do not fit your conclusions is dishonest.
