How very cool is this!
About 3.5 million of today's Ashkenazi Jews -- about 40 percent of the total Ashkenazi population -- are descended from just four women, a genetic study indicates.
And how do we know this? From the interpretation of mtDNA:
The study involved mitochondrial DNA, called mtDNA, which is passed only through the mother. A woman can pass her mtDNA to grandchildren only by having daughters. So mtDNA is "the perfect tool to trace maternal lineages," Behar said in a telephone interview.
If God withholds His judgement for another century or so (at least) and if we would just use science for the good, we'd be astonished at how much brilliant data is floating just beneath our fingertips. In fact, the more science reveals, the more that it ends up backing up Revelation in the long run.
Take this tidbit as an example. Judaism is a matriarchal religion. If only the father is Jewish, the child is not technically Jewish. While many want to dismiss this prescription, we see here that God said it for a reason. The genetic imprint is from the mother.
Each woman left a genetic signature that shows up in her descendants today, he and colleagues say in a report published online by the American Journal of Human Genetics. Together, the four signatures appear in about 40 percent of Ashkenazi Jews, while being virtually absent in non-Jews and found only rarely in Jews of non-Ashkenazi origin.
Imagine who those four women they were. They had absolutely no idea that they would be responsible for millions of progeny (remember that there are 3.3 million alive today, but how many have existed in these family lines over the milennia?). One can scarce take it in. Of course, simple exponential math would make it clear.
"Be fruitful and multiply" was an edict that had results beyond comprehension.
