[Continued from Part 1]
Shortly after sleuthing down the genetic trail left behind in the human genome and finding the genetic Eve, researchers became interested in doing the same for the genetic Adam. They had found the genetic “mother of all living;” now they wanted our original human father. What was needed was something as unique in male inheritance as the mitochondrial DNA what thought to be in female inheritance. The obvious equivalent was the Y chromosome, found only in male humans. This would form a trail to trace back to our first father. This was done, and the man was, of course, dubbed “Y Chromosome Adam.”
By analyzing DNA from people in all regions of the world, Well has concluded that all humans alive today are descended from a single man who lived in Africa around 60,000 – 90,000 years ago, a man also known as Y-chromosomal Adam. ~Wikipedia
Evolutionist Spencer Wells is the go-to guru evolutionist for the genetic Adam. His National Geographic documentary, which aired on PBS, presented the evidence from his research that was also found in his 2002 book, The Journey of Man: A Genetic Odyssey. The key here is that our genetic Adam was found to have a history only 3/4 as long as genetic Eve (90,000 years instead of 120,000 years). Although the 90,000 years does not fit the biblical timeline, the ratio of 3/4 does fit exactly.
MitoDNA is rarely distributed through the father, but almost always through the mother in each generation. The glitch that multiplied the speed of diversification in the mitoDNA was the discovery that males may rarely contribute to that diversity.
Think of the mitoDNA sample that was on the ark.
The three couples from which we are all descended had three women, all with three different genetic backgrounds. Combine that with the later rare contribution from the male mitoDNA, and you get a large mitoDNA diversity disembarking from the ark just over 4350 years ago.
Now consider the Y-DNA diversity on the Ark.
It is clear that only three Y-chromosomes led to all of the Y-DNA found in human males today if the biblical record is true. Were these three already diverse? No, all three were transmitted from the same man’s genome — Noah’s himself, as these were all his sons.
One portion of the human Y chromosome has been found to be identical among all living males. It is a 729-letter long sequence that should have randomly changed a great deal in 90,000 years. According to the biblically-based genetic history of humans then, 6000 years of female genetic diversity has been preserved from Eve through the flood and on to today. But by that same history, only 4450 years-worth of male genetic diversity would show up in the world today.
This works out cleanly as a 3/4 ratio to the female genetic diversity (and, therefore, genetic history). Once again, the genetic history of mankind correlates better with the biblical timeline than with the Darwinian one.
Early in the study of the human genome, there was evidence that the entire human race had been reduced to a tiny number about the time of the biblical reckoning of Noah’s Flood in Genesis. Before DNA sequencing was developed, blood serum protein analysis was used in doing genetic research. In the 1970s, it was realized that such a genetic bottleneck was indicated by the human hemoglobin protein found in the bloodstreams of all living humans. (“Population size and protein variation in man,” Genetical Research, vol 19, p73-89, 1972)
The research of scientists like Spencer Wells has verified many times over that all living humans are descended from one of four — and only four — human gene pools.
Think of this for a minute. Why not just one gene pool — whether you believe in evolution or not? Think of the crew on Noah’s ark. There was Noah and his family — that makes one gene pool. Then there were the three wives of the three sons, presumably from three additional gene pools — making a total of four. Once again, modern genetics has corroborated the biblical account of the history of humankind — not the Darwinian version.
But can three couples begin a population that reaches 8 billion within only 4350 years? Yes.
Mathematician John Heffner has calculated that given only an average family size of 2.5 children per generation, from the flood until now, the world population would be estimated at 6.5 billion. If the first Homo sapiens came on the scene even 500,000 years ago, then that number could be potentially many trillions of times greater.
Why is the human population not vastly greater than it is now, as the Darwinian model would predict? Why is the population right at the prediction of the biblical model? Logic dictates, once again, that the biblical account of the history of the human race is indeed the true and actual account. There simply is no reason to doubt the accuracy of the biblical history of mankind. There is a plethora of scientific reasons from the field of genetic research to merit the wholesale abandonment of the distorted Darwinian history along with its erroneously inflated timelines.
