Genetic Evidence of Noah's Flood

The Y - Chromosome & mtDNA (basics)

The sex chromosomes are named X and Y. Males have two distinct sex chromosomes (X & Y) and females have two of the same (X & X). So the Y chromosome is passed on only from father to son.

Mitochondria – these are little compartments inside each of our cells which house the components to produce the cell's energy. They have their own, separate strand of DNA (separate from the main/nuclear/chromosomal DNA) and it's called Mitochondrial DNA (mtDNA). Since only the mitochondria contained in the fertilized egg are used at conception, mtDNA is only inherited from the mother. Males are therefore dead-ends for mtDNA.

When DNA (which contains the sex chromosomes) and mtDNA are passed down to offspring, mutations (copying errors) can and do occur. DNA receives over a 100 mutations per generation whilst mtDNA receives a lot less (due to the size of mtDNA being a lot smaller than DNA – approx 16,000 base pairs compared to approx 3 billion base pairs for DNA).

Because of these mutations, DNA and mtDNA have been slowly diverging/degrading from the DNA and mtDNA of our first ever ancestors (whose possible identities are about to be discussed).

Reminder:

Y:                Father -> son
mtDNA:      Mother -> all children

What we should expect for proof of Noah's Flood?

To begin with, the first Book of the Bible (Genesis) was written nearly 3,500 years ago (around 1,400 BC) by Moses. There is very good evidence to support this.

Genesis states that eight people were on the Ark: Noah and his wife, their three sons and their three wives. So:

1. There should be signs of a population bottleneck in which humanity almost became extinct.

2. How many different Y chromosomes were on the Ark? One – the three sons inherited their Y chromosome from Noah, and since it's only one generation down, mutations would have been little to none.

So, there should be only one Y chromosome lineage today.

3. How many different mtDNAs on the Ark for offspring? Three. The three wives of Noah's sons. (The Bible doesn't mention that Noah and his wife had any more children).

So, there should be three mtDNA lineages today.

4. These three mtDNA lineages should trace back to a single female ancestor (Biblical Eve). Proof of this would be that the three mtDNAs lineages are similar due to small amounts of time from Eve to Noah (1,500 years).

5. Due to the relatively high amount of mutations humans pass down to children (approx 100 mutations per generation), and the Flood occurring about 4,500 years ago, genetic diversity in humans today should be consistent with thousands, not millions, of years. (Human history, not the age of the earth – the age of the earth is irrelevant).

What we observe today in genetics

1. The Human Genome Project was declared complete in April 2003. One of its findings was that all humans share 99.9% DNA. They suggested that this is due to a population bottleneck in our past where our numbers dwindled so low that we teetered on the brink of extinction. https://www.genome.gov/about-genomics/fact-sheets/Genetics-vs-Genomics

2. Y chromosomes are indeed similar worldwide. No divergent Y lineages have been found. Therefore, evolutionists acknowledge a paternal common ancestor, calling him Y-chromosomal Adam. https://en.wikipedia.org/wiki/Y-chromosomal_Adam

3. There are indeed three main mtDNA lineages found worldwide today. Evolutionists have labeled these lines “M”, “N”, and “L”. (In a court of law, this would be considered inculpatory evidence.) https://en.wikipedia.org/wiki/Haplogroup#mtDNA

4.There is little difference between these three mtDNA lineages when looking at them, which is consistent with there being only 1,500 years from Adam/Eve to Noah. It also tells us they must have originated in a single female, who lived not long before the bottleneck. (Mitochondrial Eve).

5. Since humans have virtually identical DNA, the genetic diversity is consistent with thousands of years, not millions of years.


Thaler & Stoeckle study

https://phys.org/news/2018-05-gene-survey-reveals-facets-evolution.html

This study was done in 2018 and is the largest study of its kind. These are evolutionist mind you but what they found was that there was an event that wiped out nearly all of not only humans, but all life within the past 200,000 years. They claim that humans and animals originated at about the same time and that there is an abscen of "in between" species.

Their hypothesis is that the similair mitochondrial uniformity across animals is best explained the same way we explain human similiarity, meaning we came out of a bottleneck or originated at the same time (Ark). This is especially powerful when you realize that their 200,000 year date is simply an assumption and that if we go by the empirical mutation rates we get this "All humans and animals arose at roughly the same time 6,000 years ago".

This study was a complete bombshell and tells us a literal Biblical model of our history, very shocking. You can even see where the very people conducring the study say they "fought against the data".

New analysis points to a recent human genome

The following paper came out not that long ago (Jan 2013), throwing the idea that humans have been around for hundreds of thousands of years (millions of years if you include earlier “ancestors”) into question:

10th Jan 2013 - “Analysis of 6,515 exomes reveals the recent origin of most human protein-coding variants”

http://www.nature.com/nature/journal/v493/n7431/full/nature11690.html

A couple of excerpts (SNV = Single Nucleotide Variant = 1 mutation/copying error):

“Large-scale surveys of human genetic variation have reported signatures of recent explosive population growth, notable for an excess of rare genetic variants, suggesting that many mutations arose recently”
“We estimate that approximately 73% of all protein-coding SNVs and approximately 86% of SNVs predicted to be deleterious arose in the past 5,000–10,000 years”

What this is basically saying is, most mutations in humans occurred in the last 5,000-10,000 years. Obviously, this was not expected by evolutionists who believe that humans have been around for 200,000 to millions of years.

If evolution is to be believed, then for hundreds of thousands of years (or a few million years), human DNA hardly received any mutations, then in the last few thousand years most of the DNA damage we've all inherited occurred. Sound feasible? Or how about this: there was simply no human history prior to a few thousand years ago.


Discussion

You may be wondering why you haven't heard about this overwhelmingly supportive proof of Noah's Flood before. You would be right to wonder if it's “too good to be true”. To answer this, you need to know that one of the basic guiding principles of science is naturalism. This means that supernatural causes must be ruled out as scientific explanations. All proposed scientific explanations must be testable and repeatable, and obey physical laws. Scientists simply cannot explain an event by invoking divine intervention.

In short, even if the evidence points to supernatural causes (e.g. Biblical events), they won't be able to make that conclusion. They will find the best “natural” explanation and run with that, no matter how improbable it is or how many unanswered questions it requires to work. Some might say if scientists are only allowed "natural" explanations, then they are not pursuing the truth; they are pursuing a natural explanation - even if a natural explanation is impossible.
