Evidence From Genetics Confirms the Bible

There are literally oceans and mountains of evidence confirming the truth and historicity of the Bible. But surely genetics is not part of the evidence...is it?

With a straightforward reading of the flood account in Genesis, what kinds of things would we expect to see today?

  • Billions of dead things buried rapidly
  • Sedimentary layers all over the earth covering vast distances
  • Fossilized sea creatures buried high above current sea level
  • Sorted and distinct layers of soil with little erosion between them
And this is exactly what we find when you begin digging down into the soil. But genetics? Come on?!?!? This has been a bastion of evolutionary ideas since Francis and Crick discovered the DNA molecule? Right?

Well before we make up our minds, let's talk history for just a second to get some background. Genesis 7 tells us that Noah, his wife, their three sons and their three daughter's in law were the only eight humans saved from the flood by the ark.

We'll also need a tiny lesson in genetics. Mothers pass along to their daughters a genetic unit called mitochondrial DNA (mtDNA). The mtDNA is not passed along from fathers, so it remains unchanged (other than mutations) from mother to daughter. Therefore, we can trace back a lineage through the mtDNA. How many mtDNA lineages were on the ark? Three. The wives of Noah's sons all have recorded children. It is possible that there could have been four, but the Bible does not record Noah's wife bearing any more children after the flood.

So, if that story is true, how many mtDNA lineages might we expect to find today? Three, right? Well, that is exactly what secular genetics confirms. The current mtDNA lines have been given the designations "M", "N", and "R". God's Word is confirmed yet again.

If you're interested in seeing a more detailed explanation of this article, you can see it on creation.com's website.

Excellent. But then my questioning mind asks, why are there three, and not just one?

That's a great follow-up question. The lines do back back to a single woman, which is why they have been able to track the differences from each other to distinguish the three lines.

A quote from the creation.com article reads,

"Let’s assume ten female generations from Eve to the ladies on the Ark. M and N are separated by about 8 mutations (a small fraction of the 16,500 letters in the mitochondrial genome). R is only 1 mutation away from N. This is an indication of the mutational load that occurred before the Flood. Given the assumption that mutations occur at equal rates in all lines, about four mutations separate M and N each from Eve (maybe four mutations in each line in ten generations). But what about R? It is very similar to N. Were N and R sisters, or perhaps more closely related to each other than they were to M? We’ll never know, but it sure is fascinating to think about."
