The article referred to this a geographically constrained set of samples. So the 500 years pertains to those samples. On the other hand since temperature is an influence, I’ll bet that the DNA of some of those frozen mammoth carcasses is probably still in pretty good shape.
The point of this article is, half the DNA vanishes every 521 years; half the remainder in another 521 years; etc.
Thank you for the reply. I read where they gave the specific conditions on which they based their conclusions.
I am still puzzled why the headline characterized it as a hit to YEC theory. If anything, it is potentially devastating to the “millions and millions of years” narrative of evolutionary theory.
Is there something I’m missing or is truthfinder9 taking a logical mulligan?
