If scientific evidence mattered to YE creationists they wouldn’t be YE creationists.
These folks like to be wrong....it's more fruitful than being absolutely right.
I think it is a policy here at FR that we quote verbatim the Titles.
That said, how do you get from exponential decay of fossilized bone DNA to ‘Young Eartherism taking a hit’?
Nothing in the Bible says the Earth is young and for all we know Adam and Eve lived as Spiritual Beings in the Garden of Eden for billions of years overseeing all lifeforms before they were tempted and chose to follow evil (Satan, the spiritual demon of death).
Are you going to use BCE in your reply?
Figure 1 (page 4729) of the linked article shows the '242 bp mtDNA sequence' survival rate going to zero at 4000 years, and Table 1 (also page 4729) shows temperature effects on half-life: A 6X drop in half life if the 'storage' temperature is increased from 15C to 25C...
The unknowns involved (e.g., storage at higher assumed temperatures for a good portion of time; exposure to moisture; effects of pressure; etc) don't lend themselves to profound conclusions.... Other than the one stated in the Tagline.
It seems to me, if true that DNA has a roughly 500 year half life, then the discovery of Dino DNA would absolutely disprove that dinos have been extinct for millions of years. The absence of such discovery doesn’t conclusively tell you anything.
ping for reference. BTW, I have seen DNA decay as an argument FOR YEC. Some Japanese fellow claiming thermal decay predicts no DNA could survive more than about 10K years, even under the most perfectly protected conditions. Creation magazine (Answers in Genesis) touted this as a basis for being suspicious of dating any discovered dinosaur DNA to periods significantly beyond the 10K limit. And this new proposal on half-life does not seem to be inconsistent with that premise. Perhaps I am missing the point, but I do not see how this harms the essentials of the YEC position at all.
You see? May as well ask the YEC’s how much evidence it would take to make them a heretic an atheist or think that God is dead, impotent or aloof. No amount of scientific evidence will convince them that the Earth and Universe are old or that God would use non miraculous means to create.
