Measured decay rates of some proteins are compatible with an age of about 4,500 years (since the Flood), but not with many millions of years.However, seeing not only proteins but even cell microstructures after 4,500 years is surprising, considering how easily bacteria can normally attack them.

Bone would hinder the cells from swelling that comes before cells self-destruct (autolysis) as well.

They also propose that the surfaces of the mineral crystals attract and destroy enzymes that would otherwise speed up degradation.

These lesions are caused by a combination of normal chemical activity within the cell and exposure to radiation and toxins coming from environmental sources including cigarette smoke, grilled foods and industrial wastes.

But even there, there is no way that DNA could last the evolutionary time since dino extinction.

And indeed, antibodies specific to PHEX detected this unique bone protein.

They try to solve this problem by proposing that bone protects the cells from bacteria that cause degradation.

Their figures of the time till complete disintegration of DNA (“no intact bonds”) is 22,000 years at 25°C, 131,000 years at 15°C, 882,000 years at 5°C; and even if it could somehow be kept continually below freezing point at –5°C, it could survive only 6.83 Ma—only about a tenth of the assumed evolutionary age.

The researchers state: However, even under the best preservation conditions at –5°C, our model predicts that no intact bonds (average length = 1 bp [base pair]) will remain in the DNA ‘strand’ after 6.8 Myr.

Other evolutionists saw the baneful implications to their long-age dogma, and claimed that the blood vessels were really bacterial biofilms, and the blood cells were iron-rich spheres called framboids.
