The Clock That Should Not Exist

DNA is not a stable molecule. From the moment cellular repair ceases at death, it breaks down through four measurable chemical pathways, dominated by hydrolytic depurination, whose temperature dependence follows the Arrhenius law with high precision. This means that for any specimen of known burial temperature, the surviving fragment length is a clock that can be read directly, independent of the geological dating framework. I apply the most rigorous directly observed decay rate available, the moa bone kinetics of Allentoft et al. (2012), to the famous Sima de los Huesos hominin femur from Atapuerca, Spain, a specimen conventionally assigned an age of approximately 430,000 years yet recovered from a cool, wet, non-frozen cave averaging 10.6°C. Researchers themselves describe this specimen as the only non-permafrost site on Earth preserving Middle Pleistocene DNA, an explicit admission that it violates every other observed survival limit. Reading the clock forward, I predict that the observed fragmentation state, fragments capped near 45 bp with a mode near 30 bp, corresponds to a true postmortem interval on the order of thousands of years, not hundreds of thousands. My central reading combines the two conditions the cave actually has, its seasonal temperature cycle and its poorer-than-average preservation, into a single effective rate of 6.194 × 10−6 per nucleotide per year. That rate places the burial at a midpoint near 4,485 years, with a 30 bp reading of about 5,350 years and a 45 bp youngest-bound of about 3,570 years, squarely within the post-Flood window. The simpler single-factor scenarios bound this between roughly 5,261 and 8,342 years; every one is thousands of years, not hundreds of thousands. I show that survival to 430,000 years at this fragment length would require a sustained burial temperature near negative 9.8°C, which the cave has never provided. Under the assumptions of the observed decay model, the measured fragment lengths are inconsistent with the published geological age and rather align with the biblical timeline.

His research focuses on the evolutionary theory of aging, which accounts for senescence through mutation accumulation, antagonistic pleiotropy, and disposable soma theory. This work engages origins science, with particular attention to molecular aging, mutation rates and accumulation, biological evolution, genetic variation, and historical linguistics.
