Researchers discovered intact red blood cells in the body of Ötzi the Iceman, a world-famous once-frozen natural mummy found in the Alps in 1991. Livescience called them the "world's oldest blood cells."1 But clear evidence shows that other blood cells hold the real record.
Forensic researchers have gleaned a wealth of information about the Tyrolean Iceman, commonly known as Ötzi. For example, chemical traces show places he had recently been, tiny particles revealed his last meal of red deer and bread, and his boots were likely made by an ancient professional bootmaker. An arrowhead had lodged in his left shoulder, damaging an artery and likely causing his death. Just this year, geneticists sequenced his DNA, finding that modern inhabitants of the Mediterranean's Corsica have the most similar sequences.2
Now, scientists discovered intact red blood cells in tissue samples from a wound that his hand suffered, as well as the arrow wound to the chest. Their research appeared in the Journal of the Royal Society Interface, where the authors wrote "It was initially assumed that the blood had disintegrated owing to autolysis within the corpse."2 Autolysis is the process where oxygen, which is especially abundant within oxygen-carrying red blood cells, reacts with and fragments the proteins that comprise cells. Few, if any, expected that red blood cells could have persisted within Ötzi for perhaps thousands of years until today.
What appeared to be red blood cells were probed with two techniques to ensure their identity. Atomic force microscopy and Raman spectroscopy both clearly confirmed Ötzi's red blood cells, according to the report.3 But in contrast to the news headlines, they do not appear to be the oldest.
In 1992, researchers assigned Ötzi to a European Copper age that occurred after Stone age remains were deposited in that area.4 He probably lived only a few thousand years ago after the post-Flood ice age.5
But red blood cells from even earlier specimens have appeared under paleontologists' microscopes. Totally unexpected, the bone marrow of a T. rex recovered in 1990 from Montana had what appeared to be red blood cells. Their story was recounted in Earth magazine.
The lab filled with murmurs of amazement, for I had focused on something inside the vessels that none of us had ever noticed before: tiny round objects, translucent red with a dark center. Then a colleague took one look at them and shouted, 'You've got red blood cells. You've got red blood cells!'6
Their technical report appeared in Science in 2005.7 Some of the same authors involved in a much larger team described what looked identical to red blood cells found in a hadrosaur bone as "cell-like structures" in Science in 2009.8
Of course, both the T. rex and hadrosaur are widely believed to be tens of millions of years old. Any red blood cells should have long since disintegrated. The Ötzi study even verified that his blood cells had lost much of their integrity by comparing the Raman scans with those of modern blood samples. But not only did the dinosaur bone marrow results show clear pictures of red-colored, round disks inside blood vessels, they also detected hemoglobin.7 Why are these not the rightful record-holders for oldest blood cells?
Since the dinosaur fossils formed as a result of Noah's Flood, which produced the Alps mountain range that Ötzi later walked upon, the dinosaur red blood cells are older than Ötzi's by perhaps a millennium or two. In order to maintain belief in millions of years, those who insist that Ötzi's are the oldest blood cells must ignore the dinosaur data.
