Otzi the iceman carbon dating
A deep cut on his right hand suggests he may have been involved in hand-to-hand combat with a knife-wielding foe.Material was extracted from Ötzi’s pelvic bone using a trephine needle, the same instrument used for bone marrow biopsies.Of course, they did not question the carbon dating process.Instead, the narrator said, “The discovery of the ax meant they were stepping out of the age of stone tools a thousand years before experts thought possible.” This prompted Patrick Hunt, an alpine archaeologist, to state the following: To be that far ahead so far back, this is simply incredible.Apparently murdered, his body was then frozen for millennia—5,300 years according to the program.Can modern forensic science provide answers explaining Ötzi’s death? Was he a fugitive on the run, killed in battle, or murdered by an acquaintance?Much like a modern-day crime scene forensic investigation, the scientists attempted to put together the clues to figure out how Ötzi died, why he was killed, and who killed him.
From this material, the researchers isolated some DNA, and they also found evidence of arthritis, atherosclerosis, and Lyme disease.
The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.
Animals and people eat plants and take in carbon-14 as well.
PBS recently aired an intriguing documentary (first aired in 2011) covering an investigation into the death of earth’s oldest cold case.
Ötzi, named for the Ötztal Mountains in which he was discovered just 100 yards from the border of Austria and Italy in September 1991, is believed to be the oldest intact human body ever found.
