Murder! Espionage! Cosmic Rays! The History of Carbon-14 Is Way More Thrilling Than You Think
Radiocarbon-dated to bce , the body is that of a man aged 25 to 35 who had been about 1. The small rocky hollow in which he lay down to die was soon covered and protected by glacial ice that happened to be melting 5, years later when his body was discovered by modern humans. It was at first believed that the Iceman was free of diseases, but in researchers discovered that his body had been infested with whipworm and that he had suffered from arthritis; neither of these conditions contributed to his death. He also at one time had broken his nose and several ribs. His few remaining scalp hairs provide the earliest archaeological evidence of haircutting, and short blue lines on his skin lower spine, left leg, and right ankle have been variously interpreted as the earliest known tattoos or as scars remaining from a Neolithic therapeutic procedure. The various clothes and accoutrements found with him are truly remarkable, since they formed the gear of a Neolithic traveler. A woven grass cape and a furry cap provided additional protection from the cold, and he wore shoes made of leather and stuffed with grass.
How Old is Earth, and How Do We Know?
The hand axe found with the body of the Alpine Iceman is one of the rare copper objects that is firmly dated to the early Copper Age because of the radiocarbon dating of the axe wooden shaft. Here we report the measurement of the lead isotope ratios of the copper blade. The results unambiguously indicate that the source of the metal is the ore-rich area of Southern Tuscany, despite ample evidence that Alpine copper ore sources were known and exploited at the time.
The experimental results are discussed within the framework of all the available coeval archaeometallurgical data in Central-Southern Europe: they show that the Alps were a neat cultural barrier separating distinct metal circuits. The direct evidence of raw metal or object movement between Central Italy and the Alps is surprising and provides a new perspective on long-distance relocation of goods and relationships between the early Copper Age cultures in the area.
The result is in line with the recent investigations re-evaluating the timing and extent of copper production in Central Italy in the 4 th millennium BC.

What’s more, the discovery proves that the Stone Age homicide victim had a quick, if not painless, death.

No blood residue had previously been detected, however, despite various studies detailing his violent death due to an arrow shot and other injuries. Each minute movement of the probe was recorded with a laser, “so you get a three-dimensional image of the sample in a very tiny scale,” Zink explained. The scans revealed classic “doughnut shape” red blood cells, the team reported Wednesday in the journal Interface.
While past studies have suggested evidence for prehistoric blood on Stone Age tools and other artifacts, “you can never really be sure, because you can see structures which are quite similar to red blood cells” such as pollen grains or bacteria, Zink commented. To confirm they were indeed dealing with human blood cells, the researchers illuminated the wounds with a laser.
Dating techniques used by archaeologists
As a science, archaeology focuses on understanding the many ways people of the past lived. This requires archaeologists to not only be trained in social science, but also use techniques from other fields like the life and physical sciences, earth and environmental sciences, mathematics, and the humanities. Archaeologists use these techniques from other fields, as well as those developed within the field, to more thoroughly interpret and understand the information we record when conducting archaeological investigations.

Five days after Ötzi’s discovery, an archaeologist was with the aid of radiocarbon dating, the Iceman” used for his clothes and tools in an interactive way. So that Ötzi does not decay and scientific investigations can carry on, he must be preserved Dating methods in archaeology: two examples of dating methods.
The nature of his life and the circumstances of his death are the subject of much investigation and speculation. He is Europe’s oldest known natural human mummy and has offered an unprecedented view of Chalcolithic Copper Age Europeans. The tourists, Helmut and Erika Simon, were walking off the path between the mountain passes Hauslabjoch and Tisenjoch. They believed that the body was of a recently deceased mountaineer.
The next day, eight groups visited the site, among whom were mountaineers Hans Kammerlander and Reinhold Messner. The body was semi-officially extracted on 22 September and officially salvaged the following day. It was transported to the office of the medical examiner in Innsbruck , together with other objects found. On 24 September, the find was examined there by archaeologist Konrad Spindler of the University of Innsbruck. He dated the find to be “about four thousand years old”, based on the typology of an axe among the retrieved objects.
Near Tisenjoch the glacier which has since retreated complicated establishing the watershed and the border was drawn too far north.
Ötzi the Iceman: scientists find 5,000-year-old blood sample
Photograph: Thilo Parg. Over the past 10 years, a new field has emerged which is revolutionising our understanding of human history and anthropology. Ancient DNA, the analysis of DNA from human remains, is beginning to unravel some of the mysteries of the past, like the migration of people and the spread of culture, through periods of time from hundreds to tens of thousands of years.
Until recently, our reconstruction of the past relied on archaeology and tentative hypotheses, but now the hard science of genetics is beginning to take a leading role in understanding the population patterns we see across the globe today. That was a big moment.
Using a wealth of new scientific information, a seasoned homicide small, but they also show little sign of hard use, suggesting that Ötzi was no manual laborer. relies heavily on forensic science, but in Ötzi’s case, the techniques have scientists were able to place the date of Ötzi’s death at sometime in.

OTZI, THE ICEMAN
Previously, tattoo scholars were divided: Many believed that a mummy from the Chinchorro culture of South America had the oldest tattoo—a pencil-thin mustache. Recovered from El Morro, Chile, the mummy was believed to be about 35—40 years old at the time of his death around B. But after reviewing the facts, we were compelled to publish the article as soon as possible to set the record straight and stem the tide of future work compounding the error.
The art of tattooing is ancient, but when it began is unknown. Written records date the art of tattooing back to fifth-century B. Beyond that, evidence of tattooing is found in art, from tattoo tools and on preserved human skin; the latter is the best evidence and only direct archaeological proof.
