Who Killed the Iceman? Clues Emerge in a Very Cold Case
Metrics details. Earth scientists have devised many complementary and consistent techniques to estimate the ages of geologic events. Annually deposited layers of sediments or ice document hundreds of thousands of years of continuous Earth history. Gradual rates of mountain building, erosion of mountains, and the motions of tectonic plates imply hundreds of millions of years of change. Radiometric dating, which relies on the predictable decay of radioactive isotopes of carbon, uranium, potassium, and other elements, provides accurate age estimates for events back to the formation of Earth more than 4. Historians love to quote the dates of famous events in human history. They recount days of national loss and tragedy like December 7, and September 11, And they remember birthdays: July 4, and, of course, February 12, the coincident birthdays of Charles Darwin and Abraham Lincoln.
Ötzi the Iceman: scientists find 5,000-year-old blood sample
One image of Otzi The Iceman is the name given to the mummified body of a was found in near a glacier near the border of Italy and Austria. He is the best-preserved prehistoric man ever discovered with his own equipment and clothing. Most ancient human remains are found in burial chambers with carefully selected objected rather than what they use in everyday life.

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. So the real way to understand human genetics and migration is to time travel, and that is what ancient DNA has enabled us to do. Because of the ancient DNA revolution, we now know that major population changes and migrations happened over time. Ancient DNA research is now bringing new data to bear on these questions. One outcome from the new science is that we now know the people who built the passage tombs at Newgrange, Knowth and Dowth were not the same people we are today.
They were replaced by another group who arrived later.

Ötzi – a new understanding of the holy grail of glacial archaeology
In the early morning hours of February 27, , chemist Martin Kamen sat in a cold, dark police station. Police officers apprehended the disheveled scientist, too tired to protest, outside of his laboratory at the University of California, Berkeley and hauled him to the station for questioning. They accused him of committing a string of murders that took place the previous evening. After he was released, Kamen went home for a brief nap, returned to the lab, and then made one of the most important discoveries of the 20th Century: the carbon isotope.
If you want to understand anything related to biology, you start with carbon.
Scientists have recently discovered that Otzi’s last meal consisted of a few slices of fatty, cured goat meat, similar to modern-day bacon. But many.
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. This technique measures the amount of carbon in a dead organism, compares it to the carbon levels in the atmosphere today and gives an estimate of when the organism died.
Before Present, a time scale used in radiocarbon dating. This demonstrates to me that the desire to adorn and heal the body with tattoo is a very ancient part of our human past and culture. Thousands of ancient mummies exist around the world in museums and other collections that should be investigated further for tattoos, Krutak adds. In turn, we may see the antiquity of tattooing being pushed further and further back in time, which is an exciting prospect.
The cause of death remained uncertain until 10 years later, when an X-ray of the mummy pointed to foul play in the form of a flint arrowhead embedded in his back, just under his shoulder. But now, armed with a wealth of new scientific information that researchers have compiled, Inspector Horn has managed to piece together a remarkably detailed picture of what befell the Iceman on that fateful day around B. Most were ritually prepared, which usually meant removal of internal organs, preservation with chemicals or exposure to destructive desert conditions.
The more scientists learn , the more recognizable the Iceman becomes.

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.
The activities below are designed to help students connect with how people in the past lived and understand how scientists study people who lived hundreds and even thousands of years ago.

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.

Comparisons between the observed abundance of certain naturally occurring radioactive isotopes and their decay products, using known decay rates, can be used to measure timescales ranging from before the birth of the Earth to the present. For example measuring the ratio of stable and radioactive isotopes in meteorites can give us information on their history and provenance.
Radiometric dating techiques were pioneered by Bertram Boltwood in , when he was the first to establish the age of rocks by measuring the decay products of the uranium to lead. Carbon is the basic building block of organic compounds and is therefore an essential part of life on earth.
