The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
While Ötzi wore the oldest known leather shoes prior to this discovery (his were grassy socks held together with straps of bear and deer leather), 7,420-year-old sandals made from plant material were previously found in the Arnold Research Cave in Missouri.
The newly discovered lace-up moccasin is thought to narrowly pre-date the first known slip-on shoe, which is 4,680 radiocarbon years old.
Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
This was revised in the early 1960s to 5,730 years, which meant that many calculated dates in papers published prior to this were incorrect (the error in the half-life is about 3%).
The development of radiocarbon dating has had a profound impact on archaeology.
In addition to permitting more accurate dating within archaeological sites than previous methods, it allows comparison of dates of events across great distances.
Talk about vintage footwear—an international team of archaeologists has discovered the world's oldest leather shoe.
One thousand years older than the Great Pyramid of Giza in Egypt, the 5,500-year-old shoe was perfectly preserved by the cool, dry conditions in the sheep dung–lined cave in Armenia where it was found."We thought initially that the shoe and other objects were about 600 to 700 years old because they were in such good condition," Ron Pinhasi said in a prepared statement.
