Oldest-known fiber materials discovered in Georgia

A team of archaeologists and paleobiologists has discovered flax fibers that are more than 34,000 years old, making them the oldest fibers known to have been used by humans. The fibers, discovered during systematic excavations in a cave in the Republic of Georgia, are described in this week's issue of Science. The flax, which would have been collected from the wild and not farmed, could have been used to make linen and thread, the researchers say. The cloth and thread would then have been used to fashion garments for warmth, sew leather pieces, make cloths, or tie together packs that might have aided the mobility of our ancient ancestors from one camp to another.
     The excavation was jointly led by Ofer Bar-Yosef, George Grant MacCurdy and Janet G. B. MacCurdy Professor of Prehistoric Archaeology in the Faculty of Arts and Sciences at Harvard University, with Tengiz Meshveliani from the Georgian State Museum and Anna Belfer-Cohen from the Hebrew University. The microscopic research of the soil samples in which numerous flax fibers were discovered was done by Eliso Kvavadze of the Institute of Paleobiology, part of the National Museum of Georgia. The items created with these fibers increased early humans chances of survival and mobility in the harsh conditions of this hilly region. The flax fibers could have been used to sew hides together for clothing and shoes, to create the warmth necessary to endure cold weather. They might have also been used to make packs for carrying essentials, which would have increased and eased mobility, offering a great advantage to a hunter-gatherer society.
     Some of the fibers were twisted, indicating they were used to make ropes or strings. Others had been dyed - black, gray, turquoise and even pink.. Early humans used the plants in the area to color the fabric or threads made from the flax. Today, these fibers are not visible to the eye, because the garments and items sewed together with the flax have long ago disintegrated. Bar-Yosef, Kvavadze and colleagues discovered the fibers by examining samples of clay retrieved from different layers of the cave under a microscope.
     "I mean, talk about the proverbial needle in the haystack. Trying to find fibers that are 30,000 years old really is almost impossible," Elizabeth Barber, a retired professor from Occidental College in Los Angeles, said. Barber says evidence of textiles already dates back 25,000 years - there are impressions of woven material found in clay. It's now clear that the technology is even older. And that fits nicely with her hypothesis that plain old string was a powerful technology, which helped people weather the last ice age.
     The scientists' original goal was to analyze tree pollen samples found inside the cave, part of a study of environmental and temperature fluctuations over the course of thousands of years that would have affected the lives of these early humans. However, while looking for this pollen, Kvavadze, who led the analysis of the pollen, also discovered non-pollen polymorphs - these flax fibers.
     Bar-Yosef and his team used radiocarbon dating to date the layers of the cave as they dug the site, revealing the age of the clay samples in which the fibers were found. Flax fibers were also found in the layers that dated to about 21,000 and 13,000 years ago. Bar-Yosef's team began the excavations of this cave in 1996, and has returned to the site each year to complete this work.
