Unveiling the Oldest Known Footwear: A 100,000-Year-Old Mystery
Written on
Chapter 1: Ancient Footprints in South Africa
Recent discoveries in South Africa have revealed trails trodden by humans potentially dating back over 100,000 years. These early inhabitants likely wore some form of footwear, possibly sandals, suggesting they did not walk barefoot.
The rarity of such finds from this prehistoric era cannot be overstated. Determining when humans first donned footwear remains a mystery, largely because the oldest shoes were constructed from organic materials like leather and plant fibers, which have long since decayed. Most evidence of footwear only emerges from excavations of medieval urban centers.
Section 1.1: The Role of Ichnology in Archaeology
Ichnology, a specialized branch of paleozoology that studies fossilized animal traces, has provided valuable insights to researchers in South Africa. This methodology was employed to examine human footprints uncovered in locations like the Garden Route National Park, Goukamma Reserve, and the Kleinkrantz area along the coast.
Surprisingly, while the imprints were undoubtedly human, there were no visible toes, leading scientists to conclude that the individual must have been wearing shoes. They theorized the existence of some form of sandals.
Subsection 1.1.1: Reconstructing Prehistoric Footwear
To gain a better understanding of the footwear in question, researchers undertook a comprehensive investigation. This involved studying traditional San sandals from the Kalahari Desert, analyzing museum specimens, examining depictions of footwear in San rock art, and exploring the oldest extant footwear samples. Experimental work on beaches confirmed that the footprints were made by someone wearing sandals with a rigid sole.
Section 1.2: Dating the Footprint Imprints
Determining the age of these imprints posed a significant challenge. Archaeologists typically rely on radiocarbon dating for artifacts; however, in this case, they were dealing with the impression left by a foot rather than an object itself. By comparing it to other prints in the vicinity, they estimated the shod individual's footprints to be between approximately 70,000 and 130,000 years old.
If validated, these would represent the world's oldest known shod footprints, with only four other archaeological sites yielding similar finds, one potentially left by Neanderthals. “While the evidence is not definitive, we are thrilled with our findings. They bolster the notion that South Africa was a cradle for human cognitive and practical skill development long ago,” states Charles Helm from the African Centre for Coastal Palaeoscience at Nelson Mandela University.
Chapter 2: The World's Oldest Sandals
So far, the oldest known sandals date back about 10,000 years and were discovered in Fort Rock, Oregon. Made from bark and other plant materials, these sandals survived due to being buried under volcanic ash from the Mazama volcano thousands of years ago. Numerous sandals were found in varying conditions at this site, including some for children and others that were heavily worn, indicating they were likely discarded. The oldest complete footwear in the United States is also estimated to be around 7,500 years old.
In Europe, an intriguing find includes the shoes of Ötzi, the famous Iceman, who lived approximately 5,300 years ago in the Alps between Italy and Austria. Ötzi's footwear was crafted from various materials, featuring a bear leather sole and deer leather uppers secured with cow leather straps.
