Oldest evidence of arrows found
By Victoria Gill
Science reporter, BBC News
Researchers in South Africa have revealed the earliest direct evidence of human-made arrows.
The scientists unearthed 64,000 year-old “stone points”, which they say were probably arrow heads.
Closer inspection of the ancient weapons revealed remnants of blood and bone that provided clues about how they were used.
The team reports its findings in the journal Antiquity.
The arrowheads were excavated from layers of ancient sediment in Sibudu Cave in South Africa. During the excavation, led by Professor Lyn Wadley from the University of the Witwatersrand, the team dug through layers deposited up to 100,000 years ago.
Marlize Lombard from the University of Johannesburg, who led the examination of the findings. She described her study as “stone age forensics”.
“We took the [points] directly from the site, in little [plastic] baggies, to the lab,” she told BBC News.
“Then I started the tedious work of analysing them [under the microscope], looking at the distribution patterns of blood and bone residues.”
Because of the shape of these “little geometric pieces”, Dr Lombard was able to see exactly where they had been impacted and damaged. This showed that they were very likely to have been the tips of projectiles – rather than sharp points on the end of hand-held spears.
The arrowheads also contained traces of glue – plant-based resin that the scientists think was used to fasten them on to a wooden shaft.
“The presence of glue implies that people were able to produce composite tools – tools where different elements produced from different materials are glued together to make a single artefact,” said Dr Lombard.
“This is an indicator of a cognitively demanding behaviour.”
The discovery pushes back the development of “bow and arrow technology” by at least 20,000 years.
Researchers are interested in early evidence of bows and arrows, as this type of weapons engineering shows the cognitive abilities of humans living at that time. …
Professor Chris Stringer from the Natural History Museum in London said the work added to the view that modern humans in Africa 60,000 years ago had begun to hunt in a “new way”.
Neanderthals and other early humans, he explained, were likely to have been “ambush predators”, who needed to get close to their prey in order to dispatch them.
Professor Stringer said: “This work further extends the advanced behaviours inferred for early modern people in Africa.”
“But the long gaps in the subsequent record of bows and arrows may mean that regular use of these weapons did not come until much later.
“Indeed, the concept of bows and arrows may even have had to be reinvented many millennia [later].”

Traditionally, bows and arrows are supposed to mark the transition from the Palaeolithic to the Mesolithic, about 20,000 years ago.
Neanderthals supposedly did not even use spears for throwing, only for stabbing at short distance.
ScienceDaily (Sep. 21, 2010) — For decades scientists believed Neanderthals developed `modern’ tools and ornaments solely through contact with Homo sapiens, but new research from the University of Colorado Denver now shows these sturdy ancients could adapt, innovate and evolve technology on their own: here.

A recently announced discovery of sophisticated stone tools at the Pinnacle Point site in South Africa pushes further back in time the evidence for the appearance of modern human intellectual capacities, to at least 71,000 years ago. The discovery helps reduce what has been seen as a perplexing temporal gap of over 100,000 years between the earliest fossil remains of anatomically modern humans and the first appearance in the archaeological record of evidence that these people possessed the capability for fully abstract, symbolic thought, which is the basis of modern human technology, social organization, and culture at the beginning of the Upper Paleolithic period: here.
