Along the banks of the Kalambo River in Zambia near Africa's second-highest waterfall, archaeologists have excavated two logs of the large-fruited bushwillow tree that were notched, shaped and joined about half a million years ago.
These artefacts, researchers said on Wednesday, represent the oldest-known example of humans – in this case a species that preceded our own – building wooden structures, a milestone in technological achievement that indicates that our forerunners displayed more ingenuity than previously thought.
The logs, modified using stone tools, appear to have been part of a framework for a structure, a conclusion that contradicts the notion humans at that time simply roamed the landscape hunting and gathering resources.
"The framework could have supported a walkway or platform raised above the seasonally wet surroundings. A platform could have multiple purposes including storage of firewood, tools, food and as a foundation on which to place a hut," said archaeologist Larry Barham of the University of Liverpool in England, lead author of the study published in the journal Nature.
"Not only did the working of trees require considerable skill, the right tools and planning, the effort involved suggests that the makers were staying in the location for extended periods, whereas we have always had a model of Stone Age people as nomadic," Barham added.
The rarity of wood preservation at early archaeological sites – it is perishable over time – means scientists have little understanding of how early humans used it.
"While the vast majority of archaeological sites of this age preserve only the stone tools, Kalambo Falls provides us a unique insight into the wooden objects that these tools were being used to create, allowing us a much richer and more complete picture of the lives of these people," said geographer and study co-author Geoff Duller of Aberystwyth University in Wales.
"Wood can be shaped into a variety of forms making it an excellent construction material that is strong and durable," Barham added.
The earliest-known Homo sapiens fossils date from about 300,000 years ago in Morocco. The Kalambo Falls logs were determined to be from about 476,000 years ago.
No human remains were found there, but Barham suspects the artefacts were fashioned by a species called Homo heidelbergensis, known from about 700,000 to 200,000 years ago. Homo heidelbergensis possessed a large browridge and a bigger braincase and flatter face than earlier hominins species on the human evolutionary lineage.
The overlying log at Kalambo Falls is about 1.4 metres long, with tapering ends and about 1.5 metres of the underlying log was excavated.
"The structure involves the intentional shaping of two trees to create a framework of two interlocking supports. A notch was cut into the overlying log and the underlying tree was shaped to fit through the notch. This arrangement prevents the overlying log from moving side to side, giving stability to the structure," Barham said.
The wood, found in a waterlogged condition, was preserved by a permanent high-water table at the site. Clay sediments surrounding it provided an oxygen-free environment preventing decay.
The earliest-known wood artifact is a plank fragment from Israel, about 780,000 years old. Wooden tools for foraging and hunting are known from about 400,000 years ago. A wedge-shaped wooden tool about as old as the logs was found at Kalambo Falls.
The site, about 400 metres upriver from a spectacular 235-metre-high waterfall, was discovered in 1953, but its age remained unclear. The new study used a method called luminescence dating, measuring the amount of energy an object has trapped since it was buried.
"The finds from Kalambo Falls indicate that these hominins, like Homo sapiens, had the capacity to alter their surroundings, creating a built environment," Barham said. "Use of wood in this way suggests the cognitive ability to these early humans was greater than we have believed based on stone tools alone."

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Three ways to limit your social media use
Clinical psychologist, Dr Saliha Afridi at The Lighthouse Arabia suggests three easy things you can do every day to cut back on the time you spend online.
1. Put the social media app in a folder on the second or third screen of your phone so it has to remain a conscious decision to open, rather than something your fingers gravitate towards without consideration.
2. Schedule a time to use social media instead of consistently throughout the day. I recommend setting aside certain times of the day or week when you upload pictures or share information.
3. Take a mental snapshot rather than a photo on your phone. Instead of sharing it with your social world, try to absorb the moment, connect with your feeling, experience the moment with all five of your senses. You will have a memory of that moment more vividly and for far longer than if you take a picture of it.
Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.
