World's oldest wooden structure discovered in Zambia, dating back 476,000 years, archaeologists say Archaeologists say they have unearthed the oldest wooden structure ever discovered, dating from nearly half a million years ago, which suggests that our ancestors may have been more advanced than previously thought.

The exceptionally well-preserved wooden structure was found at Kalambo Falls in the north of Zambia, near the border with Tanzania.

It dates back at least 476,000 years, well before the evolution of Homo sapiens, according to a study describing the find in the journal Nature.

The wood bears cut-marks showing that stone tools were used to join two large logs to make the structure, which is believed to be a platform, walkway or raised dwelling to keep our relatives above the water.

The ancestors of humans were already known to use wood at this time, but for limited purposes such as starting a fire or hunting.

Larry Barham, an archaeologist at the UK's University of Liverpool and the study's lead author, told AFP that to his knowledge the previous record-holder for oldest wooden structure dated back around 9,000 years. (read on)
