Humans were building structures from wood earlier than had been thought possible, according to archaeologists who have uncovered evidence from almost half a million years ago.
Researchers from the University of Liverpool and Aberystwyth University, whose findings have been published in the journal Nature, reported on the excavation of well-preserved wood, thought to date back at least 476,000 years and pre-date the evolution of homo sapiens, at a site in Kalambo Falls, Zambia.
