Modified logs dating to about 476,000 years ago might be the oldest evidence of wooden structures, a new study finds.

Wooden artifacts decompose easily and are relatively scant in the archaeological record compared with stone or bone. The new finding, reported September 20 in Nature, suggests that the structural use of wood may stretch far back into the history of human ancestors, hinting at advanced cognitive skills and a less nomadic lifestyle for some hominids than previously thought.
