A 2011 discovery in the Canadian province of New Brunswick discovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in some species by dendrochronology to make inferences about when a wooden object was created.

People have used wood for millennia for many purposes, primarily as a fuel or as a construction material for making houses, tools, weapons, furniture, packaging, artworks, and paper.Constructions using wood can date back even ten thousand years. Bulidings like the European Neolithic long house were made of primary of wood.

Recent use of wood has been changed by the addition of steel and bronze into construction.

The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the prevailing climate at that time.
