@pitochk: Wood may be one of the rarest materials in the universe. We see it everywhere, so that sounds strange. But for wood to exist, there must be life, the right conditions, and a long history of evolution. So far, Earth is the only place where we know trees exist. It’s hard to imagine how humanity would have developed without it. Wood is strong enough to build a house, yet soft enough to shape with simple stone tools. It can be split, carved, drilled, bent, and joined. Long before complex machines, it gave people a way to turn ideas into useful things. People made tool handles, boats, wheels, looms, and early machines from wood. It provided warmth and fuel for cooking. Later, charcoal helped people reach the temperatures needed to work metal. Even as new technologies appeared, wood continued to make them possible. We call much of our past the Stone Age, partly because stone survives better. Wooden objects usually decay, taking part of the story of human ingenuity with them. That makes the discovery of wooden structures around 476,000 years old even more remarkable. Our ancestors were already shaping and joining logs. Wood itself is an intricate material shaped by nature. Cellulose fibres help it resist pulling forces, while lignin gives it rigidity. Together, they form a trunk that can support its own weight and withstand the wind for years. Humans learned to use these properties long before they could explain them. #Wood #Nature #HumanHistory #edit #tree
