Riffing on my last post, I can’t help but wonder if there’s something that we lose track of too easily. We really have no idea of the state of technology in the very distant past. We’ve deduced what life was like 3,000 or 5,000 or 10,000 years ago based on the presence or absence of implements made of bone, stone, pottery, and metal, the vestiges of things that have lasted over the millennia. However, there may well have been things made of leather, wood, basketry, and cloth of enormous complexity and sophistication. Those things have vanished.
There are some reasons to believe that’s true based, for example, on the design of pottery which makes little sense as pottery but makes a good deal of sense if the shards we’ve found were made in imitation of the design of baskets. But we’ll never really know.
