Geologists Find Where Some Stonehenge Rocks Came From, Debunking Old Research (cnn.com)
Slashdot reader schwit1 shares a report from CNN: A team of 12 geologists and archaeologists from across the United Kingdom unveiled research this month that traces some of the prehistoric monument's smaller stones to two quarries in western Wales. The team also found evidence of prehistoric tools, stone wedges and digging activity in those quarries, tracing them to around 3000 BC, the era when Stonehenge's first stage was constructed. It's rock-solid evidence that humans were involved in moving these "bluestones" to where they sit today, a full 150 miles away, the researchers say. "It finally puts to rest long-standing arguments over whether the bluestones were moved by human agency or by glacial action," University of Southampton Archeology Professor Joshua Pollard said in an email. Slashdot reader schwit1 adds: "This leaves the question of how..."
The new parts aren't quoted or are understated.
1. We already knew about the quarries, what we didn't have were the actual tools used. We now have them, including wooden items.
2. We already knew about how they could have moved the stones, they're smaller and lighter than sarsens, we didn't know the route. We now know some were transported overland.
3. We didn't know if the stones were quarried specifically for Stonehenge or for a circle in Wales that was dismantled and recycled. We now know it was the former.
The real mystery is why people make a mystery of the known, when the unknown is potentially more interesting.

It's basically the same reason that people still compete for the world's tallest building and for breaking Guinness's silly world records--because we can. I always cringe at documentaries that try to come up with silly explanations, including space aliens, because it's amazing that we still don't understand ourselves. Humans have always been symbolic creatures--not mere practical creatures--and so we do things because we feel them to be meaningful, not simply because we think they might be useful.
