Interesting indeed. And for a news website, some refreshingly sensible comments at the bottom:

"It always perplexes me that we're surprised by every new revelation of the sophistication of mesolithic and neolithic people. After all, they were no different, anatomically or intellectually, than 21st century humans. They may not have made all the discoveries that we've made in the last 10,000 years, but they were certainly as intellectually curious as we are."
