I wrote about the fascinating archaeological project under way at Rising Star Cave in South Africa. Gazing through a narrow crack in the back of the cave, explorers saw bones, including what appeared to be human bones, in a chamber beyond. Since the cave was in a national park, dynamiting the opening was out of the question. So South African anthropologist Lee Berger put out a call for people skinny enough to fit through a 7-inch crack, with experience in both caving and excavation. Amazingly, he found half a dozen young women who fit the bill. They began excavating in the cave, using a constant video feed to keep their middle aged bosses in the loop as to what was going on. All of this was chronicled on a blog at National Geographic, rather than the usual semi-secret arrangement designed to protect publication rights.
Now the team has published their main findings, and they are keeping to their open ethos by putting them up on eLife where anybody can read them.
The excavators think that this chamber was always accessible only through the narrow opening, and that nobody ever lived there. The bodies were pushed into it through the crack, which the excavators think was done as an intentional burial rite. Which would push such behavior back more than a million years.
