Skeleton of early human ancestor discovered in rock

Washington, July 13 (ANI): A discovery of a large rock containing significant parts of a skeleton of an early human ancestor will be announced on Friday, 13 July 2012.

The skeleton is believed to be the remains of 'Karabo', the type skeleton of Australopithecus sediba, discovered at the Malapa Site in the Cradle of Humankind in 2009.

Professor Lee Berger from the Wits Institute for Human Evolution based at the University of the Witwatersrand in Johannesburg will make the announcement at the Shanghai Science and Technology Museum in Shanghai, China on Friday, 13 July 2012 at 09:00 South African standard time.

Professor Lee Berger, a Reader in Palaeoanthropology and the Public Understanding of Science at the Wits Institute for Human Evolution, is visiting China as part of a South African delegation promoting trade, business and tourism relations between the two competitive city regions, Gauteng and Shanghai.

"We have discovered parts of a jaw and critical aspects of the body including what appear to be a complete femur (thigh bone), ribs, vertebrae and other important limb elements, some never before seen in such completeness in the human fossil record," said Berger.

"This discovery will almost certainly make Karabo the most complete early human ancestor skeleton ever discovered. We are obviously quite excited as it appears that we now have some of the most critical and complete remains of the skeleton, albeit encased in solid rock. It's a big day for us as a team and for our field as a whole," he noted.

The remains are invisible to the casual observer and are entrenched in a large rock about one metre in diameter. It was discovered almost three years ago, but lay unnoticed in the Wits laboratories until early last month.

Prof. Berger and his wife Jackie Smilg, a radiologist at the Charlotte Maxeke Hospital, who is conducting her PhD on the CT scanning of fossil material embedded in rock, scanned the large rock in a state of the art CT scanner.

In an unprecedented gesture of open access to science and public participation, the University of the Witwatersrand, the Gauteng Provincial Government and the South African national government announced that for the first time in history, the process of exploring and uncovering these fossil remains would be conducted live, captured on video, and conveyed to the world in real time. This will allow members of the public and the scientific community to share in the unfolding discovery in an unprecedented way.

A laboratory studio, designed in collaboration with the National Geographic Society, will be built at the Maropeng Visitor Centre in the heart of the Cradle of Humankind World Heritage Site. It will allow the public to view the preparation of this skeleton live if they visit Maropeng, or live on the internet.

"The public will be able to participate fully in Live Science and future discoveries as they occur in real time - an unprecedented moment in palaeoanthropology. The laboratory studio will be also linked to laboratories at Wits University and the Malapa site," said Berger.

Access to the laboratory studio will not be limited only to visitors to the Cradle of Humankind and the internet. "We intend to create virtual 'outposts' in major partner museums around the world," noted Berger.

"These outposts will allow visitors to these partner museums the chance to interact with scientists in real time in a way we simply could not conceive of a few years ago. It is anticipated that the laboratory and virtual infrastructure will be built within a year, expanding our ambitious tourism and smart province infrastructure programme," he said.

Berger adds that negotiations have begun with the Shanghai Science and Technology Museum, the Natural History Museum in the United Kingdom and the Smithsonian in Washington. (ANI)
