The Official Google Blog explains today that they made it possible to find something definitely not digital. The post titled “Google Earth helps discover rare hominid ancestor in South Africa” explains:
Back in March 2008, Professor Lee Berger from Witswatersrand University in Johannesburg started to use Google Earth to map various known caves and fossil deposits identified by him and his colleagues over the past several decades, as it seemed the ideal platform by which to share information with other scientists. In addition, he also used Google Earth to locate new fossil deposits by learning to identify what cave sites looked like in satellite images.
At the beginning of this project, there were approximately 130 known cave sites in the region and around 20 fossil deposits. With the help of the navigation facility and high-resolution satellite imagery in Google Earth, Professor Berger went on to find almost 500 previously unidentified caves and fossil sites, even though the area is one of the most explored in Africa. One of these fossil sites yielded the remarkable discovery of a new species, Australopithecus sediba. This species was an upright walker that shared many physical traits with the earliest known species of the genus homo — and its introduction into the fossil record might answer some key questions about our earliest ancestry in Africa. . . .
