Read a special issue of Science in which all 11 landmark articles, an editorial, a news story, and multimedia materials are free and available without subscription. Probable life appearance of "Ardi," a drawing based on a partial fossilized skeleton from a female Ardipithecus ramidus who weighed about about 50 kilograms (110 pounds) and stood about 120 centimeters /2009/1001sp_ardi.shtml Before “Lucy,” There Was “Ardi”: First Major Analysis of One of Earliest Known Hominids Published in Science In a special issue of Science , an international team of scientists has for the first time thoroughly described Ardipithecus ramidus , a hominid species that lived 4.4 million years ago in what is now Ethiopia. This research, in the form of 11 detailed papers and more general summaries, was published today in the journal's 2 October 2009 issue. Science is published by AAAS, the nonprofit science society. The package of research offers the first comprehensive, peer-reviewed description of the Ardipithecus fossils, which include a partial skeleton of a female, nicknamed “Ardi.” Publication of the new research was the subject of simultaneous news conferences today in the Ethiopian capital of Addis Ababa, and at AAAS/ Science headquarters in Washington, D.C., with major international news media quickly conveying the story to a worldwide audience. “What we celebrate here today are the results of a scientific mission to the very deep past,” said Tim White of the University of California Berkeley, one of the lead authors of the research, at the AAAS news conference. The discovery and publication of the research is “an extraordinary event,” Samuel Assefa, Ethiopian ambassador to the United States, said at AAAS. “The deeper point for all of us is a deeper sense of our interconnectedness.” Alan I. Leshner, chief executive officer of AAAS and executive publisher of Science , called the publication “truly a landmark event in our understanding of human origins.” The last common ancestor shared by humans and chimpanzees is thought to have lived six million or more years ago. Though Ardipithecus is not itself this last common ancestor, it likely shared many of this ancestor's characteristics. For comparison, Ardipithecus is more than a million years older than “Lucy,” the partial female skeleton of Australopithecus afarensis . Until the discovery of the new Ardipithecus remains, the fossil record contained scant evidence of other hominids older than Australopithecus .
