Ardipithecus ramidus

In its 2 October 2009 issue, Science presents 11 papers, authored by a diverse international team, describing an early hominid species, Ardipithecus ramidus, and its environment. These 4.4 million year old hominid fossils sit within a critical early part of human evolution, and cast new and sometimes surprising light on the evolution of human limbs and locomotion, the habitats occupied by early hominids, and the nature of our last common ancestor with chimps.

Science is making access to this extraordinary set of materials FREE (non-subscribers require a simple registration). The complete collection, and abridged versions, are available FREE as PDF downloads for AAAS members, or may be purchased as reprints.
