Tomorrow in the journal Science eleven papers by 47 authors from 10 countries will describe the analysis of a discovery made in 1992. That discovery may help solve the problem of how the ancestral line that led to humans split from the the line that led to chimpanzees for which there has been virtually no evidence until now. It may be that the newest creature, Ardipithecus ramidus (Ardi), which predates the widely know "Lucy" (Australopithecus afarensis) by over one million years is in our lineage from the common ancestor between chimps and humans. The discovery made near where Lucy was found suggests that continued research in that part of Ethiopia could lead to that last common ancestor of humans and chimps. This also shows the deliberate slowness of scientific discovery, 17 years of research, peer review and debate before a joint announcement is made. Another missing link in the long list of missing links that creationists claim don't exist.
