Neither chimpanzee nor human, Ardipithecus reveals the surprising ancestry of both.
Australopithecus fossils were regularly interpreted during the late 20th century in a framework that used living African apes, especially chimpanzees, as proxies for the immediate ancestors of the human clade. Such projection is now largely nullified by the discovery of Ardipithecus. In the context of accumulating evidence from genetics, developmental biology, anatomy, ecology, biogeography, an...

www.sciencemag.org SCIENCE VOL 326 18 DECEMBER 2009 1581 COVER Ardipithecus ramidus, a possible human ancestor, inhabited then-wooded regions of Ethiopia 4.4 million years ago. This year, studies of the fossilized skeleton of a member of the species raised surprising questions about how key human traits evolved. See the Breakthrough of the Year special section beginning on page 1598 and at www....
متن کاملHomoplasy and homology: dichotomy or continuum?
Homology is the presence of the same feature in two organisms whose most recent common ancestor also possessed the feature. I discuss the bases on which we can tell that two features being compared share sufficient elements of sameness to allow them to be treated as homologous and therefore to be legitimately compared with one another in a way that informs comparative, evolutionary, and phyloge...
متن کاملDeveloping the Conceptual and Methodological Framework for Discursive-institutional Analysis of Coastal Exclusive Space Production: with Special Reference to Critical Realism Perspective
Because of the limited capacity of coastal lands and conflicting interests among stakeholders for coastal resources, there are intensifying pressures to retain and provide more public access to the coast. Coastal gated communities have been developed increasingly in the middle shoreline of Caspian Sea in North of Iran. They are kind of exclusive space production as they restrict public access t...
متن کاملComprehensive Analysis of Chimpanzee and Human Chromosomes Reveals Average DNA Similarity
Since the original 2005 report for the chimpanzee (chimp) genome assembly (5X rough draft), an additional one-fold redundant coverage has been added. Using the new 6X chimpanzee assembly, a sequential comparison to the human genome was performed on an individual chromosome basis. The chimpanzee chromosomes, were sliced into new individual query files of varying string lengths and then queried a...
