But I'd go one step farther and argue that regardless of whether it is found to be the ancestor of Homo or a dead-end branch of humanity, the Malapa hominins are now the ones to beat. The skull and dentition of Au. And yet the A. sediba fossils manage to stand out from even this elite crowd, because of the sheer volume and quality of information they contain.

Previously the oldest known hominin tartar came from much younger Neandertals and early modern humans. Instead of belonging to the human lineage, the new species of Australopithecus sediba is more closely related to other hominins from South Africa that are on a side branch of the human family tree, according to a new analysis of the fossil presented here last week at the annual meeting of the American Association of Physical Anthropologists. Fossils in near-pristine condition, thus eliminating uncertainties about how pieces fit together? The Malapa site is an incredibly high-resolution time capsule. Au. The new Au. But critics have countered that A. sediba is not particularly Homolike overall and that it probably instead belonged to a South African lineage of hominins that ultimately went extinct--one of many dead-end branches in our family tree. But critics have countered that A. sediba is not particularly Homolike overall and that it probably instead belonged to a South African lineage of hominins that ultimately went extinct—one of many dead-end branches in our family tree. sediba, that important fact would be missed. Such skin features are themselves clues to the body's ability to offload excess heat, which became increasingly important as hominins became more active over the course of evolution.

This means A. sediba also has what is characteristic of humans and important for tool-making: a precision grip. Berger and his colleagues have argued from the beginning that A. sediba might well be the long-sought species that gave rise to our genus (or a close relative of that species). sediba, that important fact would be missed. So there you have it. Yahoo News Explains, What of 'Individual-1'? Any time human fossils, especially skeletons, are unearthed it’s a big deal, because such remains are so incredibly rare. Australopithecus sediba is the latest fossil find that is claimed to represent evolutionary human ancestors. And yet the A. sediba fossils manage to stand out from even this elite crowd, because of the sheer volume and quality of information they contain. Check. Hand bones from a single individual with a clear taxonomic affiliation are scarce in the hominin fossil record, which has hampered understanding the evolution of manipulative abilities in hominins.

Australopithecus sediba uniquely combines talocalcaneal joint morphology indicative of mobility with specializations of the talonavicular joint that provide medial midtarsal stabilization. A. SEDIBA ’ S HANDS As you can see in the picture of the hands, the thumb of A. sediba is much longer relative to the other fingers. To appreciate the importance of any given discovery, we must consider it in its historical context. Will enough people want it?

He has also sent out scores of replicas to institutions around the world, and routinely brings casts of the bones--even ones that his team has yet to formally describe--to professional meetings to share with other researchers. sediba has led to considerable debate over whether the Malapa hominins should be classified as Australopithecus or Homo [9,12,40,41]. CT scanning of some of the many chunks of rock blasted from the site by limestone miners back in the early 1900s has already revealed several bones. assuming that hypothesis is correct.
