Apr. 11, 2013 ? A dental study of fossilized remains found in South Africa in 2008 provides new support that this species is one of the closest relatives to early humans.
The teeth of this species -- called Australopithecus sediba -- indicate that it is also a close relative to the previously identified Australopithecus africanus. Both of these species are clearly more closely related to humans than other australopiths from east Africa, according to the new research.
The study, published in the journal Science, revealed that both africanus and sediba shared about the same number of dental traits with the first undeniably human species.
"Our study provides further evidence that sediba is indeed a very close relative of early humans, but we can't definitively determine its position relative to africanus, said Debbie Guatelli-Steinberg, co-author of the study and professor of anthropology at The Ohio State University.
The research was led by Joel D. Irish, professor of natural sciences at Liverpool John Moores University.
The sediba fossils were found in South Africa in 2008 and first described in a series of articles published in Science in 2010. That study was led by Lee Berger of the University of Witwatersrand in South Africa, who is also a co-author of this new study.
In this study, Irish, Guatelli-Steinberg and their colleagues extended that work by examining the teeth from sediba and comparing them to eight other African hominin species, which include modern humans from Africa, and extinct species of Homo, Australopithecus, and Paranthropus. In all, the researchers examined more than 340 fossils and 4,571 recent specimens. They also examined teeth from 44 gorillas for comparison.
The focus was on 22 separate traits of tooth crowns and roots that can give clues as to the relationship between the different species studied.
For example, they measured how much one of the incisors was shovel-shaped. Depending on the species in this study, the incisor may have no depression in the back of the tooth, a faint shovel shape, or a trace of that shape.
Researchers use standardized measurements from the Arizona State University Dental Anthropology System to compare the teeth on these 22 traits.
The researchers found that on 15 of these traits, sediba and africanus scored the same. Sediba shared 13 traits with Homo erectus, an early human species, which was comparable to how africanus scored.
Sediba and africanus shared five dental traits that weren't found in earlier australopiths, further showing their close relationship. Both also share five traits with early humans -- Homo habilis/rudolfenis and Homo erectus -- which weren't shared with earlier ancestors, demonstrating the close relationship between these two australopiths and the first humans.
Teeth are an excellent way to study relationships between different species, Guatelli-Steinberg said. They are well preserved in the fossil record, and researchers can compare large samples, at least for many ancient species.
In addition, most of the dental traits the researchers used in this analysis don't have a selective advantage that could help one species survive over another. That means if researchers see a similar trait in two species, they can be more confident that they shared a common ancestor and that the trait didn't evolve independently.
In many ways, these new dental data support the earlier research on sediba, which included analysis of the inside of the skull, hand, spine, pelvis, foot and ankle, Guatelli-Steinberg said.
"All of the research so far shows that sediba had a mosaic of primitive traits and newer traits that suggest it was a bridge between earlier australopiths and the first humans," she said.
Guatelli-Steinberg said their dental analysis showed that both africanus and sediba are more closely related to humans than the famous "Lucy" skeleton fossil found in East Africa in 1974. This fossil represented a species, Australopithecus afarensis, that was at one time was thought to be the closest relative of humans.
Lucy is estimated to have lived 3.2 million years ago. Sediba lived 1.977 million years ago, while africanus lived between 3.03 and 2.04 million years ago.
"Our research on teeth can't definitively settle if either sediba or africanus is more closely related to humans than the other species," Guatelli-Steinberg said. "But our findings do suggest that both are closely related to each other and are more closely related to humans than afarensis.
"We need to find more sediba remains to help fill in the missing pieces of this evolutionary puzzle."

It looks like Intel's planning on bringing its Next Unit of Computing (NUC) mini-computer upmarket, if a leaked roadmap from ComputerBase.de is to be believed. The documents look highly tentative, but if they come to fruition then Intel will start offering new NUCs (code-named "Skull Canyon" and "Horse Canyon") with Intel Core i7-3537U and Core i5-3427U processors along with its current Core i3 model during the first half of the year. New motherboards would be used that alter the slot configurations substantially: the Thunderbolt connector would be dropped in favor of USB 3.0 -- three on the i7 model, one on the i5 -- with DisplayPort 1.1a added to each along with HDMI 1.4a connectors. There's no pricing yet, but we found that you'd need to nearly double the price of the original NUC to create a working computer, so bear that in mind when you're looking at the leaked slides after the break.

UNITED NATIONS (Reuters) - The United States boycotted as "inflammatory" a meeting on international justice on Wednesday organized by a Serbian politician who heads the U.N. General Assembly - a session some nations say was intended merely to complain about the treatment of Serbs in war crimes tribunals.
The meeting and panel discussion were set up by former Serbian Foreign Minister Vuk Jeremic, who is serving as president of the 193-nation assembly. Some U.N. diplomats have privately accused Jeremic of using the General Assembly to promote his own career and his home country.
European and other Western nations have said Wednesday's session on international justice was a thinly veiled attempt to attack the international war crimes tribunal for the former Yugoslavia, which Serbia has criticized. Jordan and Canada joined the United States in boycotting the debate.
"The United States strongly disagrees with the decision of the president of the General Assembly to hold an unbalanced, inflammatory thematic debate today on the role of international criminal justice in reconciliation and will not participate," said Erin Pelton, spokeswoman for the U.S. mission to the United Nations.
"We believe that ad hoc international criminal tribunals and other judicial institutions in Rwanda, the former Yugoslavia, Sierra Leone and Cambodia have been critical to ending impunity and helping these countries chart a new, more positive future," Pelton said in a statement.
Pelton added that it was especially problematic that the day's events "fail to provide the victims of these atrocities an appropriate voice."
A senior Western diplomat said on condition of anonymity that Jeremic's decision to organize the meeting on April 10 - the day that Croatia's Nazi puppet state was established in 1941 - ensured that the "whole event took on a Serbian feel."
He added that Jeremic had refused to change the date after he was requested to do so by a number of delegations.
'ALMOST AN IMPEACHABLE OFFENSE'
Jordan's U.N. Ambassador Prince Zeid Ra'ad Zeid al-Hussein told a small group of reporters that Serbia's approach to the session on international justice was "almost an impeachable offense" - ostensibly referring to Jeremic's largely ceremonial post as the head of the General Assembly.
Since it was set up in 1993, the war crimes tribunal for the former Yugoslavia has indicted 161 people for crimes stemming from the wars that shattered the Yugoslav federation, of whom 15 have been acquitted. Several dozen suspects remain on trial.
Serbia and its ally Russia have sharply criticized the tribunal over recent decisions to free two Croatian generals and a Kosovo Albanian former guerilla commander.
Jeremic did not explicitly attack the Hague war crimes tribunals in his speech, though he told the assembly that international justice could be misused in a way that prevents reconciliation between former adversaries.
"Such outcomes would harm efforts to strengthen the rule of law, for no legal tradition recognizes the guilt or innocence of an entire nation," he said.
U.N. Secretary-General Ban Ki-moon defended the war crimes tribunals, the International Criminal Court (ICC) and other methods of ensuring accountability.
"The system of international criminal justice has ... given voice to victims and witnesses," Ban said.
Serbian President Tomislav Nikolic hammered away at the Hague tribunal in a roughly 45-minute speech to the assembly, telling participants that the "prosecution has been favored over the defense" and the court was guilty of the "most flagrant violation of human rights."
Richard Dicker of Human Rights Watch said Nikolic is well known as a denier of the Srebrenica genocide. More than 8,000 Bosnian Muslim men and boys were killed in the Bosnian town of Srebrenica in July 1995 by Bosnian Serb forces under the command of Ratko Mladic, who is currently on trial for crimes against humanity and other war crimes.
Jordan, Britain and others complained that the victims of Srebrenica had no voice in Wednesday's debate.
Croatian Ambassador Ranko Vilovic also criticized the session, saying "truth, justice and reconciliation were not the values for which this debate was organized."
Some diplomats say Jeremic may be jostling to become the next president of Serbia. If he does not get Serbia's presidency, he is likely to try to become the next U.N. secretary-general, a position that is expected to be filled by an Eastern European, envoys say.
U.N. diplomats say Jeremic's name has been mentioned as a possible candidate to replace Ban after his term ends in December 2016. While Russia would support Jeremic, U.N. diplomats said there are less divisive candidates from Slovakia, Slovenia, Bulgaria and elsewhere.
The European Union's 27 member nations are attending the event but sending junior diplomats.

The Euphanerops sported bizarre fins below its anus, revealing some of the odd turns evolution took on the path to vertebrate evolution.
By Tia Ghose, LiveScience
A 370-milion-year-old, primitive fish sported a weird pair of fins just below its anus, new research shows.
The strange appendages, detailed Tuesday in the journal Biology Letters, were found on an ancient jawless fish called Euphanerops longaevus that lived around the time that jawless fishes like lampreys split off from jawed vertebrates, which include everything from sharks to humans.
"What's weird about this organism is that it had a paired anal fin. It's unique ? no other known fossil or modern fish is known to have that disposition," said study co-author Robert Sansom, a paleontologist at the University of Manchester in the U.K.
The findings suggest that early in primitive vertebrates' history, evolution experimented with a number of wacky body plans, only some of which survived, Sansom told LiveScience. [Image Gallery: The Freakiest Looking Fish]
Early fish
The Euphanerops fish were 3.9 inches long and looked somewhat like modern-day eels. The specimens were unearthed in a fossil bed in Miguasha, Quebec, decades ago, and were stored in collections in the National History Museum in London and the Museum d'Histoire Naturelle, Miguasha, in Quebec.
Previously, researchers weren't sure exactly what to make of the creatures' weird fins. Some thought the anal appendages might actually have been displaced from another part of the animal's body in the fossilization process.
Early body plan
The researchers weren't convinced of the displacement explanation. By comparing the 3-D surfaces of the fossil under a microscope, the team concluded that the fin pair was actually located below the anus on the living creature. Though it's not clear exactly how the fins were used, the fins most likely helped the fish get around, Sansom said.
The fossil dates to a critical period of vertebrate evolution: Jawed and jawless vertebrates diverged roughly around this time. Eventually jawed fish developed paired fins (but not anal fins) that evolved to become arms and legs. In fact, the same genes code for shark fins and human limbs.
The discovery changes the view of how fishes were evolving at this time, Sansom said.
"Rather than gradual acquisition of complex characteristics, maybe there was a bit more experimentation and odd acquisitions," he said.
Specialized trait?
The finding of paired anal fins is "beautifully illustrated," said Michael Coates, a vertebrate paleontologist at the University of Chicago, who was not involved in the study.
"It might just be the first vestige, it might be some kind of precursor to generating paired fins" that are commonly seen throughout jawed vertebrates, Coates told LiveScience.
But it's also possible they were a specialized trait that only Euphanerops possessed, not reflective of the evolutionary history of jawed vertebrates as a whole, Coates said.
