The British "Nature" magazine has published an article written by Michael Brune, the University of Purijie University, and said that the biocent stone found in the same year is human fossil, and it is later Scientists called the saliva of Sahar, which also proved that the Sahar people are the ancient ancestors of humans.
In 2002, Michelle Brula and other researchers found a biological skull, jaw fragment and some scattered teeth known as "Mai" in Africa. These fossil ages are around 6 million to 7 million years.
The study found that in the evolution tree map, the species had an important branch in this period, and a branch finally evolved into modern human beings, while the other branch evolved into chimpanzee. The researchers called this life as a Sahar people, and concluded that the Sahar people belong to the earliest human.
At the same time, another scientist believes that the Sahar's skull has both human character and has chimpanzee characteristics. Therefore, it is called "a wheelbarrow filled with a problem." New evidence has increased the possibility of Sahar people as the primitive, but still can't make final judgment.
At present, the biggest controversial problem is whether the Sahar people walk together. Because this is a key feature of the primitive. In this regard, Brun said in an email, under the existing evidence, if the Sahar people are not working together, they will "surprise". But he agreed that finally, conclusions still need to continue to find and analyze the fossil evidence of upright walking, such as knee, hip bone or foot bone.
Brune and his colleagues said in the article that two new jaw fragments and a binding crown were found in the place where Sahar fossil was originally found. Analysis shows that these fossils are similar to the original fossils, while different from the fossils.
Since fossils are deformed underground, they also provide a computer replicated skull. The researchers believe that the reproduced skull shape confirmed that the Sahar people have several characteristics as the later primitive people. Among them, the position of the spinal cord into the skull is different from that, it is similar to human beings, which indicates that the Sahar is walking upright.
Rick Potz of the National Natural History Museum of the SMG Senian Society said that this location does not necessarily prove that the Sahar is walking upright. George Washington University Bernard Wood said, although he believes that Sahar people may really be primitive, there is too little evidence. He said that if the Sahar people are not the primitive, it may belong to a extinct species on the evolution tree map.
