[October 18 AFP] The paper that the skull 1,800,000 good years before a preservation state shows a new proof of being the single variety which was discovered in Georgia and in which initial human beings have broad appearance diversity was announced by the U.S. science journal science (Science) on the 17th, so that he was surprised.
According to the paper which the research team led by a ? Georgia National Museums (Georgian National Museum) superintendent, Mr. David Lordkipanidze (David Lordkipanidze), announced the medieval times in Dmanisi (Dmanisi) in Georgia — a hill — this skull discovered at the ruins of the top city has a projecting frame like an anthropoid, and the beetle jaw, and it is said that a cerebral size is as small as about 1/3 of Homo sapiens.
At these ruins that are in about 100-km distance from ? capital Tbilisi (Tbilisi), five skulls of initial human beings are discovered until now including this thing, and the bone of the jaw is also found in four of them.
Moreover, the stone tool made to ask about having performed meat demolition processing and huge saber Tiger’s (saber-toothed tiger) bone are also excavated simultaneously.
The coauthor of ? paper and the Christoff ツォリコ fur (Christoph Zollikofer) of Switzerland and Zurich University (University of Zurich), It is indicated that possibly it was considered that they were the things of a kind which is different in another situation since these skulls differed in appearance sharply.
“However, since it turns out that these individuals originate in the same geological age as the same place, it seems in principle that a top may show the single individual group of a single variety.”
Although ? research team compared the variation seen by the feature of a skull and the form of the jaw, the frame, and the skull differed, respectively, it was shown clearly that it is within the limits of the standard regarded as all the characteristics belonging to the same kind.
The ? ツォリコ fur says, “Although five individuals of Dmanisi differ clearly mutually, individual specificity’s are not larger than the individual of five Homo sapiens or the individual of five chimpanzees belonging to a specific individual group.”
“We have reached the conclusion that the diversity which is within the limits of one kind is not an exception but a rule.”
? — under this hypothesis, all of “Homo habilis (Homo habilis)”, “gay Rudolf エンシス (Homo rudolfensis)”, etc. of the opinion which some specialists have advanced and it is supposed that a race which is different in Africa exists, it is だ — appearance will call it the ancients of a mutually different “Homo erectus (Homo erectus)” kind.
This hypothesis has suggested that they were immediately spread in Asia although the early human beings belonging to the Homo genus of Homo sapiens discovered first in ? and Africa had the small brain.
