    7 million years ago, in an active primate community on the African continent, a figure stood up at a fork in the road where the ape was about to turn other, taking a small individual step, but becoming a great step for mankind.
    today, this fork in the road is located in a remote desert in Chad. The skull left behind by that figure has been fossilized by the years and unchartedly exposed to people in the wind and sand.
    "This is the earliest known ancient human being," Michel Brune, a professor at the French Academy of Public Studies and leader of the fossil discovery team, told Xinhua in a recent interview.skull fossils were discovered by the Brune team in 2001 and the originals are now in the national scientific research and development centre of Chad, with replicas on display at the National Museum of Chad and the Museum of Black Civilization in Senegal. "Tumai is thought to exist between primate chimpanzees and humans," said Amy Contusan, director of the Museum of Black Civilization. "This statement reflects the controversy that Mr. Toumai has faced.
    the facial images recovered from Tumai's skull can visually illustrate the controversy, restoring the hairs on the avatar and the five men look a bit like orangutans. Experts believe That Tumei is male, and that the fossils show a mixture of apes and humans: skulls are similar in shape to apes, brains are close to chimpanzees, and spacing is similar to gorillas.Just three months after the
    Brune team published their paper on Tumay in the British journal Nature in July 2002, Milford Walpoff of the University of Michigan's Paleoanthrology Laboratory and others published a questioning article in Nature in October, arguing that Tumay is still an ape, not a human.
    there is plenty of evidence to support Thatmai as a human, brune said in a 2005 article in Nature. He told reporters: "Some people say it's a gorilla, the canine teeth will be hollow, and very large, but this is a human canine teeth." The position of the pillow bone on the skull is also different from that of gorillas and chimpanzees, but is consistent with the characteristics of walking upright on both legs. "
    " what is a person? Wu Xiujie
    researcher at the Institute of Paleontology and Paleoanthropology in China, told Xinhua that the focus of the controversy is actually on the definition of man.
    1960s, paleoanthrology generally used the ability to make tools as a dividing line between humans and ancient apes. But it turned out that making tools was not unique to humans, and that animals such as chimpanzees also made tools. Therefore, the ancient anthropological community gradually adopted a new standard: habitual two-legged upright walking.
    Said Wu Xiujie, Tumei's skull's large hole in the pillow bone is as large as ours, indicating that the skull is perpendicular to the spine, indicating that it has habitual two legs walking upright, "which is decisive evidence." She said that tumay is now classified by the academic community as the Sahail Chadian species, although not part of the modern genus, but also belongs to the human family, as with some other ancient humans.since Tumei is human, his age makes special sense. In a 2008 paper published in the National
    Journal, the Brune team said the annual results for Tumay's skull ranged from 6.8 million to 7.2 million years, or 7 million years for convenience. "No human beings have been found more than this," he said. "
    means that the time of human origin has been pushed forward by the map.
    years, Lucy, the famous ancient human fossil, has been called "the old grandmother of mankind". The female skeleton fossil, discovered in Ethiopia in 1974, is highly valued for its integrity and long-term nature. Fossils include skulls, ribs, arm bones and so on, and are by far the most complete fossils of their kind. Its "age" is about 3.5 million years old, after the detection of a long time to sit in the world's top chair.
    more ancient fossils have emerged. An ancient human fossil discovered in Kenya in 2000 was named after the Millennials about 6 million years ago, and won the title of "highest generation". Just over a year later, Toumai was discovered in Chad, pushing back the time of human origin by another million years.
    meaning of Tumai is not only in time, but also in space. Prior to Tumay, since important early human fossils such as Lucy were found in eastern Africa, the famous French paleoanthraist Yves Kopon proposed the "East Side Story" theory that humans originated east of the Grand Canyon in East Africa. Tumay appeared in the deserts of Central Chad, moving about 2,500 kilometers west of the Grand Canyon, breaking the "East Side Story" theory.
    " Tumay's findings illustrate advances in scientific research, Cantusan said. " standing 7 million years ago in Tumei, the earliest ancestor we can see now, is he our ancestor?"
    ordinary people may naturally think so. In Chad, most people know and take pride in Toumai. Abubakar Saleh, a Chadian, said: "It is a great honour that Touma is an ancestor of mankind and that we are descendants of Toumai. But
    experts, the evolutionary tree of human ancestors is far from clear. "Because of the scarcity of fossils, our study of the ancient human evolutionary tree is still blind," Wu said. One
    view that is now "touched" by the paleoanthrology community is the "African origin" of early humans, since the fossils of ancient humans found so far 2 million years ago are all in Africa. "Humans have spent a lot of time in Africa, " Brune said. "
    but there is still controversy in academia about how modern people originated closer to home. For example, for Chinese's ancestors, there is an international view that although there are 1.7 million years ago Yuanmou and 770,000 years ago in Beijing ape-man, but these ancient humans may not have survived the ice age, about 60,000 years ago a group of ancient humans came out of Africa to get here.
    , however, many new fossil evidences have recently been found in The Paleoanthrology community in China, such as The Xuchangs, Daoxians, Huanglongdongs, Chong zuo Homo homoesongs, etc., about 100,000 years ago. The new fossil evidence challenges the idea that "China is no more than 60,000 years old."
    Said Wu Xiujie: "The evolution of the ancient human branches is not an isolated, linear process, but a complex bush-like process." There may be a mix between the branches, some branches may later perish, and new branches may be generated somewhere. The trunk and full picture of the human evolutionary tree has not yet been discovered. It
    it is not clear whether Tumai is the ancestor of today's modern humans, or even the Chadians. "But if you look at it on a particularly long time scale, you can say that Tumei and all of us modern people are relatives, " Wu said. ”
