It mainly includes a fairly complete skull fossil, nicknamed**Toumaï (Toumaï)**, which means \"hope of life\" in Chadian local language, and was found in (Djurab) in the \u003Cspan class=\"marker\" enus=\"Djurab Desert\" lon=\"18\" lat=\"17\" map=\"HB\" zoom=\"4\">Deshara Desert\u003C/span>.\n\nThe era of the Chadian Shah people was in the late Miocene (23 million years ago -5.33 million years ago). The once vast ancient \u003Cspan class=\"marker\" enus=\"Mediterranean Sea\" lon=\"18\" lat=\"34\" map=\"HB\" zoom=\"3\">Mediterranean\u003C/span> (Tethys) was nearly extinct under the constant pressure of plate movement. It also dried up and bottomed out, connecting Eurasia and Africa. The Himalayas in the distance have just begun to rise, but this later \"roof of the world\" is still inconspicuous. 5 million years ago, its average height was about 2300 meters, only slightly higher than the present Huashan Mountain.\n\nThis species may be a common ancestor of humans and chimpanzees, and is currently (2024) recognized as the earliest hominid species (conditioned by two-legged walking), living in west-central Africa (now Chad) about 7 million to 6 million years ago. The environment they live in should be a sparse forest, and the species should be able to walk upright, thus helping them survive in a variety of habitats, including forests and grasslands.\n\nAt present, we have only found the skull fossils of the Chadian Shah, but the existing research shows that the species has the characteristics of both apes and humans. Among the characteristics of apes are: small brain volume (even slightly less than that of chimpanzees), oblique face, extremely prominent brow bones, and long, narrow skull. Human-like features include tiny fangs, a short middle of the face, and a spinal cord opening below the skull rather than behind it. Among them, the location of the spinal cord opening is crucial, a feature that differs significantly from non-bipedal walking apes.\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/s00016/000124_1704334639478.jpg\" alt=\"Toumaï 图迈的头骨\" />\n\u003Cspan>\nPhoto by EOL &amp; Smithsonian NMNH\n\u003C/span>\n\u003Cp class=\"description\">Tumay's skull proves that the species has a cerebellum and a slanted face, much like a chimpanzee. The size of the skull indicates that the individual was a male. The small, flat fangs are unusual for male primates and one of the earliest distinctive features of humans. The skull (foramen magnum) gave scientists evidence that they were able to walk upright. Tumai lived in an open, open forest, very much the same large, closed forest that chimpanzee ancestors lived in.\u003C/p>\n\u003C/div>\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/s00016/1760236735428_Sahelanthropus_tchadensis_-_TM_266-01-060-1_Global_fond.jpg\" alt=\"不同角度的图迈头骨\" />\n\u003Cspan>\nImage source: \u003Ca href=\"https://en.wikipedia.org/wiki/Sahelanthropus\" target=\"_blank\">Wikipedia\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">different angles of the Tumai skull.\u003C/p>\n\u003C/div>\n\nAlthough there is still some controversy, the population represented by Tumai is currently (2023) considered to be the first species to evolve the ability to walk upright. The skull's foramen magnum (the opening at the base of the skull that connects to the cervical spine) is located on the underside of the skull, more anterior than in apes and other primates. This feature suggests that the Chadian Shah's head is able to be supported on an upright body and is closely related to bipedal walking.\n\n\u003Cdiv class=\"img-container-v1\">\n\u003Cimg src=\"https://image.big-history.online/s00016/000124_1704334678211.png\" alt=\"人类与黑猩猩的枕骨大孔位置对比\" />\n\u003Cspan>\nPhoto by Bing\n\u003C/span>\nComparison of the location of the foramen magnum in \u003Cp class=\"description\">humans and chimpanzees, and the location of the occipital bone in Tumay (right). In the absence of other skeletal fossils, the foramen magnum is one of the key pieces of evidence to determine whether early human ancestors walked upright. Based on this important feature, the mainstream view in the academic community is that Tumay can walk on two feet, but his gait is more primitive, not as robust as the later Australopithecus, which also determines its position in the human evolution map.\n\u003C/p>\n\u003C/div>\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/s00016/000124_1709627786938.jpg\" alt=\"米歇尔·布吕内教授与图迈\" />\n\u003Cspan>\nPhoto by \u003Ca href=\"https://etab.ac-poitiers.fr/coll-jean-rostand-thouars/spip.php?article1598\" target=\"_blank\">etab.ac-poitiers.fr\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">Professor Michel Brunet and Tourmey's facial restoration. In 2020, a team of researchers disagreed, arguing that the Chadian Shah appeared to be closer to walking on all fours than standing upright; if confirmed, the species would likely be moved out of the human family tree. From this, we can also see that it is not easy to determine the trajectory of human evolution.\u003C/p>\n\u003C/div>\n\nTumay's discovery also helped paleoanthropologists overturn a popular \"East Side Story\" theory: about 8 million years ago, the formation of the Great Rift Valley in East Africa caused physical isolation between human ancestors and chimpanzees. The ancestors stayed east of the Great Rift Valley, while the chimpanzees were separated to the west of the Great Rift Valley. The two then evolved separately, eventually forming two different species. However, the location where Tumay was found is about 3000 kilometers away from the Great Rift Valley. Obviously, the distribution of ancient humans in Africa is much larger than expected, so the theory of \"East Side Story\" is invalid.\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/s00016/000124_1704334713107.png\" alt=\"乍得沙赫人艺术想象图\" />\n\u003Cspan>\nPhoto by: Smithsonian NMNH\n\u003C/span>\n\u003Cp class=\"description\">the artistic imagination of the Chadian Shah.\u003C/p>\n\u003C/div>\n\n### Extended reading\n\n\u003Ca href=\"/summary/earth-timeline\" target=\"_blank\">Earth Timeline\u003C/a>\n\n\u003Ca href=\"/summary/evolution-of-humans\" target=\"_blank\">human evolution\u003C/a>\n\n## References\n\n\n\n《给智人的极简人类进化史》 [法] 希尔瓦娜·孔戴米 / [法] 弗朗索瓦·萨瓦提埃；李鹏程[译]；海峡书局 2021-07\n\n《人类起源和迁徙之谜》李辉；上海科技教育出版社 2020\n\n《硬核原始人》何叶紫；浙江文艺出版社 2020-11\n\n\u003Cbr>\n\n\u003Ca href=\"https://www.si.edu/object/3d/sahelanthropus-tchadensis-cranium:9730a62f-a649-44fb-8494-aa7c9b6eb1f8\" target=\"_blank\">乍得沙赫人 3D 模型\u003C/a>\n\n\u003Ca href=\"https://www.nhm.ac.uk/discover/the-origin-of-our-species.html\" target=\"_blank\">The origin of our species\u003C/a>\n\n\u003Ca href=\"https://www.archaeology.org/\" target=\"_blank\">Archaeology\u003C/a>\n\n\u003Ca href=\"https://en.wikipedia.org/wiki/Sahelanthropus\" target=\"_blank\">Sahelanthropus\u003C/a>\n\n\u003Ca href=\"https://humanorigins.si.edu/evidence/human-fossils/species/sahelanthropus-tchadensis\" target=\"_blank\">What does it mean to be human?\u003C/a>\n\n\u003Cbr>\n\n---\n","The Chadian Shah (Tumai), the earliest known hominid species, lived in Africa 7 million years ago.
