Sahelanthropus is an extinct genus of hominid dated to about during the Late Miocene. The type species, Sahelanthropus tchadensis , was first announced in 2002, based mainly on a partial cranium , nicknamed Toumaï , discovered in northern Chad .
Sahelanthropus tchadensis is thought to be one of the earliest species belonging to the human lineage. Fossils date back to 7 million years ago. [4] The only fossils that remain are five pieces of the jaw, teeth, and a small cranium.
The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
What may be the earliest-known human ancestor, an ape-man called Sahelanthropus tchadensis who lived in Africa roughly 7 million years ago, walked upright for
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
Both Sahelanthropus and Orrorin existed during the estimated duration of the ancestral chimpanzee–human speciation events, within the range of eight to four million years ago (Mya). Very few fossil specimens have been found that can be considered directly ancestral to genus Pan .
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
It has several shared characteristics with chimpanzees, but due to its fossil incompleteness and the proximity to the human-chimpanzee split, the exact position of Ardipithecus in the fossil record is unclear. [6] It is most likely derived from the chimpanzee lineage and thus not ancestral to humans.
