What is the evidence for the earliest hominin species?
Sahelanthropus was the earliest, dating 7-6 million years ago. Orrorin lived about 6 million years ago, while Ardipithecus remains have been dated to 5.8-4.4 million years ago. At present, the vote is still out as to whether any of these three primates were in fact true hominins and if they were our ancestors.
Why do anthropologists believe that Orrorin Tugenensis was a hominin?
Its discoverers believe this species belongs on the human family tree. They claim that it is dissimilar to the genus Australopithecus, and that this genus should be moved to a side branch on the human tree, leaving Orrorin tugenensis as the earliest direct ancestor of humans .
What features distinguish the earliest hominins from other apes?
Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture , bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language.

How was orrorin Tugenensis dated?
The age of the specimen has been estimated to 6 to 5.8 million years , based on radiometric decay [K-Ar dating], paleomagnetism and biochronology.
What did orrorin Tugenensis look like?
Living around 6 million years ago, Orrorin tugenensis is the one of the oldest early humans on our family tree. Individuals of this species were approximately the size of a chimpanzee and had small teeth with thick enamel , similar to modern humans.
