Holozoa
The more anthropomorphic primates of the Hominini tribe are placed in the Hominina subtribe. Referred to as hominans, they are characterized by the evolution of an increasingly erect bipedal locomotion. The only extant species is Homo sapiens. Fossil records and mtDNA studies indicate this subtribe branched from the common ancestor with the chimpanzee lineage about 5 to 7 million years ago.
Current evidence suggests that, about 2.6 millio...

Holozoa
The more anthropomorphic primates of the Hominini tribe are placed in the Hominina subtribe. Referred to as hominans, they are characterized by the evolution of an increasingly erect bipedal locomotion. The only extant species is Homo sapiens. Fossil records and mtDNA studies indicate this subtribe branched from the common ancestor with the chimpanzee lineage about 5 to 7 million years ago.
Current evidence suggests that, about 2.6 million years ago, Australopithecus began to diverge into two paths. One path produced Paranthropus, more robust, specialized in a plant food that required a stronger jaw and molars and powerful facial muscles that required a cranial crest, much like a modern gorilla has, to unite them. The other track led to Homo, with a relatively larger brain, more delicate teeth and jaw. Both genera existed at the same time for about 1 and a half million years.
This subtribe is usually considered to include Australopithecus, Paranthropus, Sahelanthropus, Orrorin...
