#Taxonomy
Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are also rarely called #Hominina. Reference: https://www.geol.umd.edu/~tholtz/G204/lectures/204scatterlings.html

The #human clade comprises the genera Sahelanthropus, Orrorin, Ardipithecus, Australopithecus, Kenyanthropus, Paranthropus, Homo.

Their coexistence in Africa lasted from #4Mya to 1 Mya: 🧵

#Taxonomy
Scientists do not refer to the same genera (even less species) when they use the terms #hominin or #homininans. They are therefore avoided here.
This #longThread uses the adjective #human to refer to any species of the tribe #Hominini that is not chimpanzee or bonobo.

Some characteristics that have distinguished such "human" individuals from other primates, living and extinct, include their erect posture, bipedal locomotion, larger brains.

#Taxonomy
#Homininae, also called "African hominids", is a subfamily of #Hominidae. It includes two tribes, with their extant as well as extinct species:
1) the tribe Gorillini (gorillas);
2) the tribe #Hominini (with numerous human species, chimpanzees and bonobos).
Reproduction diverged between 9 and 6 million years ago. 🧵
