Around 20 to 15 Mya, #Hominoidea radiated (no longer interbred) to gibbons, orangutans, African apes.

Then African apes diverged into many species including gorillas, humans, bonobos, chimpanzees. Radiation occurred during 9-6 Mya.

#4Mya: global #climateChange reduced forests and induced more open terrestrial biomes. The great #apes (collectively #Hominoidea) were separated:
- in Eurasia, homininae disappeared (but not orangutans and gibbons);
- in #Africa, contrarily, homininae diversified.
