1.75 Dmanisi man, Homo georgicus (Georgia, Russia), tiny brain came from Africa, with Homo erectus & Homo habilis characteristics. Common genetic ancestor of humans & Neanderthal.

1.8 Homo erectus evolves in Africa. Striking resemblance to modern humans, but had a brain about 74 percent of size of modern man.  |
flora & fauna in regions not covered by ice are essentially same as those of earlier Pliocene Epoch. |

Emergence of Isthmus of Panama changes ocean circulation patterns & coincides with formation of an Arctic ice cap. |
Plate tectonic interactions result in uplift of Sierra Nevada, formation of Cascade Range, & onset of strike-slip faulting on San Andreas Fault. In Europe, Alps continue to rise.
global climates become cooler & drier.
