A graphic I created summarizing key cultural and biological milestones.
Note that time is situated on a logarithmic scale. Full resolution image here.
Of course, the hominid line began diverging genetically from that of other primates around 7 million year ago.
Out of Africa
Finally, here is the geography & timeline of the emigration waves out of Africa, courtesy of Huffington Post and National Geographic.

- Emigration paths were radically influenced by the Quaternary glaciation.
- Emigration was largely caused by the Toba supereruption.
This post bears on the history of human- and hominid-like species.
