12. Homo erectus

6. homo erectus

The control of fire turned the ancestor-australopiths into Homo erectus. Fire use began in one group of ancestor-australopiths, but soon spread throughout all groups, by exchanges of sex partners and group interactions (in a way similar to the dispersion of agriculture later on). The H. erectus population dispersed over Africa and started the first Out of Africa migration into Eurasia.


Traditionally H. erectus is always imagined as a male. So I was glad to find a reconstruction of a female H. erectus on the blog-site “Kay Nou = Our House”. Thanks, Kay Nou. Her digging stick was nice; but she missed her hide bag. So I gave her one. Unlike in this picture, she was never alone on the savanna, nor elsewhere.

Finds from an earlier period, in the archaeological sites Dmanisi (1,7 million years ago) and Flores (descendants of Java hominids from 1,6 million years ago) show a more primitive hominid, with a more primitive toolbox. So many paleos today believe that it was an earlier hominid, H. habilis or H. rudolfensis that spread Out of Africa into the Far East, developing to H. erectus. A later erectus group returned to Africa as ancestors of the Turkana population. For the humanosopher, this theory of a much earlier Out of Africa migration corroborates the early use of fire, because moving out of the tropics requires fire-use.
