Extended Version (minimal screen width 991px)

Historical Nomadic Foragers are our latest ancestors. They lived in Africa until 50.000 years ago when they started populating Europe and the other continents. Their life is studied using human archaeology, paleogenetics and anthropology of the contemporary hunter-gatherers and various other scientific disciplines. See concise bibliography.

This infograph, a directed graph, in Scalar Vector Graphic format, is generated from plain text Horn clauses, while also generating a structural proof as a Prolog decaration of the causal relations pictured in the directed graph. You can save that Prolog declaration to test the validity of the logical structure. Just type the instruction prove. at the Prolog prompt after loading the Prolog file. Though of course this is not a prove of its truthvalue.

Logical vality does not mean truth, the content and context of the terms must all be proven separately. For that reason all terms in blue colour are in fact linked to pages containing a well sourced demonstration. In this infograph there are twentysix links to pages. For more info about the intention of the concept, see about.

Disclaimer

These examples of analytic directed graphs serve only to illustrate the possibilities of the concept. In fact, the concept is only really workable if there is an interdisciplinary team working on and monitoring the consistency, completeness and precision of the causal relationships and the underlying explanations. The causal relationships represented by it must start from empirically proven scientific facts. The graphs themselves are not evidence but a tool to present scientifically assumed evidence.
