ok, but here we're talking about thousand of years, unlike geography culture varies in such a long timespan. In 10000> years you'll find the innovative australian tribe who will find a way to exploit the local staples and build a civilization provided that this is possible
I disagree. We only poorly understand the development of agriculture. Put this way. In the last 12,000 years, we have perhaps 9 independent events where Agriculture was discovered or developed.
This suggests that Agriculture or civilization is not a unique fluke, but a fairly high probability potential event. Despite this, we have hundreds, thousands, perhaps tens of thousands of cultures within this time period who do not develop agriculture.
Even within the general climactic and biological framework, there are literally hundreds of cultures which do not develop agriculture for every one that does. The oversimplified thesis that is attributed to Diamond that sees agriculture an inevitable outcome of the right biological opportunities, and lack of agriculture a function of the wrong opportunities is almost certainly false.
