1. why have complex societies formed? 2. why have complex societies formed only in the past 10,000 years? 3. the genus homo has been around for 2.5 million years - but only recently formed complexity - why? 4. could it be that one time special environmental conditions allowed unprecendented ecosystem exploitation first through hunting in the ice age, and then farming? 5. could it be that a passing environmental "sweet spot" allowed the genus homo to flourish - and that once the unusual weather has passed - the genus homo will find it difficult once again?
