Got food? A team of scientists at the Salk Institute for Biological Studies think they know how many--if not most--living organisms answer this question. They recently showed that when food supplies dwindle, mammals, fruitflies, or frogs probably activate the same ancient cell signaling pathway in order to conserve energy.
In a study published in the April 25, 2008 issue of Molecular Cell, investigators led by Reuben Shaw, Ph.D., assistant professor in the Molecular and Cell Biology Laboratory of the Dulbecco Center for Cancer Research, report that when mammalian cells sense that glucose and other nutrients are running short, they muffle a cellular protein called raptor, causing cells to slow their growth.

Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests.
The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday.
The report notes that a separate study by researchers at Stanford University estimated that the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age.
The wood handle is partially coalifed with quartz and calcite crystalline inclusions. Tests performed at Battelle Laboratory document the hammer’s unusual metallurgy, 96% iron, 2.6% chlorine and .74% sulfur (no carbon). Density test indicate casting of exceptional quality. A unique coating of FeO, which does not readily form under present atmospheric conditions, appears to inhibit rusting.

i'd say that the evidence for advanced technological achievement (hence at least a city-state sized advanced civilization) is the present day existance of the dozen 'Crystal Skulls'
the first of which were discovered years before abrasive tools for
sculpting shapes of human skulls, ranging from 4" small to 10" large,
and made from quartz crystal...was available to humanity.

CLUE 1: CELLS CONSERVING ENERGY WHEN FOOD IS SCARCE

The interesting element here is not that mammals have developed this mechanism – simple survival dictates that the body reacts this way to a degree, but what is interesting is considering what may have lead to such mechanisms developing across the board.
Now before someone jumps in and claims “of course that mechanism is there, its survival!” – think about this.
Yes, certain peoples in certain would certainly develop this mechanism – food may be perpetually scarce in certain areas, leading the body to conserve energy to survive. But, could this mechanism develop as quickly or effectively in areas lush with vegetation where food is plentiful?
Why would peoples living in such conditions require a mechanism such as this?

CLUE 5: CANNIBALISM
I take some poetic license here and am presenting a basic break down of an idea which occurred to me while researching for this thread.
Cannibalism is one area that has avoided serious scientific scrutiny. Yes, studies have been carried out but nothing which answers the following question has been researched to my knowledge.

Slowly, through time, the practice dwindle away as food returned to normal levels and was merely left as a "ritual" practice.
