Bone analysis indicates that, during the whole Neolithic period, people's diet contained little food which was not of animal origin.

They traded with distant cities for ivory, gold, and silver, creating what may have been the first commercial link between the East and the West.

Wild animal species (such as wild boar and horse) were leaner compared to their modern-day domesticated equivalents, so much of the fat the Stone Age people ate came from marine mammals, fatty fish and nuts.

Snails where consumed at least 150,000 years ago, with evidence from the Haua Fteah cave (Libya) that indicates early humans used stone ‘drills’ or thorns to extract the molluscs from their shells.

Implements made from mined flint (as distinct from surface flint) are often found in an unused condition, which might indicate they had a ceremonial function.

It is certainly clear that not all were produced simply for use as tools.
