The evidence used to determine which foods were eaten by prehistoric man is scarce and can be very difficult to interpret. The majority of clues about food usage come from the study of collections of animal bones, sea-food shell mounds, plant food remnants, and faecal remains, at or close to sites of human habitation. Studies of these food left-overs provide some hints as to what foods were available to and used by prehistoric man.

Until 10-12 000 years before the present (bp), humans relied on hunting and gathering for their food. They hunted wild animals such as gazelle, antelope, and deer, as well as fish, crabs, and migratory waterfowl, and gathered foods including shell-fish, root vegetables, grains, pulses, nuts, and fruit. The period between roughly 11 000 and 6000 years bp, which has been termed the Neolithic, was a time of crucial and widespread agricultural revolution. Wild crops such as wheat and barley began to be cultivated, and wild animals such as sheep and goats were tamed and then domesticated.
