The Mesolithic ("Middle Stone Age") saw humans adapt to post-Ice Age environments with diversified strategies:
Smaller game than Paleolithic: red deer, roe deer, wild boar, aurochs, beaver, waterfowl. Bows/arrows (microliths), spears, traps, dogs. Seasonal drives.
Critical near coasts, rivers, lakes. Nets (bone/antler gauges), weirs, traps, hooks, harpoons, spears. Eel, salmon, trout, pike, shellfish. Preservation: smoking, drying, fermentation.
Nuts (hazelnut—staple), berries, roots, tubers, seaweed, fungi, eggs. Systematic processing (roasting pits for nuts).
Middens (shell heaps) show massive oyster, mussel, cockle, limpet consumption. Year-round protein.
Not full agriculture, but: transplanting useful plants, burning to encourage browse, protecting wild stands, sowing gathered seeds. Pre-domestication cultivation (rye at Abu Hureyra ~11,000 BCE).
Obsidian, amber, shells, pigments, finished tools moved 100s of km—social networks buffered local scarcity.
This flexibility allowed population growth and sedentism, setting the stage for Neolithic farming.
