 By the end of the LGM, after 20 ka, A Western European lineage, dubbed West European Hunter-Gatherer (WHG) emerges from the Solutrean refugium during the European Mesolithic.These mesolithic hunter-gatherer cultures are substantially replaced in the Neolithic Revolution by the arrival of Early European Farmers (EEF) lineages derived from mesolithic populations of West Asia (Anatolia and the Caucasus).In the European Bronze Age, there were again substantial population replacements in parts of Europe by the intrusion of Ancient North Eurasian (ANE) lineages from the Pontic–Caspian steppes.
