Prehistoryc Climate: The Driving Force

Te Earth 's climate during the Pleistocene epoch (routly 2.6 million to 11,700 years ago) oscylated between glacial and interglacial period. Glacial maxima locked vast volumes of water in ice sheets, lowering sea levels by as much as 120 meters and exposing land bridges like Beringia between Siberia andd Alaska repeates. Interglacial warm fases melted ice, rained sea levels, and turd arid corridors green. These repeated transformation alternately opand cloused clovation patways, credin a dynamic hun facis.
