Jan 11, 2023 · Beringia itself may have been abandoned or have witnessed a severe decline in the human population after the GI 5 interstadial, which was followed by an episode of extreme cold climate (HE 3) at ca 30 ka . The large-mammal biomass most likely decreased significantly at this time (and dietary sources of vitamin D may have disappeared altogether ...
