Pleistocene steppe bison population dynamics
The Late Pleistocene featured extreme climatic shifts which were accompanied by megafaunal extinctions. Bison survived these extinctions, yet much of their population history is obscured by Holocene declines. We sequenced genomes of Pleistocene Eurasian and North American bison dating back ~130,000 years. These were used to examine bison evolution over this time period and understand how Pleistocene bison relate to extant populations.
