Every species has a history, and that history is a part of the species as much as an individual's history is a part of the individual. It both creates and limits the species' possibilities. This chapter, on ancestors and relatives, traces the bison lineage, especially in North America, and establishes the place of the modern species Bison bison, which emerged only about 5,000 years ago. The first bison to cross Beringia were not the first bison. Bison branched off from the primitive cow family line — Leptobos — about a million years ago. The first bison were small-bodied, small-horned, fast-moving residents of forest edges and meadows. Gradually, the bison line became northern specialists, able to live where other cattle couldn't. They also became open grassland specialists.
