Evolution
B. latifrons is thought to have evolved in midcontinent North America from Bison priscus, another prehistoric species of bison which migrated across the Bering land bridge between 240,000–220,000 years ago. B. latifrons was one of many species of North American megafauna which became extinct during the transition from the Pleistocene to the Holocene epoch (an event referred to as the Quaternary extinction event). It is thought to have disappeared some 21,000–30,000 years ago, during the late Wisconsin glaciation. The species was replaced by the smaller Bison antiquus, which in turn evolved into the yet smaller Bison bison — the modern American bison — some 10,000 years ago.

Famous quotes containing the word evolution:
“What we think of as our sensitivity is only the higher evolution of terror in a poor dumb beast. We suffer for nothing. Our own death wish is our only real tragedy.”
—Mario Puzo (b. 1920)
“The evolution of a highly destined society must be moral; it must run in the grooves of the celestial wheels.”
—Ralph Waldo Emerson (1803–1882)
“Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.”
