What is this Animal: Bison, Buffalo, Beefalo or Cattalo?

Bovid species evolved over millions of years in Africa, Asia, Europe, India and North America.  While historically bison (American and European) are found in North America and Europe, buffalo are really old world species that evolved in Africa and Asia.  Cape and Water buffalo evolved in Africa, while swamp buffalo and other large bovids (Anoa, Banteng, Gaur, Kouprey and Yak) developed in specific regions of Africa, Asia and India.  Domestic cattle are thought to have descend from an extinct wild ox or aurochs in Eurasia (Bos taurus taurus), India and Africa (Bos taurus indicus).
